アプリケーション
The enzyme sequence is derived from Nocardia sp., and this cholesterol dehydrogenase is expressed in Streptomyces lividans. Cholesterol Dehydrogenase from Nocardia sp. has been used in the preparation of amperometric cholesterol biosensor for cholesterol detection in biological samples and in a study to investigate the atomic structure of the autosomal recessive hypercholesterolemia phosphotyrosine-binding domain with the LDL-receptor tail. Cholesterol dehydrogenase from Nocardia sp. Has also been used in a study to assess organization, dynamics, and segregation of Ras nanoclusters in membrane domains.

生物化学的／生理学的作用
Cholesterol dehydrogenase (CDH) is a nicotinamide adenine dinucleotide phosphate (NAD(P)) dependent microbial dehydrogenase that oxidizes the 3-β-hydroxyl group of cholesterol to yield cholest-4-ene-3-one. Cholesterol detection by using CDH allows direct and easier quantification compared to cholesterol oxidase based assay.
Cholesterol dehydrogenase is a NAD(P) dependent microbial dehydrogenase that oxidizes the 3-β-hydroxyl group of cholesterol to yield cholest-4-ene-3-one. Molecular mass of the protein is found to be 37 kDa based on SDS-PAGE. Its pH is 4.5.

Mechanosensitive (MS) channels of small (MscS) and large (MscL) conductance are the major players in the protection of bacterial cells against hypoosmotic shock. Although a great deal is known about structure and function of these channels, much less is known

Recent experiments have shown that membrane-bound Ras proteins form transient, nanoscale signaling platforms that play a crucial role in high-fidelity signal transmission. However, a detailed characterization of these dynamic proteolipid substructures by high-resolution experimental techniques remains elusive. Here we use
