Function

[CHER1_PSEAE] Methylation of the membrane-bound methyl-accepting chemotaxis proteins (MCP) to form gamma-glutamyl methyl ester residues in MCP. [CDGBP_PSEAE] Binds the second messenger bis-(3'-5') cyclic dimeric guanosine monophosphate (c-di-GMP). Can bind two c-di-GMP molecules per monomer. May play a role in bacterial second-messenger regulated processes. Binding to c-di-GMP induces a conformational change of the C- and N-termini resulting in the exposure of a highly negative surface on one side of the protein to a possible effector protein.^[1] ^[2] ^[3]

Publication Abstract from PubMed

The bacterial second messenger cyclic diguanylate monophosphate (c-di-GMP) mediates multiple aspects of bacterial physiology through binding to various effectors. In some cases, these effectors are single-domain proteins which only contain a PilZ domain. It remains largely unknown how single-domain PilZ proteins function and regulate their downstream targets. Recently, a single-domain PilZ protein, MapZ (PA4608), was identified to inhibit the activity of the methyltransferase CheR1. Here, crystal structures of the C-terminal domain of CheR1 containing SAH and of CheR1 in complex with c-di-GMP-bound MapZ are reported. It was observed that the binding site of MapZ in CheR1 partially overlaps with the SAH/SAM-binding pocket. Consequently, binding of MapZ blocks SAH/SAM binding. This provides direct structural evidence on the mechanism of inhibition of CheR1 by MapZ in the presence of c-di-GMP.

Structural basis for the regulation of chemotaxis by MapZ in the presence of c-di-GMP.,Zhu Y, Yuan Z, Gu L Acta Crystallogr D Struct Biol. 2017 Aug 1;73(Pt 8):683-691. doi:, 10.1107/S2059798317009998. Epub 2017 Jul 28. PMID:28777083^[4]
