A circannual study of tyrosine aminotransferase and other metabolic enzymes in frog liver is reported. The subcellular distribution of all enzymatic activities under investigation was also studied. Results show significant oscillations of all enzymatic activities throughout the year; in particular tyrosine aminotransferase has a marked summer maximum. The subcellular distribution of tyrosine aminotransferase shows significant variations: the soluble activity of the enzyme presents a bimodal circannual distribution, which has its counterpart in an increased activity of heavier fractions.
本文报道了对青蛙肝脏中酪氨酸转氨酶及其他代谢酶进行的一项年度研究。同时还研究了所有被调查酶活性的亚细胞分布情况。结果显示，所有酶活性在全年都有显著波动；尤其是酪氨酸转氨酶在夏季有明显的最高值。酪氨酸转氨酶的亚细胞分布呈现出显著变化：该酶的可溶性活性呈现双峰年度分布，而在较重的组分中活性增加与之相对应。
