Restriction endonuclease cleavage maps of five DNA fragments carrying genes for neomycin phosphotransferase and neomycin acetyltransferase (from Streptomyces fradiae), viomycin phosphotransferase (from S. vinaceus), and ribosomal methylases determining resistance to thiostrepton (from S. azureus) and MLS antibiotics (from S. erythreus) are described, together with a map for the SLP1.2 Streptomyces plasmid used to isolate the fragments. Construction of a versatile Streptomyces cloning vector (pIJ61) is reported. pIJ61 carries neomycin phosphotransferase and thiostrepton resistance genes and has unique BamHI and PstI sites which will allow clone recognition by insertional inactivation of neomycin resistance; cloning sites for several other endonucleases are also present. pIJ28, a shuttle vector for Streptomyces and E. coli, carries neomycin resistance and the SLP1.2 and pBR322 replicons.
