Abstract:
In silico analysis of the uncharacterized open reading frame YMR210w in Saccharomyces cerevisiae revealed that it possesses both an α/β hydrolase domain (ABHD) and a typical lipase (GXSXG) motif. The purified protein displayed monoacylglycerol (MAG) lipase activity and preferred palmitoyl-MAG. Overexpression of YMR210w in the known MAG lipase mutant yju3Δ clearly revealed that the protein had MAG lipase activity, hence we named the ORF MGL2. Overexpression of YMR210w decreased the cellular triacylglycerol levels. Analysis of the overexpressed strains showed reduction in the lipid droplets number and size. Phenotype studies revealed that the double deletion yju3Δmgl2Δ displayed a growth defect that was partially restored by MGL2 overexpression.
