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

“…Moreover, both ilvC orthologues and paralogues were analysed, such that the relationship between gene duplication and functional diversification could be explored. The KARI paralogues present in S. coelicolor and Streptomyces lividans, despite their conserved high sequence identity (97%), were shown to be more promiscuous, suggesting a recent functional diversification. …”
