Patent number: 5879903Abstract: Selection of Streptomyces viridochromogenes DSM 4112 for resistance to phosphinothricyl-alanyl-alanine (PTT) results in PTT-resistance selectants. The DNA fragment which carries the phosphinothricin(PTC)-resistance gene is obtained from the total DNA of these selectants by cutting with BamHI, cloning of a fragment 4.0 kb in size, and selection for PTT resistance. This gene is suitable for the production of PTC-resistant plants, and as a resistance marker and for the selective N-acetylation of the L-form of racemic PTC.Type: GrantFiled: June 7, 1995Date of Patent: March 9, 1999Assignee: Hoechst AktiengesellschaftInventors: Eckhard Strauch, Wolfgang Wohlleben, Walter Arnold, Renate Alijah, Alfred Puhler, Gerhard Wohner, Rudiger Marquardt, Susanne Grabley, Dieter Brauer, Klaus Bartsch

Patent number: 4965207Abstract: Intensely crimson colonies are obtained from Streptomyces coelicolor DSM 3030 by total digestion of the total DNA, cloning into a suitable vector, and transformation of Streptomyces lividans. Re-isolation of the plasmid DNA and cutting with BamHI results in fragments about 3.4 to 9 kb in length, on which is located the gene which determines production of the coloring agent.
