| Primary Identifier | IPR022426 | Type | Family |
| Short Name | FliI_clade3 |
| description | This family represent the bacterial flagellum-specific ATP synthase, FliI, which is needed for flagellar assembly. FliI is part of the flagellar type III protein export apparatus acting as an ATPase to drive protein export for flagellar biosynthesis [, , ]. When FliI is not engaged in flagellar protein export, FliH, another flagellar type III protein export apparatus protein, functions as a negative regulator to prevent FliI from hydrolysing ATP []. It has been suggested that the N terminus of FliI interacts with FliH, while the the C-terminal domain of FliI possesses the ATPase catalytic function [, ]. The structure of the N-terminally truncated variant of FliI lacking the first 18 residues have been determinded [].This entry represents one (of three) segment of the FliI family tree. |
