Previous findings suggested that cyclic AMP was involved in the regulation of ilvB(AHASI) only and that ilvG (AHASII) and ilvHI (AHASIII) were not controlled by this nucleotide. In this study, derepression patterns of total AHAS activities (ilvB and ilvHI) in adenyl cyclasenegative strains (i.e. cya
The biosynthetic acetohydroxy acid synthase activities of E. coli K 12 are encoded by three genetic loci namely, ilvB (acetohydroxy acid synthase I), ilvG (acetohydroxy acid synthase II) and ilvHI (acetohydroxy acid synthase III). The previously reported involvement of cyclic AMP in the regulation o
