Resumen

Abstract Vaccines designed to prevent or to treat hepatitis C viral infection must achieve maximum cross-reactivity against widely divergent circulating strains. Computer-generated sequences minimize genetic distance between circulating strains, and can be generated as a consensus sequence (most common amino acid at each position) or a representative sequence (derived with Bayesian and maximal likelihood phylogenetic tools). Broad recognition of such sequences in HCV has not been demonstrated. Consensus and representative sequences were generated from 390 full-length HCV genotype 1a polypeptid

Yeast autonomously replicating sequence (ARS) elements are composed of a conserved 11-base-pair (bp) core consensus sequence and a less well defined 3'-flanking region. We have investigated the relationship between the H4 ARS core consensus sequence and its 3'-flanking domain. The minimal sequences necessary and sufficient for function were determined by combining external 3' and 5' deletions to produce a nested set of ARS fragments. Sequences 5' of the core consensus were dispensable for function, but at least 66 bp of 3'-flanking domain DNA was required for full ARS function. The importance

Resumen

Heparin-binding proteins may contain specific patterns of basic amino acids, called consensus sequences, that interact with heparin. Small peptides were synthesized that contained consensus sequences (i.e. FAKLNCRLYRKANKSSK) or disrupted consensus sequences (i.e. K136-->A) based on the known sequence of antithrombin III (amino acid residues 123-139). These peptides were then examined in both competitive and non-competitive binding experiments using bioassays, fluorescence spectroscopy, affinity chromatography and n.m.r. spectroscopy.

Resumen

During studies of kinase phosphorylation, not all functional kinase phosphorylation may be found using consensus sequence patterns. This type of phosphorylation is termed ‘non-consensus’ or ‘cryptic’ phosphorylation. Results presented here based on molecular dynamics of short peptides show that protein kinases may phosphorylate not only established consensus sequences (reading a sequence from N-terminus to C-terminus) but also reversed consensus sequences (reading from C- to N-terminus). Several protein sequences were analysed and corresponding biochemical data were presented. Similarity of mo

Resumen

A wide variety of proteins have been shown to recognize and bind to specific amino acid sequences on other proteins. These sequences can be readily identified using combinatorial peptide libraries. However, peptides containing these preferred sequences (“consensus sequence peptides”) typically display only modest affinities for the consensus sequence-binding site on the intact protein. In this report, we describe a parallel synthesis strategy that transforms consensus sequence peptides into high affinity ligands.

ABSTRACT It is well established that cell-free infection with human T-cell leukemia virus type 1 (HTLV-1) is less efficient than that with other retroviruses, though the specific infectivities of only a limited number of HTLV-1 isolates have been quantified. Earlier work indicated that a postentry step in the infectious cycle accounted for the poor cell-free infectivity of HTLV-1. To determine whether variations in the pol gene sequence correlated with virus infectivity, we sequenced and phenotypically tested pol genes from a variety of HTLV-1 isolates derived from primary sources, transformed

Resumen

ABSTRACT The varicella-zoster virus (VZV) IE62 protein is the major transcriptional activator. IE62 is capable of associating with DNA both nonspecifically and in a sequence-specific manner via a consensus binding site (5′-ATCGT-3′). However, the function of the consensus site is poorly understood, since IE62 efficiently transactivates promoter elements lacking this sequence. In the work presented here, sequence analysis of the VZV genome revealed the presence of 245 IE62 consensus sites throughout the genome. Some 54 sites were found to be present within putative VZV promoters. Electrophoreti

Resumen

ABSTRACT The packaging signal (ψ) of human immunodeficiency virus type 2 (HIV-2) is present in the 5′ noncoding region of RNA and contains a 10-nucleotide palindrome (pal; 5′-392-GGAGUGCUCC) located upstream of the dimerization signal stem-loop 1 (SL1). pal has been shown to be functionally important in vitro and in vivo. We previously showed that the 3′ side of pal (GCUCC-3′) is involved in base-pairing interactions with a sequence downstream of SL1 to make an extended SL1, which is important for replication in vivo and the regulation of dimerization in vitro. However, the role of the 5′ side

