Isolation and expression analysis of the isopropylmalate synthase gene family of Arabidopsis thaliana
Isopropylmalate synthase (IPMS) is the first enzyme in the leucine biosynthetic pathway. It is the branch point in the biosynthesis of leucine and the other branched-chain amino acids. IPMS is also regulated by negative feedback inhibition by the end-product leucine. There are four highly homologous...

| Zusammenfassung: | Isopropylmalate synthase (IPMS) is the first enzyme in the leucine biosynthetic pathway. It is the branch point in the biosynthesis of leucine and the other branched-chain amino acids. IPMS is also regulated by negative feedback inhibition by the end-product leucine. There are four highly homologous loci within the Arabidopsis thaliana genome, which contain sequences that code for IPMS. Through library screening and RT-PCR the expression patterns of three of these loci namely IMS1, IMS2, and IMS3 have been isolated and then characterized. cDNAs of IMS2 and IMS3 lacking the 5' chloroplast leader sequence were able to complement a leucine auxotroph of E. coli |
