- Platelet-activating factor acetyltransferase
In
enzymology , a platelet-activating factor acetyltransferase (EC number|2.3.1.149) is anenzyme that catalyzes thechemical reaction :1-alkyl-2-acetyl-sn-glycero-3-phosphocholine + 1-organyl-2-lyso-sn-glycero-3-phospholipid ightleftharpoons 1-organyl-2-lyso-sn-glycero-3-phosphocholine + 1-alkyl-2-acetyl-sn-glycero-3-phospholipid
Thus, the two substrates of this enzyme are
1-alkyl-2-acetyl-sn-glycero-3-phosphocholine and1-organyl-2-lyso-sn-glycero-3-phospholipid , whereas its two products are1-organyl-2-lyso-sn-glycero-3-phosphocholine and1-alkyl-2-acetyl-sn-glycero-3-phospholipid .This enzyme belongs to the family of
transferase s, specifically thoseacyltransferase s transferring groups other than aminoacyl groups. The systematic name of this enzyme class is 1-alkyl-2-acyl-sn-glycero-3-phosphocholine:1-organyl-2-lyso-sn-glyce ro-3-phospholipid acetyltransferase. This enzyme is also called PAF acetyltransferase.References
