چکیده

An extracellular protease of Staphylococcus aureus, strain V8, previously shown to cleave specifically the peptide bonds on the carboxyl-terminal side of either aspartate or glutamate residues in phosphate buffer (pH 7.8) hydrolyzes only glutamoyl bonds in either ammonium bicarbonate (pH 7.8) or ammonium acetate (pH 4.0). Of all aspartoyl bonds tested, only the Asp-Gly linkage is cleaved at a detectable rate. The staphylococcal protease hydrolyzes all of the seventeen different glutamoyl bonds studied, although those involving hydrophobic aminoacid residues with bulky side chains are cleaved at a lower rate.

Isolation and amino acid sequence of a neurotoxic phospholipase A from the venom of the Australian tiger snake Notechis scutatus scutatus.

The complete amino acid sequence of notechis 5, a neurotoxic phospholipase A from the venom of Notechis scutatus scutatus (Australian tiger snake), has been elucidated. The main fragmentation of the 119-residue peptide chain was accomplished by digesting the reduced and S-carboxymethylated derivative of the protein with a staphylococcal protease specific for glutamoyl bonds. Tryptic peptides we...

Role of a protease in natural activation of Clostridium botulinum neurotoxin.

All tested proteolytic Clostridium botulinum type A, B, and F strains and certain non-proteolytic B and F cultures produced a protease having trypsin-like substrate specificity; none of the tested type E (non-proteolytic) strains produced the enzyme. Progenitor toxin (toxic form whose specific toxicity is increased by treatment with trypsin) was found in culture fluid concentrates of all strain...

Evaluation of Comparative Total Proteolytic Activity in Plant Lattices

Proteases catalyze the hydrolysis of a peptide bond of a protein; they are widely distributed in nature. They perform various biological functions in plants and particularly in humans they participate in zymogen activation, fibrinolysis, complement activation, blood coagulation and digestion process. Objectives: The present study focused on evaluation of in vitro total proteolytic activity from...

Study on Activity and Stability of Proteases from Bacillus Sp. Produced by Submerged Fermentation

Objective: Investigations were carried out to isolate bacteria from saline-alkali soils and determined optimized alkaline protease activity and stability produced by a wild strain of bacillus sp. in submerged fermentation (SMF). Methods: Optimum temperature for enzyme activity in the crude extract was 40 ◦C at a pH between 8.0 and 9.0. The studies on pH stability showed that the enzyme...
