Inability of the smallest light chain to bind to fetal fast muscle myosin.
1. The smallest light chain of myosin, g3, was not transferred from adult HMM to fetal myosin in alkali (pH 10.5) under conditions when the light chains dissociated from myosin. 2. The g3 isolated from adult myosin did not bind to fetal myosin at either pH 7.8 or 10.5.
