Structure of ribose 5-phosphate isomerase from Plasmodium falciparum

The structure of ribose 5-phosphate isomerase from Plasmodium falciparum, PFE0730c, has been determined by molecular replacement at 2.09 A resolution. The enzyme, which catalyzes the isomerization reaction that interconverts ribose 5-phosphate and ribulose 5-phosphate, is a member of the pentose phosphate pathway. The P. falciparum enzyme belongs to the ribose 5-­phosphate isomerase A family, Pfam family PF06562 (DUF1124), and is structurally similar to other members of the family.
