Microorganisms, 2021 Vibrio cholerae can survive cold stress by entering into a viable but non-culturable (VBNC) state, and resuscitation can be induced either by temperature upshift only or the addition of an anti-dormancy stimulant such as resuscitation-promoting factors ...

Calpain small subunit homodimerization is robust and calcium‐independent
FEBS Letters, EarlyView.Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Proteolytic Cleavage of Various Human Serum Proteinase Inhibitors by Candida albicans Aspartic Proteinase [PDF]
, 2008 The secreted Candida albicans aspartic proteinase (SAP) is presumed to be one of the putative Candida virulence factors, while serum proteinase inhibitors depend on host defense mechanisms.

FEBS Letters, EarlyView.This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation
FEBS Letters, EarlyView.Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Bacterial enzymes as potential feed additives in poultry farming
Учёные записки Казанского университета: Серия Естественные науки, 2019 The problem of obtaining economic benefits in poultry breeding from complete absorption of feeds by domestic fowls through increasing the digestibility of nutrients remains urgent.

Molecular Oncology, EarlyView.ERRFI1, a neural crest (NC)‐associated gene, was upregulated in melanoma and negatively correlated with the expression of melanocytic differentiation markers and the susceptibility of melanoma cells toward BRAF inhibitors (BRAFi). Knocking down ERRFI1 significantly increased the sensitivity of melanoma cells to BRAFi.

Cellular locations of proteinases and association with vesicles in
European Journal of Medical Research, 2010 We found that locations of arginine-specific gingipain (RGP) in the cellular fractions in the crude extract, envelope, vesicles, and culture supernatants were 48%, 16%, 17%, and 31%, respectively, and the corresponding values of lysine-specific gingipain

Primary structure of potato Kunitz-type serine proteinase inhibitor [PDF]
, 2000 The serine proteinase inhibitor (PSPI-51) isolated from potato tubers (Solanum tuberosum L,) comprises two protein species with pi 5.2 and 6.3, denoted as PSPI-21-5.2 and PSPI-21-6.3, respectively.
