Population-based validation of dihydrofolate reductase gene mutations for the prediction of sulfadoxine-pyrimethamine resistance in Uganda.

, 2003
Mutations in the dihydrofolate reductase gene (dhfr) of Plasmodium falciparum have been proposed as molecular markers for the surveillance of sulfadoxine-pyrimethamine (SP)-resistant malaria, but such proposals have not been validated. At 7 Ugandan sites

Differential expression of nitrate reductase in response to potassium and sodium nitrate: realtime PCR analysis

, 2012
Cucurbita pepo L. plants were grown in plastic pots with 2 kg washed sand per pot at three levels of potassium and sodium nitrate supplies to investigate the effects of nitrate supply on nitrate reductase activity and nitrate reductase expression in the ...

A study into the cobalamin-dependent methionine synthase reactivation mechanism in corynebacterium glutamicum [PDF]

, 2009
PhDMethionine is one of the seven essential amino-acids for humans and is also used in feed supplements, predominantly for poultry and felines. Thus there is commercial interest in producing this nutrient. The final step in the biological synthesis of

Inhibition of pteridine reductase 1 (PTR1) expression in Leishmania promastigotes using a full-length antisense construct [PDF]

, 2009
Leishmania exhibit many unusual features, one of which is the pteridine metabolic pathway essential for the growth for these parasites. Leishmania have evolved a complex and versatile pteridine salvage network capable of scavenging a wide array of ...
