In Bacillus species this highly conserved region of the YkuI protein lies immediately downstream of the EAL (diguanylate cyclase/phosphodiesterase domain 2) Pfam:PF00563 domain so that together they form a monomer which dimerises for its enzymatic action. The region contains three alpha helices and five beta strands and is the C-terminal half of the structure.	Domain

This domain is found in diverse bacterial signaling proteins. It is called EAL after its conserved residues. The EAL domain is a good candidate for a diguanylate phosphodiesterase function [1]. The domain contains many conserved acidic residues that could participate in metal binding and might form the phosphodiesterase active site [1].	Domain
