Any process that initiates the activity of the inactive enzyme cysteine-type endopeptidase.

activation of metacaspase activity

This term should be used to annotate gene products within the context of cellular processes other than apoptotic cell death (e.g., cell cycle arrest). To annotate gene products involved in activation of cysteine-type endopeptidases where the activation results in apoptotic process, please use the more granular term GO:0006919.
