Protease (PR), proteinase, or peptidase refers to a group of proteolytic enzymes whose major function is to catalyze the hydrolysis of peptide bonds that link amino acids together in a polypeptide chain with high sequence selectivity and catalytic proficiency. ...
2B). Consistent with many viral protease inhibitors21, there was a steep response to increasing doses of PF-00835231, with a ~2–3 fold difference between EC50 and EC90 in both cell types (EC90 = 0.48 µM in VeroE6-enACE2 cells and EC90 = 1.6 µM in VeroE6-...
Here, we show that protease-sensitive abnormal PrP aggregates derived from patients with sporadic Creutzfeldt-Jakob disease are taken up and degraded by immortalized human astrocytes similarly to abnormal PrP aggregates that are resistant to proteases. Our data suggest that relative proteinase K ...
We determined the structure of proteinase K at the resolution of 0.98 Å by SRX (Table 1). Substantial differences between SFX and cryo-cooled SRX structures were also found in disulfide bonds as well as the Ca binding site, which are responsible for the stability and activity of ...
SARS-CoV-2 3C-like proteinase (3CLP) is a crucial protease and plays a key role in the viral life cycle, as it controls replication, and thus, it is viewed as a target for drug design. Methods:: In this study, we performed structure-based virtual screening of FDA drugs approved ...
Mice displayed a plasma protein binding rate of 97.7%, whereas rats showed 99.9%, a difference of ~ 20 fold regarding the unbound concentration of BI-9740. In an efficacy model in mice, administration of BI-9740 led to a reduction of NE activity by 91%, proteinase 3 by 97%, and ...
The greatest variation from the proteinase K polypeptide is in loop 114-134 and is due to the absence of a disulfide bridge in the P. cyclopium protease that is present in proteinase K. A difference was also observed in the orientation of the histidine in the catalytic triad, though this ...
Future research has to determine the reason for such transcription difference of SAG12 homologous cysteine proteases in soybean determinate nodules and Medicago indeterminate nodules. To analyze any endogenous cystatin function in nodules, it is crucial to identify their possible endogenous target cysteine ...
There was little difference between MS and normal brains in their phospholipid content. The significant finding was the demonstration that with a partial or total destruction of the encephalitogenic protein around the plaques, a 4-fold increase in acid proteinase occurred. Previous reports ( Chao ...
In the case of potatoes, protease inhibitors of the serine proteinase variety function as the plant’s source of defense. The study conducted by Kim et al. (2005) examined the antimicrobial activity of the potato protease inhibitor, potamin-1 (PT-1). This peptide demonstrated antimicrobial ...
