in this study we used limited proteolysis to study the structure of bovine brain kinesin , a heterotetramer composed of two heavy ( 120-kda ) and two light ( 62-kda ) chains . alpha-chymotrypsin , trypsin , and subtilisin all produced a protease-resistant 45-kda fragment from the kinesin heavy chain .
