| + | Bis-(3',5') cyclic di-guanylate (c-di-GMP) is a key bacterial second messenger that is implicated in the regulation of many crucial processes that include biofilm formation, motility and virulence. Cellular levels of c-di-GMP are controlled through synthesis by GGDEF domain diguanylate cyclases and degradation by two classes of phosphodiesterase with EAL or HD-GYP domains. Here, we have determined the structure of an enzymatically active HD-GYP domain protein from Persephonella marina (PmGH) alone, in complex with substrate (c-di-GMP) and final reaction product (GMP). The structures reveal a novel trinuclear iron binding site, which is implicated in catalysis and identify residues involved in recognition of c-di-GMP. This structure completes the picture of all domains involved in c-di-GMP metabolism and reveals that the HD-GYP family splits into two distinct subgroups containing bi- and trinuclear metal centres. | ||
