NUCLEOSIDE DIPHOSPHATE KINASE ISOFORM B FROM BOVINE RETINA
OverviewOverview
The biochemical and structural properties of bovine retinal nucleoside, diphosphate kinase were investigated. The enzyme showed two polypeptides, of approximately 17.5 and 18.5 kDa on SDS-PAGE, while isoelectric focusing, revealed seven to eight proteins with a pI range of 7.4-8.2. Sedimentation, equilibrium yielded a molecular mass of 96 +/- 2 kDa for the enzyme., Carbohydrate analysis revealed that both polypeptides contained Gal, Man, GlcNAc, Fuc, and GalNac saccharides. Like other nucleoside diphosphate, kinases, the retinal enzyme showed substantial differences in the Km, values for various di- and triphosphate nucleotides. Immunogold labeling, of bovine retina revealed that the enzyme is localized on both the, membranes and in the cytoplasm. Screening of a retinal cDNA library, ... [(full description)]
