However, there are several other lesser-known mechanisms of generating NADPH, all of which depend on the presence of mitochondria. The key enzymes in these processes are: NADP-linked malic enzyme , NADP-linked isocitrate dehydrogenase , NADP-linked glutamate dehydrogenase and nicotinamide nucleotide transhydrogenase. [1] The isocitrate dehydrogenase mechanism appears to be the major source of NADPH in fat and possibly also liver cells. [2] Also, in mitochondria, NADH kinase produces NADPH and ADP, using NADH and ATP as substrates.

The parasite cannot utilize preformed pyrimidines and must synthesize them from bicarbonate and glutamine ( see pyrimidine metabolism [HG] ). One step of pyrimidine synthesis involves an electron transport in which dihydroorotate dehydrogenase transfers electrons to an electron transport chain involving ubiquinone, cytochrome and molecular oxygen ( Gutteridge et al, 1979 ). This activity is probably located in the mitochondria and accounts for the microaerophillic requirements of the parasite. Pyrimidine synthesis also requires folates as co-factors ( see below ).

Hartnup disorder is an autosomal recessive impairment of neutral amino acid transport affecting the kidney tubules and small intestine. The disorder results from defects in the specific transport system responsible for neutral amino acid transport across the brush-border membrane of renal and intestinal epithelium. Deficiencies in the solute carrier family 6 (neurotransmitter transporter), member 19 gene (symbol SLC6A19) are associated with Hartnup disorder. The encoded protein is also referred to as the system B(0) neutral amino acid transporter 1 [B(0)AT1] protein. The characteristic diagnostic feature of Hartnup disorder is a dramatic neutral hyperaminoaciduria. Additionally, individuals excrete indolic compounds that originate from the bacterial degradation of unabsorbed tryptophan. The reduced intestinal absorption and increased renal loss of tryptophan lead to a reduced availability of tryptophan for nicotinamide adenine dinucleotide (NAD + and NADP + ) biosynthesis. As a consequence affected individuals frequently exhibit pellegra-like rashes
