Hi, people interested in high-throughput screening of enzyme inhibitors
might be interested in reading a paper currently in press in Analytical
Biochemistry:

The journal (don't know the volume or issue number yet) should appear in
libraries a few months from now. Here is the abstract:

ABSTRACT
Determination of tight-binding inhibition constants by
nonlinear least-squares regression requires sufficiently
good initial estimates of the best-fit values. Normally an
initial estimate of the inhibition constant must be provided
by the investigator. This paper describes an automatic
procedure for the estimation of tight-binding inhibition
constants directly from dose-response data. Because the
procedure does not require human intervention, it was
incorporated into an algorithm for high-throughput
screening of enzyme inhibitors. A suitable computer
program is available electronically
(http://www.biokin.com). Representative experimental
data are shown for the inhibition of human mast-cell
tryptase.
