Accepted name: cyclic-di-AMP phosphodiesterase
Reaction: cyclic di-3′,5′-adenylate + H2O = 5′-O-phosphonoadenylyl-(3′→5′)-adenosine

Glossary: cyclic di-3′,5′-adenylate = cyclic bis(3′→5′)diadenylate
5′-O-phosphonoadenylyl-(3′→5′)-adenosine = pApA
Other name(s): gdpP (gene name)
Systematic name: cyclic bis(3′→5′)diadenylate 3′-adenylylhydrolase
Comments: The enzyme, described from Gram-positive bacteria, degrades the second messenger cyclic di-3′,5′-adenylate. It is a membrane-bound protein that contains a cytoplasmic facing Per-Arnt-Sim (PAS) domain, a modified GGDEF domain, and a DHH/DHHA1 domain, which confers the phosphodiesterase activity. Activity requires Mn2+ and is inhibited by pApA.
