Abstract

The effect of calcitonin (CT) and parathyroid hormone (PTH) on carbonic anhydrase (carbonate hydrolyase, EC 4.2.1.1.) activity was tested in human erythrocyte hemolysates and with purified carbonic anhydrases I and II. The most important effect was on carbonic anhydrase II: CT showed a 2-fold increase and PTH showed a 50% decrease of carbonic anhydrase activity. This effect was observed at low hormonal concentrations and suggests the importance of CT in regulating carbonic anhydrase activity in the two important sites of CO2 exchange, erythrocyte and lung.

摘要

在人红细胞溶血产物以及纯化的碳酸酐酶I和II中,测试了降钙素(CT)和甲状旁腺激素(PTH)对碳酸酐酶(碳酸水解酶,EC 4.2.1.1.)活性的影响。最重要的影响是对碳酸酐酶II:CT使碳酸酐酶活性增加了2倍,而PTH使碳酸酐酶活性降低了50%。在低激素浓度下观察到了这种效应,这表明CT在调节二氧化碳交换的两个重要部位(红细胞和肺)的碳酸酐酶活性方面具有重要作用。
