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

Antioxidant properties of Enterobacter cloacae C3 lipopeptides in vitro and in model food emulsion [PDF]

, 2019
The present work aims to investigate the in vitro antioxidant activities of Enterobacter cloacae C3 lipopeptides, as well as the stability of sunflower oil in water (o/w) emulsion and the conservation of raw beef patties. The C3 lipopeptides were assayed

Mechanism of Isonitrilase, a Nonheme Iron Decarboxylase Involved in the Biosynthesis of the Isonitrile Group in Peptides: A Computational Study

Chemistry – A European Journal, EarlyView.
A combination of molecular dynamics and quantum mechanics calculations shows that substrate is tightly bound inside the enzyme structure that enables two successive catalytic cycles with dioxygen and α‐ketoglutarate with an initial desaturation followed by hydrogen abstraction and decarboxylation steps to form an isonitrile substituent.

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

Lipopeptides are effective stimulators of tyrosine phosphorylation in human myeloid cells [PDF]

, 1992
Synthetic lipopeptide analogues of the N-terminus of bacterial lipoprotein are effective activators of macrophages, neutrophils and lymphocytes. We studied the effect of the lipopeptide N-palmitoyl-S-[2,3-bis(palmitoyloxy)-(2RS)-propyl]- (R)-cysteinyl-(S)

Crosstalk Between Parkinson's Disease and Colorectal Cancer: Genetic Mechanisms, Gut Microbiota, and Therapeutic Insights

Health Care Science, EarlyView.
This review elucidates the crosstalk between Parkinson's disease and colorectal cancer, driven by shared genetics (PRKN, PINK1, DJ‐1) involving oxidative stress, cell cycle regulation, and inflammation. It identifies the gut microbiota—via functional amyloids and short‐chain fatty acids (SCFAs)—as a mechanistic bridge, offering insights for dual ...
