Description
  • Ve shluku genů kódujících biosyntézu linkomycinu bylo zjištěno 27 otevřených čtecích rámců s biosyntetickou či regulační funkcí a 3 rezistenční geny. Ze srovnání chemické struktury linkomycinu a celesticetinu vyplývá, že v biosyntetické dráze chybí dráha vedoucí k propylprolinu a prolin je přímo substrátem kondenzační reakce. Část biosyntetické dráhy zahrnující přeměnu L-tyrosinu na propyl-L-prolin by měla být přítomna v biosyntetické dráze funkčně odlišných antramycinových antibiotik. Byla zjišťováno rozvržení genu linkomycinového biosyntetického shluku do transkripčních jednotek. Dále byla na základě sekvence tohoto shluku navržena sada sond, pomocí nichž byly vyhlédávány analogy genů v producentech celesticetinu Streptomyces caelestis a antramycinů Streptomyces refuineus, Streptomyces albus and Streptosporangium sibiricum.

  • Lincomycin, produced by Streptomyces lincolnensis, is important, clinically used antibiotic. Its gene cluster consists of twenty-seven putative open reading frames with biosynthetic or regulatory functions and three resistance genes. Comparison of the chemical structure of the lincomycin and celesticetin indicates, that in the biosynthesis of celesticetin the whole propylproline branch is absent and proline is substrate of the penultimate step of biosynthesis, the condensation reaction. Second part of biosynthetic pathway including conversion of L-tyrosine to L-proline should be involved in the biosynthesis of functionally different anthramycin antibiotics. Thus it appears, that genetic information on lincomycin and anthramycin biosynthesis must also share common elements (genes), both biosynthetic and regulatory. The organization of transcription units was found. The analysis of the lincomycin biosynthetic gene transcripts in various cultivation stages revealed the genes with putat...
