Molecular annotation of ketol-acid reductoisomerases fromStreptomycesreveals a novel amino acid biosynthesis interlock mediated by enzyme promiscuity por Verdel Aranda, Karina, López Cortina, Susana, Hodgson, David A., Barona Gómez, Francisco

“…Here, we obtain steady-state enzyme kinetic parameters for 10 IlvC homologues from the genera Streptomyces and Corynebacterium, upon eight selected chemically diverse substrates, including some not normally recognized by enzymes of this superfamily. This biochemical data suggested a Streptomyces biosynthetic interlock between proline and the branched-chain amino acids, mediated by enzyme substrate promiscuity, which was confirmed via mutagenesis and complementation analyses of the proC, ilvC1 and ilvC2 genes in Streptomyces coelicolor. …”
