PUBLIC DOMAIN PROGRAM DYNAFIT UPDATED
Program DYNAFIT for the analysis and simulation of enzyme
kinetic and receptor binding data was updated to version
2.17.1 (08/18/97). It has the capability to analyze multi-
response equilibrium binding data, where several dose res-
ponse curves are analyzed together, while each curve repre-
sents the equilibrium. concentration of a different species.
TEST PROBLEM: NUCLEASE/DNA BINDING MECHANISM
The new features of DYNAFIT are illustrated on complex
equilibria involved in nuclease catalysis. Two sets of
gell-shift data (courtesy Dr. Paul Mitsis, seQ Ltd., Prince-
ton NJ), representing the concentration of (1) the protein
trimer-DNA complex and (2) the hexamer-DNA complex, were
analyzed together. The standard error of equibrium constants
was lower than if both datasets are analyzed separately.
