The effect of myosin sulphydryl modification on the mechanics of fibre contraction

Glycerinated rabbit psoas fibres have been modified with paramagnetic probes ( IASL and MSL) which react selectively with the reactive sulphydryl on the myosin head. The extent of SH-1 modification was monitored by extracting myosin and measuring its ATPase activity in the presence of EDTA and of Ca...
