Results We recognized eqolisin homologs by means of iterative HMMER analysis of the NR database. The recognized sequences were scrutinized for which new hallmarks were recognized by molecular dynamics simulations of mutants in highly conserved positions, using the structure of an eqolisin that was crystallized in the presence of a transition state inhibitor. Four conserved glycines were shown to be important for features. A substitution of W67F is definitely shown to be accompanied from the L105W substitution. Molecular dynamics demonstrates the W67 4E2RCat binds to the substrate via a – stacking and a salt bridge, the second option being stronger inside a virtual W67F/L105W double mutant of the resolved structure.
