D-beta-Hydroxybutyrate dehydrogenase (BDH), a lipid-requiring enzyme, has been purified to homogeneity from rat brain using a new improved method. The purified rat brain BDH has a subunit molecular mass of 31 kilodaltons on sodium dodecyl sulphate-polyacrylamide gel electrophoresis. The apoenzyme, i.e., the enzyme devoid of phospholipid, has no activity, but can be activated by phospholipid to a specific activity of 125 mumol/(min.mg). This is 625-fold greater than the activity in the mitochondrial fraction. The new purification procedure involves chromatography using a quaternary amine Sepharose resin followed by a sulphonate Sepharose resin, and eliminates the need for glass bead adsorption chromatography.

D001921	Brain	The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM.	Encephalon
