Abstract:
While thiol-based catalysts are widely employed for chemical protein synthesis relying on peptide thioester chemistry, this is less true for selenol-based catalysts whose development is in its infancy. In this study, we compared different selenols derived from the selenocysteamine scaffold for their capacity to promote thiol–thioester exchanges in water at mildly acidic pH and the production of peptide thioesters from bis(2-sulfanylethyl)amido (SEA) peptides. The usefulness of a selected selenol compound is illustrated by the total synthesis of a biologically active human chemotactic protein,

Abstract:
The argyrins are secondary metabolites from myxobacteria with antibiotic activity against Pseudomonas aeruginosa. Studying their structure–activity relationship is hampered by the complexity of the chemical total synthesis. Mutasynthesis is a promising approach where simpler and fully synthetic intermediates of the natural product’s biosynthesis can be biotechnologically incorporated. Here, we report the synthesis of a series of tripeptide thioesters as mutasynthons containing the native sequence with a dehydroalanine (Dha) Michael acceptor attached to a sarcosine (Sar) and derivatives.

Abstract:
ABSTRACT Chemobiosynthesis (J. R. Jacobsen, C. R. Hutchinson, D. E. Cane, and C. Khosla, Science 277:367-369, 1997) is an important route for the production of polyketide analogues and has been used extensively for the production of analogues of 6-deoxyerythronolide B (6-dEB). Here we describe a new route for chemobiosynthesis using a version of 6-deoxyerythronolide B synthase (DEBS) that lacks the loading module. When the engineered DEBS was expressed in both Escherichia coli and Streptomyces coelicolor and fed a variety of acyl-thioesters, several novel 15-R-6-dEB analogues were produced. Th

Abstract:
N→S Acyl transfer is a popular method for the postsynthesis production of peptide C α-thioesters for use in native chemical ligation and for the synthesis of head-to-tail cyclic peptides. Meanwhile thioester formation at the side chain of aspartic or glutamic acids, leading to tail-to-side-chain-cyclized species, is less common. Herein we explore the potential for cysteine to function as a latent thioester when appended to the side chain of glutamic acid. Initial insights gained through study of C-terminal β-alanine as a model for the increased chain length were ultimately applied to peptide m

The target molecules were obtained from a common precursor aldehyde in the form of N-acetylcysteamine (SNAc) thioesters and methyl esters in 13 to 15 steps. Key steps for the assembly of the polyketide backbone of the dehydratase substrate analogue were a Yamamoto asymmetric carbocyclisation and a Sakurai allylation as well as an anti-selective

Abstract:
Two structurally different aromatic dithioesters were synthesized from two dithiols and methacryloyl chloride. The polymer networks based on methyl methacrylate and/or styrene and the new dimethacrylates were subsequently prepared. The polymerization yields of copolymers were in the range of 95–99%. The thermal and mechanical properties of the copolymers were determined by means of differential scanning calorimetry (DSC), thermogravimetric analysis (TG/DTG), and Shore D hardness.

Abstract Maintenance of the mitochondrial respiratory chain complexes plays crucial role for the aerobic metabolism of the eukaryotes such as unicellular yeasts, for example, Saccharomyces cerevisiae as well as of human being. Mitochondrial respiratory function has been studied using the yeast S. cerevisiae as a model organism. Since yeast cells are also able to grow without respiration by fermentation, identification of the nuclear genes linked to respiratory function is possible by generation of nuclear gene deletions and testing for respiration-deficient phenotype of the yeast deletion str

Abstract Fatty acids are one of the most essential categories of biological lipids and their synthesis and degradation are vital for all organisms. Severely compromised phenotypes of yeast mutants and human patients, which have defective components in their degradative or synthetic processes for fatty acid metabolism, have highlighted the importance of these processes for overall metabolism. Most fatty acids are degraded by β-oxidation, which occurs in mitochondria and peroxisomes in mammals, whereas synthesis is catalyzed by cytosolic multifunctional peptides, although a synthesis system invo

Abstract A data base search using the amino acid sequence of Saccharomyces cerevisiae Etr1p, the last enzyme of mitochondrial fatty acid synthesis type II (FAS II), revealed a highly similar human protein, NRBF-1. Expression of NRBF-1 in a yeast etr1Δ strain rescued its respiratory deficiency. NRBF-1 resides in mitochondria in cultured HeLa cells. The recombinant NRBF-1 is enzymatically active, reducing 2E-enoyl-CoAs to acyl-CoAs in an NADPH-dependent manner. Altogether, our data showed that NRBF-1 is a mitochondrial 2-enoyl-CoA reductase/2-enoyl thioester reductase (MECR/ETR1), the human fun
