Abstract
The mitochondrial hexokinase from rat brain, selectively released from mitochondria by the action of glucose 6-phosphate, can be purified to greater than 90% homogeneity by a single affinity chromatography step on Affi-Gel Blue; the Cibacron Blue F3GA ligand bound to this matrix serves as an analog of ATP, the normal substrate for the enzyme, and selective elution is accomplished using glucose 6-phosphate which is a competitive ligand vs. ATP. With this and other modifications to the previously described procedure (Ref. 8), highly purified enzyme is readily obtained in good yield and with retention of the ability to rebind to mitochondria.This publication has 22 references indexed in Scilit:
