STRUCTURE OF P. FALCIPARUM PFPK5-PURVALANOL B LIGAND COMPLEX
Overview
Plasmodium falciparum cell cycle regulators are promising targets for, antimalarial drug design. We have determined the structure of PfPK5, the, first structure of a P. falciparum protein kinase and the first of a, cyclin-dependent kinase (CDK) not derived from humans. The fold and the, mechanism of inactivation of monomeric CDKs are highly conserved across, evolution. ATP-competitive CDK inhibitors have been developed as potential, leads for cancer therapeutics. These studies have identified regions of, the CDK active site that can be exploited to achieve significant gains in, inhibitor potency and selectivity. We have cocrystallized PfPK5 with three, inhibitors that target such regions. The sequence differences between, PfPK5 and human CDKs within these inhibitor binding sites suggest ...
