| Abstract: | 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. |
