Predicting function-related amino acids in proteins with unknown function or
unknown allosteric binding sites in drug-targeted proteins is a task of paramount
importance in molecular biomedicine. In this paper we introduce a simple, light
and computationally inexpensive structure-based method to identify catalytic
sites in enzymes. Our method, termed cutoff lensing, is a general procedure
consisting in letting the cutoff used to build an elastic network model increase
to large values. A validation of our method against a large database of annotated
enzymes shows that optimal values of the cutoff exist such that three different
structure-based indicators allow one to recover a maximum of the known catalytic
sites. Interestingly, we find that the larger the structures the greater the
predictive power afforded by our method. Possible ways to combine the three
indicators into a single figure of merit and into a specific sequential analysis
are suggested and discussed with reference to the classic case of HIV-protease.
Our method could be used as a complement to other sequence- and/or
structure-based methods to narrow the results of large-scale screenings.
