Activating Compound

Activating Compound Comment Organism Structure
apolipoprotein A-I required Mus musculus
apolipoprotein A-I required Oryctolagus cuniculus
apolipoprotein A-I required, other apolipoprotein are less effective Homo sapiens

Protein Variants

Protein Variants Comment Organism
additional information enzyme deficiency phenotypes, overview. Generation of transgenic mice, monkeys, or rabbits overexpressing the human LCAT Homo sapiens
additional information overexpression of LCAT does not protect against diet-induced atherosclerosis, but in contrary does increase the atherosclerosis risk. LCAT knockout mice show markedly reduced plasma total cholesterol, cholesteryl esters, HDL-C, apolipoprotein A-I, and an increase in plasma triglycerides, the amount of alpha-HDl is decreased compared to wild-type mice Mus musculus

phosphatidylcholine + cholesterol in a first step, LCAT hydrolyzes the sn-2 acyl group of phosphatidylcholine and binds it at Ser181. In a second step, the enzyme transfers and esterifies the fatty acid to the 3beta-hydroxyl group on the A-ring of free cholesterol to form cholesteryl ester using apolipoprotein A-I as cofactor Mus musculus cholesteryl ester + lysophosphatidylcholine
