Cloned(Commentary)

Cloned (Comment) Organism
expression in Sf9 cell Homo sapiens
RDH10 is expressed the enzyme in insect Sf9 cells using the Baculovirus expression system. Purification of RDH10-His6 from Sf9 cells using nickel affinity chromatography produces an inactive enzyme. Therefore, microsomal preparations of RDH10 are used for its kinetic characterization Homo sapiens

Inhibitors

Inhibitors Comment Organism Structure
