A putative hydroxysteroid dehydrogenase involved in regulating plant growth and development. Plant Physiology 145 ,87-97. d'Andréa, S., Canonge, M., Beopoulos, A., Jolivet, P., Hartmann, M.A., Miquel, M., Lepiniec, L., Chardot, T. (2007). At5g50600 encodes a member of the short-chain dehydrogenase reductase superfamily with 11beta- and 17beta-hydroxysteroid dehydrogenase activities associated with Arabidopsis thaliana seed oil bodies. Biochimie 89 ,222-229. Lin, L.J., Tai, S.S.K., Peng, C.C., and Tzen, J.T.C. (2002). Steroleosin, a sterol-binding dehydrogenase in seed oil bodies. Plant Physiol. 128 , 1200-1211.	Identified by proteomics in purified seed oil bodies. Overexpression in E. coli: Encodes a hydroxysteroid dehydrogenase shown to act as a NADP+-dependent 11β-,17β-hydroxysteroid dehydrogenase/17β-ketosteroid reductase called HSD1. Two copies of HSD1 (At5g50600 and At5g50700) exist in the Arabidopsis genome as a result of an exact 33-kb duplication on chromosome 5.
