Proteolytic activity of viper venoms

Applied Biochemistry and Microbiology, 2000
Proteolytic activities of venoms of vipers kept in a serpentarium for three years or captured in various environmental regions were estimated. Gurza venom contained considerable amounts of protein (830-930 micrograms/mg venom) and displayed a high proteolytic activity by tyrosine (80-140 micrograms/min mg protein).

Proteolytic Activity in CSF

1978
Proteolytic enzyme activity, present at both acid and neutral pH values, in cerebrospinal fluid, can be measured by a sensitive assay, which monitors the rate of 125I-basic protein breakdown on polyacrylamide gel electrophoresis. CSF cellular neutral proteinase and supernatant acid proteinase are increased in acute multiple sclerosis and in CNS ...

Proteolytic activities in Bacillus

Current Opinion in Biotechnology, 1991
Major advances have been made in understanding the regulation of expression of Bacillus subtilis protease genes. A phosphorelay mechanism as well as a two-component regulatory system allow conditions of the growth medium to be transmitted to the gene level resulting in expression of extracellular protease genes.

THE PROTEOLYTIC ACTIVITY OF INSULIN

Canadian Journal of Biochemistry, 1967
The action of insulin on hemoglobin at pH 7.5 was studied. Four different methods were used to determine the degree of proteolysis. After mixtures of hemoglobin and insulin were incubated for 2 hours, very little amino acid or peptide material was liberated from the proteins.

Regulation of deubiquitinase proteolytic activity

Current Opinion in Structural Biology, 2013
Deubiquitinases (DUBs) are proteolytic enzymes whose function is to oppose the process of the conjugation of ubiquitin to a specific substrate. This task is accomplished through an enzymatic cascade involving E1, E2, and E3 enzymes, which collectively produce a product that is either monoubiquitinated, or polyubiquitinated with multiple single ...

Proteolytic activity of chorioamniotic membranes

Biochemical Medicine, 1982
Abstract The various forms of proteinases in the chorioamniotic membranes (CAM) have been investigated utilizing specific and nonspecific substrates and group-specific inhibitors. We have demonstrated the presence of acid, serine, thiol, and metalloproteinases in CAM.

Proteolytic activity of bovine lactoferrin

Biometals, 2004
Bovine lactoferrin catalyzes the hydrolysis of synthetic substrates (i.e., Z-aminoacyl-7-amido-4-methylcoumarin). Values of Km and kcat for the bovine lactoferrin catalyzed hydrolysis of Z-Phe-Arg-7-amido-4-methylcoumarin are 50 microM and 0.03 s(-1), respectively, the optimum pH value is 7.5 at 25 degrees C.

Proteolytic Activities of Mycoplasma Salivarium

Advances in Dental Research, 1988
Proteolytic activity was demonstrated in ATCC 23064 and oral isolates (more than 100 strains) of My coplasma salivarium and was suggested to be due to aminopeptidase, some other metalloproteinases, and serine proteinases. An aminopeptidase and a carboxypeptidase were purified from cell membranes of the organism and characterized.

Plasma Proteolytic Activity following Burns

The Journal of Trauma: Injury, Infection, and Critical Care, 1988
Because a number of metabolic events which are triggered by proteolysis in the bloodstream are activated following trauma, net proteolytic activity (P.A.) in the plasma of 37 pediatric burned patients was measured. The P.A. assay involved incubating plasma with a radioiodinated protein substrate and counting the isotopic activity of the hydrolyzed ...

Proteolytic activity in ptarmigan muscle

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1976
Abstract 1. 1. The activities of three acid hydrolases, β-glucuronidase, β-acetylglucosaminidase, and cathepsin D were measured in homogenates from liver and pectoral muscle of the willow ptarmigan and chicken. 2. 2. Pectoral muscle from ptarmigan had relatively high cathepsin D activity.
