摘要

研究了在5′-磷酸吡哆醛存在下，温度与天冬氨酸转氨酶行为的关系。体外添加吡哆醛5′-磷酸后，天冬氨酸转氨酶活性增加，热行为发生改变。因此，在选择测定酶活性的温度时，还必须考虑辅酶的浓度。

[The influence of pyridoxal 5'-phosphate on the temperature relationships of aspartate aminotransferase isoenzymes].

The relationship between temperature and the behaviour of aspartate aminotransferase was investigated in the presence of pyridoxal 5'-phosphate. The addition in vitro of pyridoxal 5'-phosphate caused an increase in the activity and altered the thermal behaviour of aspartate aminotransferase. In choosing the temperature for the determination of enzymic activity, the concentration of the coenzyme must therefore also be considered.
