Biosynthesis of 2-deoxystreptamine-containing antibiotics in Streptoalloteichus hindustanus JCM 3268: characterization of 2-deoxy-scyllo-inosose synthase.

A part of the new biosynthetic gene cluster for 2-deoxystreptamine-containing antibiotics was identified from Streptoalloteichus hindustanus. The alloH gene in the gene cluster was deduced to encode 2-deoxy-scyllo-inosose synthase and the expressed protein AlloH was confirmed to have this enzyme activity. Furthermore, biochemical properties of AlloH were studied.
