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 the absence of the leucine biosynthetic precursor alpha-isopropylmalate (alpha-IPM), the yeast LEU3 protein (Leu3p) binds DNA and acts as a transcriptional repressor in an in vitro extract. Addition of alpha-IPM resulted in a dramatic increase in Leu3p-dependent transcription. The
