Owing to their superior catalytic activity in the extreme conditions, extremozymes have found the potential biotechnological applications for industrial purposes. A robust extracellular protease activity was detected in the culture broth of Salicola marasensis, an extreme halophilic bacterium, after a 48 h-incubation. The effect of different media ingredients in a liquid state fermentation was ...

PURPOSE The role of exoproteins in the pathogenesis of Pseudomonas aeruginosa keratitis was investigated in three animal models by assessing the relationship between corneal virulence and the activities of exotoxin A, elastase, alkaline protease, and an uncharacterized protease, protease IV. METHODS The four Pseudomonal strains tested included a prototype strain (ATCC 27853) producing exotoxi...

Human immunodeficiency virus type 1 (HIV-1) expresses its structural and functional proteins within Gag-Pol precursor polyproteins. Specific proteolytic processing of the precursors by the viral protease is critical for the maturation and infectivity of viral particles. To observe the influence of autoprocessing on the activation of recombinant HIV-1 protease, we constructed different HIV-1 pro...

Two proteases produced by the SARS-CoV-2 virus, main protease and papain-like protease, are essential for viral replication have become focus of drug development programs treatment COVID-19. We screened a highly focused library compounds containing covalent warheads designed to target cysteine identify new lead scaffolds both Mpro PLpro proteases. These efforts identified small number hits no v...

Wheat germ and fish skin usually has not been completely utilized sometimes may be discarded, thus causing a lot of waste. Here, we aim at exploring the therapeutic anti-inflammatory effects protease hydrolysates wheat on ulcerative colitis (UC) mice. In current study, protein (WGPH) gelatin (FSGH) treated mice had longer colon than DSS-induced Moreover, reversed gut dysbiosis. Protease were li...

The protease enzyme produced by Lactic Acid Bacteria (LAB) with characteristics similar to rennin is called Rennin Like Protease (RLP). purpose of the study was obtain information on biochemical RLP Enterococcus faecium 1.15 as a basis for utilization enzyme. first stage observation growth curves and potential isolates produce RLP, characterization. (RLP) which has been purified using Sephadex ...

Penelitian bertujuan untuk mengetahui potensi senyawa eugenol dan turunannya sebagai inhibitor HIV-1 Protease (PR) kandidat antivirus HIV-1. Ligan digunakan dalam penelitian adalah eugenol, metil asetil isoeugenol. Hasil men...

alpha-Lytic protease, a chymotrypsin-like serine protease, is synthesized with an N-terminal 166 amino acid pro region which is absolutely required for folding of the protease. The pro region is also the most potent inhibitor of the protease known with a Ki of approximately 10(-10) M. Compared to its role in the folding reaction, relatively little is known about the mechanism by which the pro r...

Proteases are essential for regulating a wide range of physiological and pathological processes. The imbalance of protease activation and inhibition will result in a number of major diseases including cancers, atherosclerosis, and neurodegenerative diseases. Although fluorescence resonance energy transfer (FRET)-based protease probes, a small molecular dye and other methods are powerful, they s...
