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.

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 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

Uptake of branched-chain amino acids by Saccharomyces cerevisiae from media containing a preferred nitrogen source is mediated by the permeases encoded by BAP2, BAP3, and VAP1/TAT1. The transcriptional activity of the BAP2 promoter is affected by a number of genes

LEU3 of Saccharomyces cerevisiae encodes an 886-amino-acid polypeptide that activates transcription of at least five genes by binding to an upstream decanucleotide sequence. This activation is dependent on the inducer alpha-isopropylmalate, the synthesis of which is repressed by leucine. We

Long-distance transportation is sometimes inevitable in the beef industry because of the geographic separation of major breeding and fattening areas. Long-distance transportation negatively impacts production and health of cattle, which may, at least partly, result from the disturbance of metabolism
