UniProt functional annotation for P37028

UniProt code: P37028.

Organism: Escherichia coli (strain K12).
Taxonomy: Bacteria; Proteobacteria; Gammaproteobacteria; Enterobacterales; Enterobacteriaceae; Escherichia.
 
Function: Part of the ABC transporter complex BtuCDF involved in vitamin B12 import. Binds vitamin B12 and delivers it to the periplasmic surface of BtuC. {ECO:0000255|HAMAP-Rule:MF_01000, ECO:0000269|PubMed:11790740}.
 
Subunit: The complex is composed of two ATP-binding proteins (BtuD), two transmembrane proteins (BtuC) and a solute-binding protein (BtuF). {ECO:0000255|HAMAP-Rule:MF_01000, ECO:0000269|PubMed:12468528, ECO:0000269|PubMed:12475936}.
Subcellular location: Periplasm {ECO:0000255|HAMAP-Rule:MF_01000, ECO:0000269|PubMed:11790740}.
Miscellaneous: Vitamin B12 is bound in a deep cleft formed at the interface between the two lobes of BtuF. {ECO:0000269|PubMed:12475936}.
Similarity: Belongs to the BtuF family. {ECO:0000255|HAMAP- Rule:MF_01000, ECO:0000305}.
