Light Chains from Fast and Slow Muscle Myosins

Abstract

Myosin from fast skeletal muscles consists of two large subunits (each about 200,000 daltons) and approximately four smaller subunits (in the range of 20,000 daltons). The light chains are heterogeneous in both size and charge, irrespective of the muscle type of origin. Moreover, the myosins from fast muscles of several species show a characteristic light chain pattern which is distinct from that of slower muscles.
