Abstract
Cardiac myosin light chains are phosphorylated in vivo and in vitro. The enzyme myosin light-chain kinase, has been purified and found to be very specific for cardiac myosin light chains. Experiments with skinned cardiac fibers suggest that phosphorylation of myosin light chain-2-decreases ATP consumption, presumably by lowering the cross-bridge cycle. These results are discussed in this chapter.
