ABSTRACT We have developed a method to
both predict the geometry and the relative stability
of point mutants that may be used for arbitrary
mutations. The geometry optimization procedure
was first tested on a new benchmark of 2141 ordered
pairs of X-ray crystal structures of proteins that
differ by a single point mutation, the largest data set
to date. An empirical energy function, which in-
cludes terms representing the energy contributions
of the folded and denatured proteins and uses the
predicted mutant side chain conformation, was fit
to a training set consisting of half of a diverse set of
1816 experimental stability values for single point
