Spiramycin
biosynthesis in Streptomyces ambofaciens was stimulated in the presence of valine or by sequential addition of some short-chain fatty acids to a culture medium containing an ammonium salt as source of nitrogen. Acetate kinase and
acetyl-CoA carboxylase
, enzymes that catalysed the formation of precursors of spiramycin biosynthesis (acetyl-CoA and malonyl-CoA), were detected during the active growth and antibiotic production phases. In this latter phase a higher level of
acetyl-CoA carboxylase
activity was observed with valine (1.02 mumol.min-1.mg protein-1) than with ammonium (0.05 mumol.min-1.mg protein-1) as nitrogen source, while the evolution and the level of acetate kinase activity were the same in both media. Successive addition of acetate and isobutyrate stimulated highly and weakly the
acetyl-CoA carboxylase
and acetate kinase activity, respectively.
