Intro

Diguanylate cyclase PleD (1w25)

Drag the structure with the mouse to rotate


from Caulobacter crescentus is a response regulator with an unorthodox catalytic, diguanylate cyclase, output domain. It is composed of a canonical CheY-like response regulator receiver () domain, a Rec-like () adaptor domain, and a C-terminal domain that confers the catalytic acitvity.



The GGDEF domain is named after the highly conserved (in PleD it is GGEEF) that locates to a β-hairpin.
