on the other hand , starting from a reductase-free preparation , we have obtained by high-performance ion-exchange chromatography and high-performance size-exclusion chromatography , only partial purification of the aromatase cytochrome p-450 , which showed the following values : aromatase activity , 3.995 nmol/min/mg protein ( 60-fold purification ) ;
C0030016
reductase
C0003805
