Folate-biopterin transporter family

The folate-biopterin transporter (FBT) family (TC# 2.A.71) is a distant family within the major facilitator superfamily, most closely related to drug resistance permeases. Proteins of the FBT family are reported to contain about 480 to 650 amino acyl residues. All probably have 12 transmembrane α-helical segments (TMSs). They may function by H+ symport.
