Triacylglycerol lipase 3, 4, and 5 and Sugar-Dependent 1 lipase
Triacylglycerol lipases are involved in triacylglycerol mobilization and degradation; they are found in lipid particles. TGL4 is 30% homologus to TGL3, whereas TGL5 is 26% homologus to TGL3. Sugar-Dependent 1 (SDP1) lipase has a patatin-like acyl-hydrolase domain that initiates the breakdown of storage oil in germinating Arabidopsis seeds. This family includes subfamilies of proteins: TGL3, TGL4, TGL5, and SDP1.
