Phosphorylation of the 20,000-dalton light chain of myosin is closely correlated with cross-
bridge cycling in arterial smooth muscle. Evidence is presented that dephosphorylation can
produce an attached, noncycling cross-bridge (latch-bridge) which is responsible for the
high economy of force maintenance in this tissue.
