wild-type ornA and the ornA (D130A) point mutant are placed under the control of the strong, constitutive ermE promoter in the hygromycin-resistant, attP-integrative vector pIJ10275. The resultant plasmids (pJS93 and pJS94) introduced into Streptomyces coelicolor J3411 (DELTAornA::apr) by conjugation with Escherichia coli strain ET12567 (pUZ8002) to yield Streptomyces coelicolor J3411 (pJS93) and Streptomyces coelicolor J3411 (pJS94)
