Abstract
Hepatic tyrosine aminotransferase (L-tyrosine: 2-oxoglutarate aminotransferase, EC 2.6.1.5) was partially purified from pyridoxine depleted and control rats and subsequently resolved by electrophoresis on polyacrylamide gels. Enzyme activity was detected histochemically in situ on the gel. Six enzymatically active forms were detected. Cofactor depletion effected further resolution of the enzyme into seven active forms as revealed by the bifurcation of the major active peak.Keywords
