Protein
Galactofuranosyltransferase GlfT1
Organism
Mycobacterium smegmatis (strain ATCC 700084 / mc(2)155)
Function
Involved in the biosynthesis of the arabinogalactan (AG) region of the mycolylarabinogalactan-peptidoglycan (mAGP) complex, an essential component of the mycobacterial cell wall. Catalyzes the transfer of the first two galactofuranosyl (Galf) units from UDP-galactofuranose (UDP-Galf) onto the rhamnosyl-GlcNAc-diphospho-decaprenol (Rha-GlcNAc-PP-C50) acceptor, yielding galactofuranosyl-galactofuranosyl-rhamnosyl-GlcNAc-diphospho-decaprenol (Galf-Galf-Rha-GlcNAc-PP-C50). Thus, GlfT1 is the initiator of galactan synthesis, while GlfT2 continues with the subsequent polymerization events.
Similarity
Belongs to the glycosyltransferase 2 family.
