【評論內容】Phospholipase APhospholipase A1 – cleaves the sn-1 acyl chain (where sn refers to stereospecific numbering).Phospholipase A2 – cleaves the sn-2 acyl chain, releasing arachidonic acid.Phospholipase B – cleaves both sn-1 and sn-2 acyl chains; this enzyme is also known as a lysophospholipase.Phospholipase C – cleaves before the phosphate, releasing diacylglycerol and a phosphate-containing head group. PLCs play a central role in signal transduction, releasing the second messenger inositol triphosphate.Phospholipase D – cleaves after the phosphate, releasing phosphatidic acid and an alcohol.
