ENDOTHIAPEPSIN PD135,040 COMPLEX
Overview
The crystal structure of endothiapepsin complexed with the gem-diol, inhibitor PD-135,040 has been anisotropically refined to a resolution of, 1.37 A. The structure of this inhibitor complex is in agreement with, previous structures of endothiapepsin gem-diol inhibitor complexes that, have been used to develop proposed catalytic mechanisms. However, the, increase in resolution over previous structures confirms the presence of a, number of short hydrogen bonds within the active site that are likely to, play an important role in the catalytic mechanism. The presence of, low-barrier hydrogen bonds was indicated in a previous one-dimensional H, NMR spectrum.
