Query author contributions in Reactome

Reactome depends on collaboration between our curation team and outside experts to assemble and peer-review its pathway modules. The integration of ORCID within Reactome enables us to meet a key challenge with authoring, curating and reviewing biological information by incentivizing and crediting the external experts that contribute their expertise and time to the Reactome curation process. More information is available at ORCID and Reactome.

If you have an ORCID ID that is not listed on this page, please forward this information to us and we will update your Reactome pathway records.

commentFUNCTION Transaminase with broad substrate specificity. Has transaminase activity towards aminoadipate, kynurenine, methionine and glutamate. Shows activity also towards tryptophan, aspartate and hydroxykynurenine. Accepts a variety of oxo-acids as amino-group acceptors, with a preference for 2-oxoglutarate, 2-oxocaproic acid, phenylpyruvate and alpha-oxo-gamma-methiol butyric acid. Can also use glyoxylate as amino-group acceptor (in vitro).CATALYTIC ACTIVITY glycine + 2-oxoglutarate = glyoxylate + L-glutamateCATALYTIC ACTIVITY L-kynurenine + 2-oxoglutarate = kynurenate + L-glutamate + H2OCATALYTIC ACTIVITY L-kynurenine + glyoxylate = kynurenate + glycine + H2OCATALYTIC ACTIVITY 3-hydroxy-L-kynurenine + glyoxylate = xanthurenate + glycine + H2OCATALYTIC ACTIVITY 2-oxohexanoate + L-kynurenine = L-2-aminohexanoate + kynurenate + H2OCATALYTIC ACTIVITY 3-phenylpyruvate + L-kynurenine = kynurenate + L-phenylalanine + H2OCATALYTIC ACTIVITY 4-methylsulfanyl-2-oxobutanoate + L-kynurenine = kynurenate + L-methionine + H2OCATALYTIC ACTIVITY 2-oxo-3-sulfanylpropanoate + L-kynurenine = kynurenate + L-cysteine + H2OCATALYTIC ACTIVITY indole-3-pyruvate + L-kynurenine = kynurenate + L-tryptophan + H2OCATALYTIC ACTIVITY 2-oxopentanoate + L-kynurenine = L-2-aminopentanoate + kynurenate + H2OCATALYTIC ACTIVITY 4-methyl-2-oxopentanoate + L-kynurenine = kynurenate + L-leucine + H2OCATALYTIC ACTIVITY L-2-aminoadipate + 2-oxoglutarate = 2-oxoadipate + L-glutamateCATALYTIC ACTIVITY glyoxylate + L-methionine = 4-methylsulfanyl-2-oxobutanoate + glycineCATALYTIC ACTIVITY L-2-aminoadipate + glyoxylate = 2-oxoadipate + glycineCATALYTIC ACTIVITY L-tyrosine + glyoxylate = 3-(4-hydroxyphenyl)pyruvate + glycineCATALYTIC ACTIVITY glyoxylate + L-phenylalanine = 3-phenylpyruvate + glycineCATALYTIC ACTIVITY L-tryptophan + glyoxylate = indole-3-pyruvate + glycineCATALYTIC ACTIVITY L-leucine + glyoxylate = 4-methyl-2-oxopentanoate + glycineCATALYTIC ACTIVITY 2-oxobutanoate + L-kynurenine = (2S)-2-aminobutanoate + kynurenate + H2OCATALYTIC ACTIVITY 2-oxoadipate + L-kynurenine = L-2-aminoadipate + kynurenate + H2OCOFACTOR Kynurenine transaminase activity is competitively inhibited by aminoadipate, asparagine, glutamate, histidine, cysteine, lysine, 3-hydroxy-kynurenine and phenylalanine.BIOPHYSICOCHEMICAL PROPERTIES Optimum pH is 7-9.PATHWAY Amino-acid degradation; L-lysine degradation via saccharopine pathway; glutaryl-CoA from L-lysine: step 4/6.SUBUNIT Homodimer.SUBCELLULAR LOCATION Higher expression in the liver. Also found in heart, brain, kidney, pancreas, prostate, testis and ovary.MISCELLANEOUS May be due to a competing donor splice site.SIMILARITY Belongs to the class-I pyridoxal-phosphate-dependent aminotransferase family.
