General Information
Term cobalamin transport complex ID (Ontology) GO:1990191 (Gene Ontology)
Definition Protein complex facilitating ATP-dependent cobalamin (vitamin B12) transport through inner cell membrane (periplasm to cytoplasm) in Gram-negative bacteria. In E. coli the system is composed of a periplasmic cobalamin-binding protein (BtuF), an integral membrane homodimer, BtuC, and a cytoplasmic ATP-binding homodimer BtuD.[ PubMed:22569249 ]
Also Known As "BtuCDF complex" ; "cobalamin-transporting BtuCDF complex" ; "vitamin B12 transport complex" (for all, see Synonyms field below)
