MeSH definition : 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.;
