Brain-type creatine kinase B-CK (EC 2.7.3.2) was purified from several chicken tissues, e.g. cardiac muscle, brain, gizzard and retina. Two major monomeric chicken B-CK subunits, designated Bb (basic) and Ba (acidic), which differ in isoelectric point, were separated by chromatofocusing in the presence of 8 M urea on a MonoP column. The two subunits were shown by peptide mapping, amino acid analysis and partial sequencing, as well as by immunological criteria, to be distinct B-CK polypeptides… CONTINUE READING
