Elongation occurs by addition of D-galactofuranose residues from UDP-alpha-D-galactofuranose to the nonreducing end of a lipid-linked acceptor Mycobacterium tuberculosis ? - ? 89 2.4.1.288 additional information no activity with 4-phenoxy-but-2-enyl beta-D-galactofuranosyl-(1->6)-beta-D-galactofuranoside Mycobacterium tuberculosis ? - ? 89 2.4.1.288 additional information octyl alpha-L-rhamnopyranosyl-(1->3)-2-acetamido-2-deoxy-alpha-D-glucopyranoside and octyl alpha-D-galactofuranosyl-(1->4)-alpha-L-rhamnopyranosyl-(1->3)-2-acetamido-2-deoxy-alpha-D-glucopyranoside are no effective substrates Mycolicibacterium smegmatis ? - ? 89 2.4.1.288 additional information GlfT2 is promiscuous in its substrate preferences. It preferentially acts on substrates in which the lipid-bearing Gal residue is connected to the sequence by a (1->)-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 among hexoses, monosaccharides, 4-nitrophenyl-furanoses, 4-nitorphenyl-hexoses and disaccharides tested, only methyl alpha-D-mannopyrannoside efficiently reacts as an acceptor.
