“…Recently, patatin was found to be identical to a cytosolic Abbreviations: DTNB, 5,5'-dithio-bis(2-nitrobenzoic acid); cPLA 2 , cytosolic calcium-dependent phospholipase A 2 ; PatB2, Patatin subclass B2. Definition: phospholipids are named according to the IUBMB recommmendations as follows: PCho, phosphocholine; diC 6 PCho, 1,2-dihexanoyl-sn-glycero-3-phosphocholine; diC 7 PCho, 1,2-diheptanoyl-sn-glycero-3-phosphocholine; diC 8 PCho, 1,2-dioctanoyl-sn-glycero-3-phosphocholine; diC 9 PCho, 1,2-dinonanoyl-sn-glycero-3-phosphocholine; diC 10 PCho, 1,2-didecanoyl-sn-glycero-3-phosphocholine; diC 12 PCho, 1,2-didodecanoyl-sn-glycero-3-phosphocholine; diC 16 PCho, 1,2-dihexadecanoyl-sn-glycero-3-phosphocholine; C 18 lysoPCho, 1-octadecanoyl-2-lyso-sn-glycero-3-phosphocholine; C 8 thioglycolPCho, 2-octanoylthio-ethane-1-phosphocholine; C 12 thioglycolPCho, 2-dodecanoylthio-ethane-1-phosphocholine; C 16 thioglycolPCho, 2-hexadecanoylthio-ethane-1-phosphocholine; diC 8 dithioPCho, rac-1,2-dioctanoyldithiopropyl-3-phosphocholine phospholipase A 2 (cPLA 2 ) from potato [15], shedding new light on its possible physiological function. As a storage protein, patatin is mainly localized in the vacuoles where it is inactive.…”
