CdAMP is a family of bacterial cyclic-di-AMP receptor proteins. Cyclic-di-AMP (c-di-AMP) is a bacterial secondary messenger involved in various processes, including sensing of DNA-integrity, cell wall metabolism and potassium transport. CdAMP_rec has a ferredoxin-like fold and is structurally related to Pii-signal transduction proteins [1].	Domain
