STRINGSTRING
BNA2 protein (Saccharomyces cerevisiae) - STRING interaction network
"BNA2" - Tryptophan 2,3-dioxygenase or indoleamine 2,3-dioxygenase in Saccharomyces cerevisiae
Nodes:
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
some 3D structure is known or predicted
Edges:
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

BNA2Tryptophan 2,3-dioxygenase or indoleamine 2,3-dioxygenase; required for de novo biosynthesis of NAD from tryptophan via kynurenine; interacts genetically with telomere capping gene CDC13; regulated by Hst1p and Aftp; Catalyzes the first step in tryptophan catabolism in order to supply de novo nicotinamide adenine dinucleotide (NAD(+)) via the kynurenine pathway. Plays a role in the cellular response to telomere uncapping (453 aa)    
Predicted Functional Partners:
BNA5
Kynureninase, required for the de novo biosynthesis of NAD from tryptophan via kynurenine; expression regulated by Hst1p; Catalyzes the cleavage of L-kynurenine (L-Kyn) and L-3- hydroxykynurenine (L-3OHKyn) into anthranilic acid (AA) and 3- hydroxyanthranilic acid (3-OHAA), respectively (453 aa)
       
  0.971
BNA7
Formylkynurenine formamidase, involved in the de novo biosynthesis of NAD from tryptophan via kynurenine; Catalyzes the hydrolysis of N-formyl-L-kynurenine to L- kynurenine, the second step in the kynurenine pathway of tryptophan degradation. Kynurenine may be further oxidized to nicotinic acid, NAD(H) and NADP(H). Required for elimination of toxic metabolites (261 aa)
         
  0.956
ARO8
Aromatic aminotransferase I, expression is regulated by general control of amino acid biosynthesis; General aromatic amino acid transaminase involved in several otherwise unrelated metabolic pathways. Responsible for phenylalanine and tyrosine biosynthesis. Active with glutamate, phenylalanine, tyrosine and tryptophan as amino donors and with phenylpyruvate, hydroxyphenylpyruvate, 2-oxoglutarate and pyruvate as amino acceptors. Also active with methionine, alpha- aminoadipate and leucine as amino donors when phenylpyruvate is the amino acceptor and in the reverse reactions with the cor [...] (500 aa)
         
  0.934
DIT2
N-formyltyrosine oxidase, sporulation-specific microsomal enzyme involved in the production of N,N-bisformyl dityrosine required for spore wall maturation, homologous to cytochrome P-450s; Involved in spore wall maturation. Thought to catalyze the oxidation of tyrosine residues in the formation of LL- dityrosine a precursor of the spore wall (489 aa)
         
  0.902
TRP5
Tryptophan synthase, catalyzes the last step of tryptophan biosynthesis; regulated by the general control system of amino acid biosynthesis (707 aa)
         
  0.805
NPT1
Nicotinate phosphoribosyltransferase, acts in the salvage pathway of NAD+ biosynthesis; required for silencing at rDNA and telomeres and has a role in silencing at mating-type loci; localized to the nucleus; Essential for growth under anaerobic conditions (429 aa)
       
 
  0.795
BNA1
3-hydroxyanthranilic acid dioxygenase, required for the de novo biosynthesis of NAD from tryptophan via kynurenine; expression regulated by Hst1p; Catalyzes the oxidative ring opening of 3- hydroxyanthranilate to 2-amino-3-carboxymuconate semialdehyde, which spontaneously cyclizes to quinolinate (177 aa)
   
   
  0.731
BNA3
Kynurenine aminotransferase, catalyzes formation of kynurenic acid from kynurenine; potential Cdc28p substrate; Catalyzes the irreversible transamination of the L- tryptophan metabolite L-kynurenine to form kynurenic acid (KA) (444 aa)
           
  0.715
BNA4
Kynurenine 3-monooxygenase; required for the de novo biosynthesis of NAD from tryptophan via kynurenine; expression regulated by Hst1p; putative therapeutic target for Huntington disease; Catalyzes the hydroxylation of L-kynurenine (L-Kyn) to form 3-hydroxy-L-kynurenine (L-3OHKyn). Required for synthesis of quinolinic acid (460 aa)

CDC13
Single stranded DNA-binding protein found at TG1-3 telomere G-tails; regulates telomere replication through recruitment of specific sub-complexes, but the essential function is telomere capping; Single-stranded telomeric DNA-binding protein that regulates telomere replication. Has a role in both positive and negative regulation. Promotes [TG(1-3)] strand lengthening via interaction with EST1. Promotes [C(1-3)A] strand re-synthesis by DNA polymerase alpha via interaction with POL1. Negatively regulates telomere elongation of the G strand via binding with STN1 thereby inhibiting telomera [...] (924 aa)
