It preferentially acts on substrates in which the lipid-bearing Gal residue is connected to the sequence by a (1->6)-beta-glycosidic linkage. The preferential formation of alternating (1->6)-beta-Galf and (1->5)-beta-Galf residues arises not from substrate binding but during catalytic processive polymerization Mycobacterium tuberculosis ? - - 89 2.4.1.288 additional information GlfT2 mediates synthesis of the galactan polymer, which contains between 20 and 40 D-galactofuranose residues connected by alternating beta-D-galactofuranosyl-(1->5)-D-galactofuranose and beta-D-galactofuranosyl-(1->6)-D-galactofuranose linkages.
