LITERATURE
formation of the enzyme components of the acetoin dehydrogenase enzyme system E1, i.e. acetoin:2,6-dichlorophenolindophenol oxidoreductase Ao:DCPIP OR,, E2, i.e. dihydrolipoamide acetyltransferase DHLTA, and E3, i.e. dihydrolipoamide dehydrogenase DHLDH, are induced during growth on acetoin
-
the enzymes Ao:DCPIP OR, dihydrolipoamide dehydrogenase, and dihydrolipoamide acetyltransferase are induced during growth on acetoin, whereas they are absent or scarcely present in cells grown on a nonacetoinogenic substrate
-
transcriptions of the aco operon and acoR are repressed by glucose via CcpA, and CcpA specifically bound to sequences within the acoR promoter fragment
