Enzyme Information

3.1.4.59

Cyclic-di-AMP phosphodiesterase.

based on mapping to UniProt A4ITV2

Cyclic di-3',5'-adenylate + H(2)O = 5'-O-phosphonoadenylyl-(3'->5')- adenosine.

-!- 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 Mn(2+) and is inhibited by pApA.
