Abstract

Crude extracts from submandibular glands of the rat, rabbit, guinea pig and macaque monkey contained high activities of branched-chain amino acid aminotransferase comparable to those from the heart and kidney. In each species, the isoelectric point and relative elution volume on Sephacryl of the aminotransferase from the submandibular gland had the same values as the heart enzyme. The enzyme of rat submandibular gland was partially purified; the properties of the purified enzyme suggest that it is the same type as that from the heart.

摘要

大鼠、兔子、豚鼠和猕猴下颌下腺的粗提物中含有与心脏和肾脏相当的高活性支链氨基酸转氨酶。在每个物种中,下颌下腺转氨酶在Sephacryl上的等电点和相对洗脱体积与心脏酶的值相同。大鼠下颌下腺的酶被部分纯化;纯化酶的特性表明它与心脏的酶属于同一类型。
