Predicted to enable 3-hydroxybutyrate dehydrogenase activity; NAD binding activity; and oxidoreductase activity, acting on the CH-CH group of donors, NAD or NADP as acceptor. Predicted to be involved in several processes, including fatty acid beta-oxidation; heme metabolic process; and siderophore biosynthetic process. Predicted to be located in cytosol. Predicted to be active in cytoplasm. Orthologous to human BDH2 (3-hydroxybutyrate dehydrogenase 2). [provided by Alliance of Genome Resources, Apr 2022]
