[Bacterial membrane proteins. Properties of Micrococcus lysodeikticus NADH dehydrogenase].
NADH dehydrogenase was isolated from M. lysodeikticus membranes with FAD as a prosthetic group. It was found the enzyme molecular weight is about 140000 in 0,01 M phosphate buffer, pH 7,4 in 1% Triton X-100. The enzyme molecules are dimers consisting of two subunits with molecular weight of 70000. The content of alpha-helical regions is 30%, that of beta-forms is 13%. The protein globule is cross-linked with the disulfide bonds and has hydrophobic regions on its surface.
