Four cross-bridge strands and high paramyosin content in the myosin filaments of honey bee flight muscles

Abstract

Measurements of the mass ratio of myosin to paramyosin of myofibrils of honey bee flight muscles on sodium dodecyl sulphate-polyacrylamide gels yielded a paramyosin content of 24% of the myosin filament mass. Based on the myosin to actin mass ratio of 2.3, and 3 actin filaments per myosin filament and per half sarcomere, it could be calculated that there… (More)
