Comparison of the electrophoretic patterns of creatine kinase in different birds throws some light on the type of evolutionary changes which have affected the multiple forms of this enzyme.

Molecular weights and distribution of kinases in echinoderms suggest that creatine kinase arose in the gamete of a common ancestral species and emerged in contemporary adult forms by parallel ...

Creatine kinase ― also known as creatine phosphokinase, or CPK ― is a muscle enzyme that exists as isoenzymes. The MB type is specific to myocardial cells, whereas MM and BB are specific to ...
