The first evidence for a calmodulin-like protein in an archaeon, Halobacterium salinarium, is reported here. The calmodulin-like protein, with a molecular mass of 24 kDa and an estimated pI of 4.8, stimulated cyclic nucleotide phosphodiesterase in a calcium-dependent manner. This stimulation could be suppressed by calmodulin inhibitors. The Ca(2+)-binding ability was verified by 45Ca autoradiography.
本文报道了古细菌盐生盐杆菌中存在类钙调蛋白的首个证据。该类钙调蛋白分子量为24 kDa,估计pI为4.8,以钙依赖方式刺激环核苷酸磷酸二酯酶。这种刺激可被钙调蛋白抑制剂抑制。通过45Ca放射自显影验证了其Ca(2+)结合能力。
