[Activity of cathepsin B and serine trypsin-like peptide hydrolases in human kidney extracts]. 1986

A A Zhloba, and I G Shcherbak

A potentiality to use the available substrates BAPNA and BAME was studied in estimation of activities of cathepsin B and other trypsin-like hydrolases in extracts of human kidney cortex. In these extracts the BAME-hydrolyzing activity of cathepsin B was difficult if impossible to detect due to high level of attendant non-thiol esterases. At the same time, BAPNA might be used for this purpose as a substrate in estimation of cathepsin B- and trypsin-like peptide hydrolase activities in biopsies of human kidney.

D002401	Cathepsin B	A lysosomal cysteine proteinase with a specificity similar to that of PAPAIN. The enzyme is present in a variety of tissues and is important in many physiological and pathological processes. In pathology, cathepsin B has been found to be involved in DEMYELINATION; EMPHYSEMA; RHEUMATOID ARTHRITIS, and NEOPLASM INVASIVENESS.

D002403	Cathepsins	A group of lysosomal proteinases or endopeptidases found in aqueous extracts of a variety of animal tissues. They function optimally within an acidic pH range. The cathepsins occur as a variety of enzyme subtypes including SERINE PROTEASES; ASPARTIC PROTEINASES; and CYSTEINE PROTEASES.	Cathepsin
