Substrate stereo‐specificity in tryptophan dioxygenase and indoleamine 2,3‐dioxygenase [PDF]

Proteins: Structure, Function, and Bioinformatics, 2010
AbstractThe first and rate‐limiting step of the kynurenine pathway, in which tryptophan (Trp) is converted to N‐formylkynurenine is catalyzed by two heme‐containing proteins, Indoleamine 2,3‐dioxygenase (IDO), and Tryptophan 2,3‐dioxygenase (TDO). In mammals, TDO is found exclusively in liver tissue, IDO is found ubiquitously in all tissues.

Sufficiency of hypoxia-inducible 2-oxoglutarate dioxygenases to block chemical oxidative stress-induced differentiation of human embryonic stem cells

Stem Cell Research, 2019
Hypoxia benefits undifferentiated pluripotent stem cell renewal, and 2-oxoglutarate (2OG) dioxygenases have been implicated in pluripotent stem cell induction and renewal.

Structure of an aromatic-ring-hydroxylating dioxygenase – naphthalene 1,2-dioxygenase [PDF]

Structure, 1998
Pseudomonas sp. NCIB 9816-4 utilizes a multicomponent enzyme system to oxidize naphthalene to (+)-cis-(1R,2S)-dihydroxy-1,2-dihydronaphthalene. The enzyme component catalyzing this reaction, naphthalene 1,2-dioxygenase (NDO), belongs to a family of aromatic-ring-hydroxylating dioxygenases that oxidize aromatic hydrocarbons and related compounds to cis ...

Does abscisic acid affect strigolactone biosynthesis? [PDF]

, 2010
Strigolactones are considered a novel class of plant hormones that, in addition to their endogenous signalling function, are exuded into the rhizosphere acting as a signal to stimulate hyphal branching of arbuscular mycorrhizal (AM) fungi and germination
