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

“…Ketolacid reductoisomerase (KARI), encoded by the ilvC gene in branched-chain amino acids biosynthesis, is a promiscuous reductase enzyme within this superfamily. 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. …”
