Three crystal structures of the molybdenum-cofactor biosynthesis protein MogA from two highly thermophilic organisms have been determined at high resolution. Comparative analyses revealed the residues involved in oligomerization. In addition, molecular-dynamics and docking studies suggested the binding affinities of several small molecules towards MogA and homologous proteins.

The structure of L. donovani pteridine reductase has been targeted to assist in a program of structure-based inhibitor research. Crystals that diffracted to 2.5 Å resolution were obtained and the structure has been solved. Unfortunately, the active site is disordered and this crystal form is unsuitable for use in characterizing enzyme–ligand interactions.
