The rate constant and equilibrium constant of association of an actin monomer with 1:1 gelsolin-actin complex isolated from chicken were measured by using fluorescently labeled actin. According to fluorescence stopped-flow experiments, the rate constant of formation of the 1:2 gelsolin-actin complex from 1:1 gelsolin-actin complex and actin was found to be about 2 x 10(7) M-1 s-1 under conditions where gelsolin binds Ca2+. The rate of dissociation of one actin molecule from the 1:2 gelsolin… CONTINUE READING
