Enzymatic and Non-Enzymatic Virulence Activities of Dermatophytes on Solid Media [PDF]

open access: yesJournal of Clinical and Diagnostic Research, 2017
Introduction: Dermatophytes are keratinophilic fungi causing superficial cutaneous infections that account 20-25% of the global population. As per literature search, there is a dearth in the study on virulence factors of dermatophytes from the Indian

A neutrophil-dependent pathway for the generation of a neutral peptide mediator: partial characterization of components and control by alpha-1-antitrypsin. [PDF]

open access: yes, 1974
A biologically active neutral peptide mediator is cleaved from a plasma protein substrate by an alpha-1-antitrypsin-inhibitable serine protease apparently residing on the membrane of the human neutrophil. The peptide mediator has an approximate mol wt of

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

open access: yesFEBS 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

Pentamidine inhibition of streptopain attenuates Streptococcus pyogenes virulence

open access: yesMicrobiology Spectrum
The obligate human pathogen Streptococcus pyogenes (also known as GAS; Group A Streptococcus) carries high morbidity and mortality, primarily in impoverished or resource-poor regions. The failure rate of monotherapy with conventional antibiotics is high,

The Picornavirus Precursor 3CD Has Different Conformational Dynamics Compared to 3Cpro and 3Dpol in Functionally Relevant Regions

open access: yesViruses, 2021
Viruses have evolved numerous strategies to maximize the use of their limited genetic material, including proteolytic cleavage of polyproteins to yield products with different functions.

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

open access: yesFEBS 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.

The role of enzymes in the formation of meat and meat products

open access: yesТеория и практика переработки мяса
The meat industry is one of the most dynamic and competitive sectors of the food industry. As the global population keeps on growing and the demand for protein does the same, the consumers define ever higher standards of quality for the meat producers ...

Resistance of the 64K protein of budded Autographa californica nuclear polyhedrosis virus to functional inactivation by proteolysis. [PDF]

open access: yes, 1988
The 64K surface protein of budded Autographa californica nuclear polyhedrosis virus (AcMNPV BV) is known to play a role in the functional entry of AcMNPV BV into Spodoptera frugiperda IPLB-SF-21 cells by adsorptive endocytosis.

Protease inhibitors targeting coronavirus and filovirus entry. [PDF]

open access: yes, 2015
In order to gain entry into cells, diverse viruses, including Ebola virus, SARS-coronavirus and the emerging MERS-coronavirus, depend on activation of their envelope glycoproteins by host cell proteases.
