The lincomycin biosynthetic gene lmbX was deleted in Streptomyces lincolnensis ATCC 25466 that led to abolition of lincomycin production. Complementation experiments proved the blockage in biosynthesis of lincomycin precursor 4-propyl-L proline. Feeding this mutant strain with precursor derivatives resulted in production of 4-butyl-4-depropyllincomycin and 4-pentyl-4-depropyllincomycin in high titers and without lincomycin contamination. Moreover, 4-pentyl-4-depropyllincomycin was found to be more active than lincomycin against clinical Staphylococcus isolates with genes determining low-level lincosamide resistance
