Effects of cholesterol on the function and thermotropic properties of pure UDP-glucuronosyltransferase.


The effects of cholesterol on the activity and thermal properties of a pure, delipidated isoform of UDP-glucuronosyltransferase were examined after incorporation of enzyme into unilamellar bilayers of distearoylphosphatidylcholine (DSPC) or dioleoylphosphatidylcholine (DOPC). Cholesterol, in bilayers of DSPC, decreased enzyme activity and lowered the… (More)