Resumen

The diagnosis of HPV infection is generally carried out using immunological and molecular techniques based on high risk to probable high-risk HPV strains. The aim of this work is to generate a global representation of HPV strains for diagnosis and drug development. In this work, all the complete genomic DNA sequences of registered Human Papillomavirus (HPV) strains available in NCBI GenBank were used to obtain a consensus sequence of HPV using the Genetic Algorithm. The consensus DNA sequence was translated using the ExPASy software tool. In all, six longest amino acids frames were selected fr

Resumen

Seven of the eight genes in the avian pneumovirus (APV) genome contain a conserved 9 nt transcriptional start sequence with the virus large (L) polymerase gene differing from the consensus at three positions. The sequence requirements of the APV transcriptional gene start sequence were investigated by generating a series of mutations in which each of the nine conserved bases was mutated to each of the other three possible nucleotides in a minigenome containing two reporter genes. The effect of each mutation was assessed by measuring the relative levels of expression from the altered and unalte

Resumen

ABSTRACT Adaptation in bacterial chemotaxis involves reversible methylation of specific glutamate residues within the cytoplasmic domains of methyl-accepting chemotaxis proteins. The specific sites of methylation in Salmonella enterica and Escherichia coli chemoreceptors, identified 2 decades ago, established a consensus sequence for methylation by methyltransferase CheR. Here we report the in vitro methylation of chemoreceptors from Thermotoga maritima, a hyperthermophile that has served as a useful source of chemotaxis proteins for structural analysis. Sites of methylation have been identifi

Resumen

Sequence analysis frequently requires intuitive understanding and convenient representation of motifs. Typically, motifs are represented as position weight matrices (PWMs) and visualized using sequence logos. However, in many scenarios, in order to interpret the motif information or search for motif matches, it is compact and sufficient to represent motifs by wildcard-style consensus sequences (such as [GC][AT]GATAAG[GAC]). Based on mutual information theory and Jensen-Shannon divergence, we propose a mathematical framework to minimize the information loss in converting PWMs to consensus seque

Resumen

We report the complete sequence of Drosophila alpha-spectrin and show that it is similar to vertebrate nonerythroid spectrins. As in vertebrates, the alpha subunit consists of two large domains of repetitive sequence (segments 1-9 and 11-19) separated by a short nonrepetitive sequence (segment 10). The 106-residue repetitive segments are defined by a consensus sequence of 54 residues. Chicken alpha-spectrin (Wasenius, V.-M., M. Saraste, P. Salven, M. Eramaa, L. Holm, V.-P. Lehto. 1989. J. Cell Biol. 108:79-93) shares 50 of these consensus positions. Through comparison of spectrin and alpha-act

Resumen

ABSTRACT The genetic heterogeneity of HIV-1 poses a major obstacle to vaccine development. Although most horizontally acquired HIV-1 infections are initiated by a single homogeneous virus, marked genetic diversification and evolution occur following transmission. The relative contribution of the antiviral immune response to intrahost viral evolution remains controversial, in part because the sequence of the transmitted virus and the array of T-cell epitopes targeted by both donor and recipient are seldom known. We directly compared predominant viral sequences derived from 52 mother-child trans

SummaryThe 15,160 bp murine gene encoding anticoagulation protein C (PC) was cloned and sequenced, including 414 bp upstream of exon 1 and 80 bp downstream of the translation stop codon. Nine exons and eight introns were identified. The first exon was untranslated and contained the major transcriptional start site, the surrounding nucleotide sequence of which matched reasonably well with the consensus eukaryotic Cap element sequence. The translational initiator methio-nine residue was located in exon 2. The other introns were positioned as splices between the major domain units of the protein.

Resumen

Abstract Mitochondrial transcription factor A (TFAM) plays a critical role in mitochondrial transcription initiation and mitochondrial DNA (mtDNA) packaging. Both functions require DNA binding, but in one case TFAM must recognize a specific promoter sequence, while packaging requires coating of mtDNA by association with non sequence-specific regions. The mechanisms by which TFAM achieves both sequence-specific and non sequence-specific recognition have not yet been determined. Existing crystal structures of TFAM bound to DNA allowed us to identify two guanine-specific interactions that are est
