Backbone and side-chain resonance assignments of Plasmodium falciparum SUMO

One of the most debilitating diseases Malaria, in its different forms, is caused by protozoan of Plasmodium species. Deadliest among these forms is the “cerebral malaria” which is afflicted upon by Plasmodium falciparum. Plasmodium adopts numerous strategies including various post-translational modifications (PTMs) to infect and survive in the human host. These PTMs have proven their critical requirement in the Plasmodium biology. Recently, sumoylation has been characterized as one of the important PTMs and many of its putative substrates have been identified in Plasmodium. Sumoylation is the covalent attachment of SUMO protein to the substrate protein, which is mediated by an enzyme cascade involving activating (E1), conjugating (E2), and ligating enzymes (E3). Here, we report resonance assignment for 1H, 13C and 15N of Plasmodium falciparum SUMO (Pf-SUMO) protein determined by various 2D and 3D heteronuclear NMR experiments along with predicted secondary structures.
