Protein

Monoglyceride lipase

Gene

YJU3

Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Converts monoacylglycerides (MAG) to free fatty acids and glycerol. Required for efficient degradation of MAG, short-lived intermediates of glycerolipid metabolism which may also function as lipid signaling molecules. Controls inactivation of the signaling lipid N-palmitoylethanolamine (PEA).2 Publications

Miscellaneous

Present with 2140 molecules/cell in log phase SD medium.1 Publication

Catalytic activityi

Hydrolyzes glycerol monoesters of long-chain fatty acids.1 Publication

Kineticsi

  1. KM=260 µM for rac-13-oleoylglycerol1 Publication
  1. Vmax=10.3 mmol/h/mg enzyme1 Publication

pH dependencei

Active from pH 4.5 to 8.1 Publication

Pathwayi: triacylglycerol degradation

This protein is involved in the pathway triacylglycerol degradation, which is part of Glycerolipid metabolism.1 Publication
View all proteins of this organism that are known to be involved in the pathway triacylglycerol degradation and in Glycerolipid metabolism.
