title: Function of lanGT3, a glycosyltransferase gene involved in landomycin A biosynthesis.
abstract: The glycosyltransferase gene lanGT3, involved in the biosynthesis of the angucyclic antibiotic landomycin A, has been characterised by targeted gene deletion. A lanGT3 mutant was shown to produce landomycin E, which consists of a trisaccharide side chain attached to the polyketide moiety. Expression of lanGT3 in the mutant restored landomycin A production. Our results indicate that LanGT3 is responsible for the transfer of the fourth sugar during landomycin A biosynthesis.
