Purity > 90% as determined by SDS-PAGE. MW: 65.8kDa. Full Length of Mature Protein: 17-465aa. N-terminal 6xHis-SUMO-tagged. Mus musculus (Mouse). Plays an important role in fat metabolism. It preferentially splits the esters of long-chain fatty acids at positions 1 and 3, producing mainly 2-monoacylglycerol and free fatty acids, and shows considerably higher activity against insoluble emulsified substrates than against soluble ones (By similarity).
