Publication Abstract from PubMed

Recent studies of signal transduction in bacteria have revealed a unique second messenger, bis-(3'-5')-cyclic dimeric GMP (c-di-GMP), which regulates transitions between motile states and sessile states, such as biofilms. C-di-GMP is synthesized from two GTP molecules by diguanylate cyclases (DGC). The catalytic activity of DGCs depends on a conserved GG(D/E)EF domain, usually part of a larger multi-domain protein organization. The domains other than the GG(D/E)EF domain often control DGC activation. This paper presents the 1.83 A crystal structure of an isolated catalytically competent GG(D/E)EF domain from the A1U3W3_MARAV protein from Marinobacter aquaeolei. Co-crystallization with GTP resulted in enzymatic synthesis of c-di-GMP. Comparison with previously solved DGC structures shows a similar orientation of c-di-GMP bound to an allosteric regulatory site mediating feedback inhibition of the enzyme. Biosynthesis of c-di-GMP in the crystallization reaction establishes that the enzymatic activity of this DGC domain does not require interaction with regulatory domains.
