Short name: ABC_transptr_permease_BtuC

Overlapping homologous superfamilies

Family relationships


This entry represents a family of ABC transporter permease proteins. It includes the vitamin B12 import system permease protein BtuC, and the Fe(3+) dicitrate transport system permease proteins FecC and FecD, among many others.

BtuC is a component of the ABC transporter complex BtuCD, which facilitates uptake of vitamin B(12) into the cytoplasm of Escherichia coli [PMID: 16331991].

FecC and FecD are components of of the fec operon, a Periplasmic-Binding-Protein (PBP)-dependent transport system for ferric dicitrate in Escherichia coli [PMID: 2651410]. FecC and FecD exhibit homology to each other and are localized in the cytoplasmic membrane.
