in order to study whether hormone-sensitive tyrosine aminotransferase exists in tissues other than liver , we have devised means to separate the liver-specific enzyme from other enzymes that transaminate tyrosine and to distinguish between the authentic enzyme and the principal `` '' pseudotyrosine aminotransferases , '' '' which are the isoenzymes of aspartate aminotransferase .
