SufI Protein from Escherichia Coli
Structural highlights
FunctionFTSP_ECOLI Cell division protein that is required for growth during stress conditions. May be involved in protecting or stabilizing the divisomal assembly under conditions of stress.[HAMAP-Rule:MF_00915][1] Evolutionary Conservation Check, as determined by ConSurfDB.

Publication Abstract from PubMedThe Escherichia coli protein SufI (FtsP) has recently been proposed to be a component of the cell division apparatus. The SufI protein is also in widespread experimental use as a model substrate in studies of the Tat (twin arginine translocation) protein transport system. We have used SufI-GFP (green fluorescent protein) fusions to show that SufI localizes to the septal ring in the dividing cell. We have also determined the structure of SufI by X-ray crystallography to a resolution of 1.9 A. SufI is structurally related to the multicopper oxidase superfamily but lacks metal cofactors. The structure of SufI suggests it serves a scaffolding rather than an enzymatic role in the septal ring and reveals regions of the protein likely to be involved in the protein-protein interactions required to assemble SufI at the septal ring. The Escherichia coli Cell Division Protein and Model Tat Substrate SufI (FtsP) Localizes to the Septal Ring and Has a Multicopper Oxidase-Like Structure.,Tarry M, Arends SJ, Roversi P, Piette E, Sargent F, Berks BC, Weiss DS, Lea SM J Mol Biol. 2008 Dec 25.
