The lysis time of euglobulin clots made with whole blood (plasma and red cells) was very much shorter than that of clots made with plasma alone, indicating a fibrinolytic component in red cells. A plasminogen activator was found in the stroma-free hemolysate, and proteolytic activity was found in the stromal fraction. The plasminogen activator, purified by using diethylaminoethyl-cellulose (DEA...

N, N-Dimethyl proteins were prepared by reductive methylation of their amino groups with formaldehyde and NaBH4. Proteolysis of these alkylated proteins by trypsin, or-chymotrypsin, subtilisin, pepsin, and fungal protease was determined by direct measurement of the bonds split, with the use of trinitrobenzenesulfonic acid to determine directly the appearance of new terminal amino groups. The lo...

The proactive use of topical anti-inflammatory (TAI) therapy to address subclinical inflammation is an effective, contemporary clinical strategy for the management of atopic dermatitis (AD). The interaction of a proactive TAI dose with the subclinical epidermal barrier defect in AD is yet to be determined. A randomised, observer-blind, functional mechanistic study in 17 subjects with quiescent ...

Previously, we showed that mutations in Mycobacterium tuberculosis panD, involved in coenzyme A biosynthesis, cause resistance against pyrazinoic acid, the bioactive component of the prodrug pyrazinamide. To identify additional resistance mechanisms, we isolated mutants resistant against pyrazinoic acid and subjected panD wild-type strains to whole-genome sequencing. Eight of the nine resistant...

Recent studies suggest that mast cell-derived neutral proteases can activate matrix-degrading metalloproteinases (MMPs). We have investigated the role of the mast cell proteases tryptase and chymase in the activation of MMPs in human carotid endarterectomy specimens (atherosclerotic, n=32) and postmortem carotid arteries (control, n=17). In vitro degranulation of mast cells in atherosclerotic c...

This study aimed to evaluate the milk clotting capacity (MCA), and caseinolytic activity (CA) of crude coagulant from stomachs adult rabbits (RC), their influence on composition, proteolysis, texture type Prato cheese. We tested two ways for salting abomasum three levels pH times enzyme activation. The presence enzymes in RC was assayed by SDS-PAGE. effects milk’s temperature RC’s water-holding...

p94 (also called calpain 3) is the skeletal muscle-specific calpain and is considered to be a "modulator protease" in various cellular processes. Analysis of p94 at the protein level is an urgent issue because the loss of p94 protease activity causes limb-girdle muscular dystrophy type 2A. In this study, we enzymatically characterized one alternatively spliced variant of p94, p94:exons 6(-)15(-...
