Nucleotide binding by actomyosin as a determinant of relaxation kinetics of rabbit phasic and tonic smooth muscle.

1. The apparent second-order rate constants (k+T) of ATP-induced cross-bridge detachment from rigor in the absence of Ca2+ were determined with laser flash photolysis of caged ATP (cATP) in alpha-toxin-permeabilized tonic, rabbit femoral artery and phasic, rabbit bladder smooth muscles. The potentia...
