sterol esterase

sterol esterase
ster·ol es·ter·ase (sterґol esґtər-ās) [EC] an enzyme of the hydrolase class that catalyzes the cleavage of cholesterol and other sterol esters and triglycerides. Deficiency of the lysosomal enzyme causes the allelic autosomal recessive disorders Wolman disease and cholesteryl ester storage disease. Called also acid lipase and cholesterol esterase.
