A microassay for proteolytic activity
Analytical Biochemistry, 1991A quantitative procedure for measuring proteolytic activity, utilizing azoalbumin as substrate, has been developed for use in microtiter plates. An enzyme-linked immunosorbent assay reader is used to measure absorbance. The procedure is sensitive, as well as being both rapid and economical.

The Proteolytic Activity in Brain
Archives Internationales de Physiologie et de Biochimie, 1966AbstractThe acid proteinase activity in human and steer brain areas has been determined. Grey matter contains more acid proteinase activity than white matter. A major portion of the activity resides in the soluble fraction of the cell. The Mn++-stimulated aminopeptidase activity and dipeptidase activity in human astrocytoma tissue homogenates are ...

Metallo‐Organozymes with Specific Proteolytic Activity
Chemistry – A European Journal, 2018AbstractMetallopeptides that show efficiency and selectivity in peptide bond cleavage in water at room temperature and neutral conditions are presented. These small and versatile organozymes take advantage of metal‐coordinating building blocks that are strategically positioned centrally in a peptide backbone or in a peptide macrocycle.

Activities of proteolytic enzymes
2011Proteases, also known as proteinases or proteolytic enzymes, are a large group of hydrolases that catalyze the cleavage of peptide bonds in proteins to produce peptides and/or amino acids. Classification of proteolytic enzymes is based on three major criteria: type of reaction catalyzed, functional group of the active site, and type of molecular ...

Extracellular proteolytic activity ofCryptococcus neoformans
Mycopathologia, 1994Eight strains of Cryptococcus neoformans var. neoformans isolated from AIDS patients in the Infectious Disease Institute, University of Turin, Italy, were examined for growth and extracellular proteolytic activity in culture with solid and liquid media. All of the strains grew well on Yeast Carbon Base (YCB) agar medium supplemented with both 0.1% (w/v)

PROTEOLYTIC ACTIVITIES THAT MEDIATE APOPTOSIS
Annual Review of Physiology, 1998▪ Abstract Since the discovery that cells can activate their own suicide program, investigators have attempted to determine whether the events that are associated with this form of cell death are genetically determined. The discovery that the ced-3 gene of Caenorhabditis elegans encodes a cysteine protease essential for developmentally regulated ...

Proteolytic and non-proteolytic activation of human neutrophil progelatinase B
Biochimica et Biophysica Acta (BBA) - Protein Structure and Molecular Enzymology, 1995The activation of human neutrophil progelatinase B (pro-HNG) by a variety of proteolytic and non-proteolytic activators has been investigated. A quantitative comparison of the activation efficiencies of treatments previously reported to activate pro-HNG or the related gelatinase B species produced by other cells demonstrates that stromelysin and ...

Endogenous proteolytic activity of chromatin
1977Chromatin from rat liver and Ehrlich ascites tumor (EAT) was isolated by two different procedures and the chromatin preparations were incubated at 37 degrees C. To follow the proteolysis at 0, 4, 8, and 24 hrs, aliquots were taken and analysed by SDS polyacrylamide gel electrophoresis. Although there were some differences in the proteolytic activity of

Myxobacterial slime and proteolytic activity
Archives of Microbiology, 1978An extracellular protein-polysaccharide-lipide (PPL) complex from exponentially growing cultures of Myxococcus virescens was purified by phosphate precipitation and gel chromatography. The high molecular weight slime polymer appeared homogenous upon isoelectric focusing.
