AbstractA complete chitin deacetylase (CDA) complementary DNA (cDNA) from Mucor racemosus was cloned and sequenced by reverse transcription-polymerase chain reaction (RT-PCR) and rapid amplification cDNA end (RACE) with gene special conserved primers. The cDNA sequence was submitted to GenBank (DQ538514). The complete cDNA with full-length of 1506 bp contained a 67 bp 5′-untranslated region, an open reading frame of 1344 bp and 95 bp 3′-untranslated region including tailing site AATAAA.

Abstract Homologs of the Escherichia coli (mutL, S and uvrD) and Streptococcus pneumoniae (hexA, B) genes involved in mismatch repair are known in several distantly related organisms. Degenerate oligonucleotide primers based on conserved regions of E. coli MutS protein and its homologs from Salmonella typhimurium, S. pneumoniae and human were used in the polymerase chain reaction (PCR) to amplify and clone mutS/hexA homologs from Saccharomyces cerevisiae. Two DNA sequences were amplified whose deduced amino acid sequences both shared a high degree of homology with MutS. These sequences were th

This protein forms a molecular complex ("staphylothrombin") with human prothrombin in a molar ratio of 1:1. The complex displays the ability to clot fibrinogen and to hydrolyze the synthetic tripeptide substrates for α-thrombin. The formation of staphylothrombin does not require proteolytic cleavage of the prothrombin molecule, and this mechanism differs markedly from the activation process by either blood-clotting factor Xa or snake venom procoagulant.In the present studies, a pAT15

Abstract:
Finding homologous proteins and grouping them are tasks of utmost importance in biology, which currently rely on tools based on information from these proteins' DNA or amino acid sequences. These tasks require identifying evolutionary patterns that are challenging to obtain automatically using traditional methods. This work proposes a data modeling approach to leverage evolutionary patterns in homology searching, ranking, and clustering tasks through an alignment-free process using image similarity algorithms. This strategy is valuable even for distant homologs and contributes to data privacy

Abstract:
Leptospirosis is a worldwide zoonotic disease. Pathogenesis of leptospirosis is not well understood. Identification of virulence factors of pathogenic Leptospira and their roles in pathogenesis is crucial. Based on available whole-genome sequences of Leptospira, two presumptive virulence genes which are homologous to the invasionA (invA) gene of Rickettsia prowazekii and the mammalian cell entry (mce) gene of Mycobacterium tuberculosis, have been identified. The function of these genes may involve in the attachment and invasion of eukaryotic cells. We proposed that these gene homologues should

Abstract:
We have reported that localization of TMV in tobacco cultivars with the N gene, is associated with a 23 K protein (IVR) that inhibited replication of several plant viruses. This protein was also found in induced resistant tissue of Nicotiana glutinosa x Nicotiana debneyi. During the present grant we found that TMV production is enhanced in protoplasts and plants of local lesion responding tobacco cultivars exposed to 35oC, parallel to an almost complete suppression of the production of IVR. We also found that IVR is associated with resistance mechanisms in pepper cultivars. We succeeded to clo

Abstract:
Ustilago maydis is a fungal pathogen of maize. Some strains of U. maydis encode secreted polypeptide toxins capable of killing other susceptible strains of U. maydis. Resistance to the toxins is conferred by recessive nuclear genes. The toxins are encoded by genomic segments of resident double-strande RNA viruses. The best characterized toxin, KP6, is composed of two polypeptides, a and b, which are not covalently linked. It is encoded by P6M2 dsRNA, which has been cloned, sequenced and expressed in a variety of systems. In this study we have shown that the toxin acts on the membranes of sensi

The original objectives of the approved proposal were: 1. To construct a YFP fused Arabidopsis cDNA library in a mammalian expression vector. 2. To infect the library into a host fibroblast cell line and to screen for new cytoskeletal associated proteins using an automated microscope. 3. Isolate the new genes. 4. Characterize their role in plants. The project was approved as a feasibility study to allow proof of concept that would entail building the YFP library and picking up a couple of positive clones using the fluorescent screen.

Abstract:
Leguminous forage crops are high in proteins but deficient in S- amino acids. It has been shown that both wool quality and milk production can be limited by the post-ruminal supply of sulfur-containing amino acids. Efforts to use conventional plant breeding and cell selection techniques to increase the S-amino acid content of alfalfa have met with little success. With the objective to increase the S-amino acid content of forage legumes, the goal of this project was to co- express the methionine rich zein genes from corn along with a gene for a key enzyme in methionine biosynthesis, aspartate k

CDs are the products of enzymatic conversation of starch and related substrates by cyclodextrin glucanotransferases (CGTases), and are useful carrier molecules for applications in industries. The CGTase consists of 5 domains, A, B, C, D, and E. Domains A/B are the central catalytic domains while others perform accessory functions. The commercial production of CDs required that the starch be liquefied at high temperature before the CGTase reaction at

Abstract:
Loss of function mutations in the farnesyltransferase β subunit gene ERA1 (enhanced response to abscisic acid), cause abscisic acid hypersensitivity in seedlings and in guard cells. This results in slowed water loss of plants in response to drought. Farnesyltransferase (PFT) catalyses the attachment of the 15-carbon isoprenoid farnesyl to conserved cysteine residues located in a conserved C-terminal domain designated CaaX box. PFT is a heterodimeric protein comprised of an a and b sununits. The a subunit is shared between PFT and geranylgeranyltransferase-I (PGGTI) which catalyses the attachem
