46(6):506-14.
PMID: 10913971
Fatty-acid biosynthesis by a branched-chain alpha-keto acid dehydrogenase (bkd) mutant of Streptomyces avermitilis was analyzed. This mutant is unable to produce the appropriate precursors of branched-chain fatty acid (BCFA) biosynthesis,...

. 1992 Feb;
70(1):9-13.
PMID: 1577258
Streptomyces avermitilis has the ability to synthesize a diffusible, brown, melanin-like pigment, a common property among many Streptomyces species. A region of the S. avermitilis chromosome involved in the production...

PMID: 2026560
The eight natural avermectins produced by Streptomyces avermitilis have the carbon skeleton of either isobutyric or S-2-methylbutyric acid incorporated into their structures. A mutant of S. avermitilis has been isolated...

PMID: 6392022
The speA, speB and speC genes, which code for arginine decarboxylase (ADCase), agmatine ureohydrolase (AUHase) and ornithine decarboxylase (ODCase), respectively, and the metK gene, which encodes methionine adenosyltransferase (MATase), have...
