Enzymes

Enzyme Details

1. Kynurenine--oxoglutarate transaminase 1

General function:: Involved in 1-aminocyclopropane-1-carboxylate synthase activity
Specific function:: Catalyzes the irreversible transamination of the L-tryptophan metabolite L-kynurenine to form kynurenic acid (KA). Metabolizes the cysteine conjugates of certain halogenated alkenes and alkanes to form reactive metabolites. Catalyzes the beta-elimination of S-conjugates and Se-conjugates of L-(seleno)cysteine, resulting in the cleavage of the C-S or C-Se bond.
Gene Name:: CCBL1
Uniprot ID:: Q16773
Molecular weight:: 47874.765

Reactions

Se-Methylselenocysteine + 2-Oxo-4-methylthiobutanoic acid → Methylselenopyruvate + L-Methionine	details

Enzyme Details

2. Kynurenine--oxoglutarate transaminase 3

General function:: Involved in transferase activity, transferring nitrogenous groups
Specific function:: Catalyzes the irreversible transamination of the L-tryptophan metabolite L-kynurenine to form kynurenic acid (KA). May catalyze the beta-elimination of S-conjugates and Se-conjugates of L-(seleno)cysteine, resulting in the cleavage of the C-S or C-Se bond (By similarity). Has transaminase activity towards L-kynurenine, tryptophan, phenylalanine, serine, cysteine, methionine, histidine, glutamine and asparagine with glyoxylate as an amino group acceptor (in vitro). Has lower activity with 2-oxoglutarate as amino group acceptor (in vitro) (By similarity).
