钙调素(CaM)被发现至今巳近二十年,CaM 广布于生物界,存在于真核细胞之中。1978年 Andersen 和 Corrmier 从植物和真菌中发现了 CaM 样活性后又作了提纯和研究工作,发现其化学、物理和生物特性与动物 CaM 相近,并且有 Ca~(2+)时动物、植物、真菌 CaM 均可激活植物 NAD 激酶。关于植物 CaM 参与生理功能调节的知识近年来也有报道。一、植物组织细胞中 CaM 的分布Muto 指出,小麦中 CaM 88%存在于细
Calmodulin (CaM) was found nearly two decades ago, CaM widely distributed in the biological world, exists in eukaryotic cells. In 1978, Andersen and Corrmier discovered CaM-like activity from plants and fungi, then purified and studied, and found that their chemical, physical and biological properties are similar to that of animal CaM, and that there are Ca 2+ -like animals, plants, Fungal CaM activates plant NAD kinase. Knowledge of plant CaM involved in the regulation of physiological functions has also been reported in recent years. First, the distribution of plant tissue CaM Muto pointed out that 88% of wheat CaM exists in the fine
