Reaction

Reaction Comment Organism Reaction ID
steryl ester + H2O = sterol + fatty acid a group of enzymes of broad specificity, acting on esters of sterols and long-chain fatty acids, that may also bring about the esterification of sterols. Activated by bile salts, reaction mechanism, catalytic triad consists of Ser194, His435, and Asp320 Sus scrofa
