Dihydrochalcomycin Production and Glycosyltransferase from Streptomyces SP. KCTC 0041BP.
The dihydrochalcomycin (GERI) synthetic gene cluster from Streptomyces sp. KCTC 0041BP has been isolated. Two open reading frames (ORFs), designated gerT1 and gerT2 as glycosyltransferase genes, has been identified by sequence analysis. GerT1 encodes for the protein function as dTDP-deoxyallosyltransferase and it is responsible to the attachment of dTDP-allose to the macrolide ring. Similarly, gerT2 encodes for peptide named as dTDP-chacosyltransferase which can transfers the dTDP-4,6-dideoxyglucose to macrolactone core. During process of compound isolation, a new compound has been isolated with molecular weight m/z 755 [M+Na+]. This compound could be the dihydrochalcomycin derivative. The compound has been shown the same antibacterial activity as GERI compound.
