Chains	Enzyme Name	Description	Catalytic Residues
A	ADP-ribose diphosphatase M-CSA #823	The ADP-ribose-specific Nudix hydrolase from Mycobacterium tuberculosis (MT-ADPRase or ADPR pyrophosphatase) is part of the family of Nudix hydrolases with the characteristic Nudix box that catalyse hydrolysis of nucleoside diphosphate derivatives. Divalent magnesium or manganese ions are required for activity. Differences in binding sites of the M. tuberculosis enzyme and the human homologue suggest a possible target for antituberculosis drug treatment.
