Abstract

The premature rabbit myocardium develops less force, which is partly explained by the low myofibrillar ATPase activity [1]. However, Lompre et al. [2] showed the increased proportion of isomyosin V1 (which has a high enzyme activity) in the newborn rabbit ventricle. The present study was designed to further delineate developmental changes in the contractile protein ATPase.
