Induction and Enhancement of Bacteriocin Production (Review)

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Conventionally, bacteriocins are produced by microorganisms on complex substrates, released as semi‐purified preparations or crude fermentates. These bacteriocin‐containing products often exhibit unsatisfactory purity, low active‐substance content, and high production costs, limiting their commercialization and use. This review aims to analyze

Synthesis of leucine-based cyclic dipeptides

Proceedings of the National Academy of Sciences of Belarus, Chemical Series, 2020
3-benzyl-6-isobutylpiperazin-2,5-dione [cyclo(leucylphenylalanyl)], 3-isobutylpiperazin-2,5-dione [cyclo(-leucylglycyl)] and 3-(sec-butyl-)-6-isobutyl-piperazine-2,5-dione [cyclo(leucylisoleucine)] have been obtained by cyclization of methyl esters of tert-butyloxycarbonyl derivatives of dipeptides, for the synthesis of which both carbodiimide-promoted

Reversible Cystine Disulfide Scaffolding Enables Carbonyl Sulfide‐Mediated Intramolecular Peptide Bond Formation via Cyclocystine: Implications for Prebiotic Chemistry

Chemistry – A European Journal, EarlyView.
Cystine is unique among amino acids, in that the disulfide bond can allow intramolecular peptide bond formation. This cyclization offers potential advantages for intramolecular coupling selectivity in prebiotic peptide formation. ABSTRACT Treatment of cystine (the disulfide‐linked dimer of cysteine) with carbonyl sulfide (COS) results in the formation ...

Effects of Cyclic High Ambient Temperature on Muscle Imidazole Dipeptide Content in Broiler Chickens

The Journal of Poultry Science
Imidazole dipeptides possess important bioregulatory properties in animals. This study aimed to evaluate the effect of high ambient temperature on muscle imidazole dipeptides (carnosine, anserine, and balenine) in broiler chickens.

C‐Terminal Functionalization Methods of Amino Acids, Peptides, and Proteins

Chemistry – A European Journal, EarlyView.
C‐terminal functionalization offers powerful routes to peptide and protein diversification, yet epimerization, hydrolysis, and selectivity remain key challenges. This Review surveys enzymatic, decarboxylative, and condensation strategies, highlighting advances toward chemo‐ and regioselective, protecting‐group‐free, atom‐efficient methods applicable to
