General description
2-Isopropylmalic acid is an intermediate formed during leucine biosynthesis. Budding yeast Saccharomyces cerevisiae secrets 2-isopropylmalic acid and helps in reduction of aluminum toxicity by forming chelate with Al ions, thereby preventing them from entering the cells.
Application
2-Isopropylmalic acid was employed as an internal standard in diagnostic model for pancreatic cancer using GC/MS-based human serum metabolomics.

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

Reproductive failure associated with heat stress is a well-known phenomenon in poultry. High temperatures also induce various metabolic disturbances in many animals. Because the liver plays a central role in metabolism, the present study aimed to clarify the relationship between

Branched-chain amino acid (BCAA) catabolism is regulated by its rate-limiting enzyme, branched-chain α-keto acid dehydrogenase (BCKDH), which is negatively regulated by BCKDH kinase (BDK). Loss of BDK function in mice and humans leads to dysregulated BCAA catabolism accompanied by neurological
