The enzyme alpha-isopropylmalate synthase from Mycobacterium tuberculosis (MtIPMS) has been identified as a possible target for the design of new antitubercular therapeutics. Recently, it was shown that MtIPMS is subject to slow-onset, feedback inhibition by l-leucine, the first instance of

The budding yeast Saccharomyces cerevisiae secretes 2-isopropylmalic acid (2-iPMA), an intermediate in leucine biosynthesis. Because 2-iPMA binds Al(III) in the culture medium, it is thought to reduce toxicity by Al(III). The effects of 2-iPMA and malic acid (MA) on Al

In Saccharomyces cerevisiae, alpha-isopropylmalate (alpha-IPM), which is produced in mitochondria, must be exported to the cytosol where it is required for leucine biosynthesis. Recombinant and reconstituted mitochondrial oxalacetate carrier (Oac1p) efficiently transported alpha-IPM in addition to its known substrates oxalacetate

The Leu3 protein of Saccharomyces cerevisiae has been shown to be a transcriptional regulator of genes encoding enzymes of the branched-chain amino acid biosynthetic pathways. Leu3 binds to upstream activating sequences (UASLEU) found in the promoters of LEU1, LEU2, LEU4
D Armaleo et al.
Molecular & general genetics : MGG, 200(2), 346-349 (1985-01-01)
The leu-3/alpha-IPM (alpha-isopropylmalate) regulatory system, previously shown to control several genes of leucine, isoleucine, valine, and histidine biosynthesis, appears likely to be involved also in the regulation of overall RNA and protein synthesis in Neurospora. Upon addition of alpha-IPM the
