== Function ==
[https://www.uniprot.org/uniprot/A2CIL3_LEIDO A2CIL3_LEIDO] Catalyzes the rate-limiting step of the oxidative pentose-phosphate pathway, which represents a route for the dissimilation of carbohydrates besides glycolysis.[RuleBase:RU362120]

== Publication Abstract from PubMed ==
Since unicellular parasites highly depend on NADPH as a source for reducing equivalents, the pentose phosphate pathway, especially the first and rate-limiting NADPH-producing enzyme glucose 6-phosphate dehydrogenase (G6PD), is considered an excellent antitrypanosomatid drug target. Here we present the crystal structure of Leishmania donovani G6PD (LdG6PD) elucidating the unique N-terminal domain of Kinetoplastida G6PDs. Our investigations on the function of the N-domain suggest its involvement in the formation of a tetramer that is completely different from related Trypanosoma G6PDs. Structural and functional investigations further provide interesting insights into the binding mode of LdG6PD, following an ordered mechanism, which is confirmed by a G6P-induced domain shift and rotation of the helical N-domain. Taken together, these insights into LdG6PD contribute to the understanding of G6PDs' molecular mechanisms and provide an excellent basis for further drug discovery approaches.
