The structure of tryptophan 2,3-dioxygenase (TDO) from Ralstonia metallidurans was determined at 2.4 A. TDO catalyzes the… Expand Pyridine nucleotides are key redox carriers in the soluble phase of all living cells, and both NAD and NADP play crucial roles in… Expand Abstract: The metabolism of l‐tryptophan to the neuroactive kynurenine pathway metabolites, l‐kynurenine, kynurenate and… Expand Publisher Summary Quinolinic acid is found throughout nature in organisms ranging from bacteria to humans. Chemically this… Expand The two genes, nadA and nadB, responsible for quinolinate biosynthesis from aspartate and dihydroxyacetone phosphate in… Expand Liver cells pre-incubated with 1 mM-DL-6-chlorotryptophan are less sensitive to tryptophan-mediated inhibition of gluconeogenesis… Expand 1. The metabolism of L-tryptophan by liver cells prepared from fed normal, adrenalectomized and streptozotocin-diabetic rats was… Expand Evidence for the formation of an unstable intermediate in the synthesis of quinolinate from aspartate and dihydroxyacetone… Expand Abstract Two proteins (A and B) from Escherichia coli are required for the synthesis of the NAD precursor quinolinate from… Expand Dihydroxy [3-14C]acetone phosphate was prepared enzymatically from [1-14C]glucose and use as a substrate in a partially purified… Expand
