Blumenthal, Donald K. | Effects of deletions in the central helix of calmodulin on enzyme activation and peptide binding. | Using site-directed mutagenesis we have expressed in Escherichia coli three engineered calmodulins (CaM) containing deletions in the solvent-exposed region of the central helix. These are CaM delta 84, Glu-84 removed; CaM delta 83-84, Glu-83 and Glu-84 removed; and CaM delta 81-84, Ser-81 through Gl... | Drug Effects; Genetics; Metabolism | 1989-05-15 |

Hendee, Shonn P.; Faour, Fouad A.; Christensen, Douglas A.; Patrick, Baharah; Durney, Carl H.; Blumenthal, Donald K. | Effects of weak extremely low frequency magnetic fields on calcium/calmodulin interactions. | Mechanisms by which weak electromagnetic fields may affect biological systems are of current interest because of their potential health effects. Lednev has proposed an ion parametric resonance hypothesis (Lednev, 1991, Bioelectromagnetics, 12:71-75), which predicts that when the ac, frequency of a c... | Electromagnetic Fields; Calcium-binding Proteins; Lednev's Theory | 1996-06 |
