S. Parthasarathy, H. Balaram, P. Balaram and M. R. N. Murthy

Synopsis: Structures of triosephosphate isomerase (TIM) from the malarial parasite P. falciparum (Pf) complexed to the substrate analogues 3-phosphoglycerate and glycerol-3-phosphate have been determined at 2.4 Å resolution. The catalytic loop of TIM adopts a novel `loop-open' conformation in these complexes. These structures provide insight into the design of inhibitors specific for the malarial enzyme.

A nanodrop dispensing robot (50-200 nl) proved to be useful for obtaining diffracting crystals while using small amounts of protein. In 10 months, 25 proteins were subjectred to crystallization, 13 yielded crystals among which ten led to usuable data sets and five to structures.
