Abstract
We ascertained by the stopped flow method the overall association rate constant, k(+1), of filamin and alpha-actinin to fluorescently labell ed filamentous actin of similar to 1.3x10(6)M(-1).s(-1) and similar to 1.0x10(6)M(-1).s(-1) as well as the overall dissociation rate constan t, k(-1) of similar to 0.6s(-1) and similar to 0.4s(-1), respeetively. The overall equilibrium constant, K, for filamin and alpha-actinin to actin deduced from the relation K=k(+1)/k(-1) agree well with publish ed data.
