YbgCis believed to have first appeared in the Tol complex with the separation of the δε proteobacteria from the αβγ proteobacteria[1].
StructureStructure
YbgC is a cytoplasmic protein in the Tol-Pal complex[2]. In Helicobacter pylori, the protein is part of a 'hot-dog' family of proteins, with an epsilongamma tetrameric arrangement[3].
FunctionFunction
The protein displays thioesterase activity towards acyl-CoA thioesters[4], and has a strong sequence conservation with its active site residues with other proteins of a similar function[5] for example with the Pseudonomas sp. strain CBS3 4-hydroxybenzoyl-CoA thioesterase[6].
However, its role within the Tol complex itself remains unknown, although it may be involved in the acetylation of another protein within the complex, with the role of an activity-regulator[1]. It is also thought to be involved in the cell division complex of Tol-Pal[7].
