Folate-biopterin transporter (IPR004324)

Short name: FBT

Overlapping homologous superfamilies

Family relationships


This entry includes folate-biopterin transporters (FBTs) from blue-green algae and plants, including Slr0642 protein from Synechocystis and its plastidial orthologue At2g32040 from Arabidopsis [PMID: 19923217]. Both Slr0642 protein and At2g32040 mediate folate monoglutamate transport involved in tetrahydrofolate biosynthesis. However, this entry also includes 7 other Arabidopsis FBT proteins that lack conserved critical residues and may not have folate or pterin transport activity [PMID: 19923217].
