The crystal structures of two hydroxymethyl ketone inhibitors complexed to the cysteine protease cruzain have been determined at 1.1 and 1.2 A resolution, respectively. These high resolution crystal structures provide the first structures of non-covalent inhibitors bound to cruzain. A series of compounds were prepared and tested based upon the structures providing further insight into the key binding interactions.

High Resolution Crystal Structure Analysis Of Cruzain non-covalently Bound To A Hydroxymethyl Ketone Inhibitor (I)High Resolution Crystal Structure Analysis Of Cruzain non-covalently Bound To A Hydroxymethyl Ketone Inhibitor (I)

Structural highlights

1me4 is a 1 chain structure with sequence from Trypanosoma cruzi. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
Method:X-ray diffraction, Resolution 1.2Å
Ligands:
Resources:FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT

Function

CYSP_TRYCR Hydrolyzes chromogenic peptides at the carboxyl Arg or Lys; requires at least one more amino acid, preferably Arg, Phe, Val or Leu, between the terminal Arg or Lys and the amino-blocking group. The cysteine protease may play an important role in the development and differentiation of the parasites at several stages of their life cycle.

Evolutionary Conservation

Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf.
