Analysis of the gene lmbX included propylproline biosynthesis
 Smutná, Yvona ; Najmanová, Lucie (referee)
Analysis of the gene lmbX included propylproline biosynthesis Abstract Lincomycin and its derivates are potent antibiotics used in human and veterinary medicine, they are antibiotics exibiting biological activity against Gram-positive bacteria. Lincomycin molecule is composed of two amide-bonded subunits, methylthiolincosamide and propylproline. The aim of the study was to assign the gene lmbX to the propylproline biosynthesis based on gene inactivation experiments. The gene lmbX was inactivated by help of REDIRECT technology: PCR targeting system in Streptomyces coelicolor. The respective S. lincolnensis inactivants were checked for lincomycin production by means of biological test and UPLC analysis of their fermentation broth and then exploited in feeding experiments. It was found, that inactivation of the lmbX gene caused suppression of the lincomycin production which was restored upon PPL feeding therefore the respective gene was assigned to reaction of PPL branch of LM biosynthesis.
