In this study we have examined the cholesterol oxidase (Streptomyces cinnamomeus) catalyzed conversion of either 5-cholesten-3 beta-ol or 5-cholesten-3-one into 4-cholesten-3-one in pure sterol or mixed phospholipid-containing monolayers at the air/buffer interface. The mean molecular area requirement of 5-cholesten-3-one in

Cholesterol oxidase catalyzes the oxidation and isomerization of cholesterol to cholest-4-en-3-one via cholest-5-en-3-one. It has been proposed that His447 acts as the general base catalyst for oxidation, and that the resulting imidazolium ion formed acts as an electrophile for isomerization.
Refolding of a novel cholesterol oxidase from Pimelobacter simplex reveals dehydrogenation activity.

Cholesterol oxidases, which catalyze the degradation of cholesterol to cholest-4-en-3-one, are widely used in the pharmaceutical and food processing industries. The cholesterol oxidase from Pimelobacter simplex (PsChO3) was transformed into E. coli BL21(DE3), but it was expressed mainly as inclusion bodies

Cholesterol oxidase stereospecifically isomerizes cholest-5-en-3-one to cholest-4-en-3-one. When the base catalyst for isomerization, Glu361, is mutated to Asp, the rate of deprotonation of cholest-5-en-3-one is not affected, but protonation of the dienolic intermediate becomes rate-limiting. This may be a consequence

Sterols have been reported to modulate conformation and hence the function of several membrane proteins. One such group is the Chloride Intracellular Ion Channel (CLIC) family of proteins. The CLIC protein family consists of six evolutionarily conserved protein members in
