the effect of ph change on the reconstitution of aspartate aminotransferase ( ec 2.6.1.1 ) , i.e . the reactivation of the apoenzyme with coenzyme ( pyridoxal phosphate and pyridoxamine phosphate ) , was studied in the ph range 4.2-8.9 by using three buffer systems at concentrations ranging from 0.025 to 0.1m .
