Protein

7-dehydrocholesterol reductase

Gene

DWF5

Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

Production of cholesterol by reduction of C7-C8 double bond of 7-dehydrocholesterol (7-DHC). Lesions in the gene coding for the enzyme cause dwarfism.

Catalytic activityi

Cholesterol + NADP+ = cholesta-5,7-dien-3-beta-ol + NADPH.
