enzymology Enzymes () are proteins that act as biological catalysts by accelerating chemical reactions. The molecules upon which enzymes may act are called substrates, and the enzyme converts the substrates into different molecules known as products. A ...

catalyzes Catalysis () is the process of increasing the rate of a chemical reaction by adding a substance known as a catalyst (). Catalysts are not consumed in the reaction and remain unchanged after it. If the reaction is rapid and the catalyst recyc ...

the chemical reaction :3-sn-phosphatidylcholine + dolichol

\rightleftharpoons

1-acyl-sn-glycero-3-phosphocholine + acyldolichol Thus, the two substrates of this enzyme are 3-sn-phosphatidylcholine and dolichol, whereas its two products are 1-acyl-sn-glycero-3-phosphocholine and acyldolichol. This enzyme belongs to the family of transferases, specifically those

acyltransferase Acyltransferase is a type of transferase enzyme that acts upon acyl groups. Examples include: * Glyceronephosphate O-acyltransferase * Lecithin-cholesterol acyltransferase *Long-chain-alcohol O-fatty-acyltransferase In enzymology, a long-chain- ...

s transferring groups other than aminoacyl groups. The systematic name of this enzyme class is 3-sn-phosphatidylcholine:dolichol O-acyltransferase.
