cysteine-type endopeptidase activity obsolete cysteine-type endopeptidase activity involved in apoptotic process https://github.com/geneontology/go-ontology/issues/28468 true metacaspase activity The reason for obsoletion is that this term represents a GO-CAM model. OBSOLETE. Catalysis of the hydrolysis of internal, alpha-peptide bonds in a polypeptide chain by a mechanism in which the sulfhydryl group of a cysteine residue at the active center acts as a nucleophile, and contributing to the apoptotic process. molecular_function 2011-09-09T10:21:56Z GO:0097153 caspase activity pr
