| Type: | Domain | Name: | GGDEF domain |
| Description: | The GGDEF domain, which has been named after the conserved central sequence pattern GG[DE][DE]F is widespread in prokaryotes. It is typically present inmultidomain proteins containing regulatory domains of signaling pathways or protein-protein or protein-ligand interaction modules, such as the responseregulatory domain, the PAS/PAC domain, the HAMP domain, the GAF domain, the FHA domain or the TPR repeat. However a few single-domain proteins are also known. The GGDEF domain is involved in signal transduction and is likely to catalyze synthesis or hydrolysis of cyclic diguanylate (c-diGMP, bis(3',5')-cyclic diguanylic acid), an effector molecule that consists of two cGMP moieties bound head-to-tail [, , ].Structural studies of PleD from Caulobacter crescentusshow that this domain forms a five-stranded beta sheet surrounded by helices, similar to the catalytic core of adenylate cyclase []. | Short Name: | GGDEF_dom |
