STRINGSTRING
STRING protein interaction network
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:
a 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 to each other.

yfbQAspartate aminotransferase is important for the metabolism of amino acids and Krebs-cycle related organic acids. In plants, it is involved in nitrogen metabolism and in aspects of carbon and energy metabolism. The enzyme catalyses the reaction: L-aspartate + 2-oxoglutarate = oxaloacetate + L-glutamate Similar to trembl|Q8XZR9 (72%),to trembl|Q9RAN0 (62%) and to sprot|YFBQ_ECOLI (57%). Pfam (PF00155): Aminotransferases class-I; Specificity unclear. (442 aa)    
Predicted Functional Partners:
gltB
Ferredoxin-dependent glutamate synthase,; Specificity unclear.

maeB1
Probable malate dehydrogenase (oxaloacetate-decarboxylating) (NADP+) (EC 1.1.1.40) (NADP-ME). Homology to dme of S. meliloti of 60% (sprot|MAO1_RHIME). Required for symbiotic nitrogen fixation. Plays a key role in the conversion of malate to acetyl-CoA for efficient tricarboxylic acid cycle function in nitrogen-fixating bacteria. Tigrfam: pta: phosphotransacetylase Pfam: Malic enzyme; Phosphate acetyl/butaryltransferase no signal peptide no TMHs; High confidence in function and specificity.

maeB2
Probable malate dehydrogenase (oxaloacetate-decarboxylating) (NADP+). Homology to dme of S. meliloti of 61% (sprot|MAO1_RHIME). Required for symbiotic nitrogen fixation. Plays a key role in the conversion of malate to acetyl-CoA for efficient tricarboxylic acid cycle function in nitrogen-fixating bacteria. InterPro: Phosphate acetyl/butaryl transferase (IPR002505); Malic enzyme (IPR001891) Pfam: Malic enzyme; Phosphate acetyl/butaryl transferase Tigrfam: pta: phosphotransacetylase no signal peptide no TMHs; High confidence in function and specificity.

argJ
Probable arginine biosynthesis bifunctional protein ArgJ; Catalyzes two activities which are involved in the cyclic version of arginine biosynthesis: the synthesis of N-acetylglutamate from glutamate and acetyl-CoA as the acetyl donor, and of ornithine by transacetylation between N(2)-acetylornithine and glutamate. Belongs to the ArgJ family.
    
 0.890
ilvE2
Branched-chain-amino-acid transaminase; Acts on leucine, isoleucine and valine. Belongs to the class-IV pyridoxal-phosphate-dependent aminotransferase family.
    
 0.887
leuA2
2-isopropylmalate synthase; Catalyzes the condensation of the acetyl group of acetyl-CoA with 3-methyl-2-oxobutanoate (2-oxoisovalerate) to form 3-carboxy-3- hydroxy-4-methylpentanoate (2-isopropylmalate); Belongs to the alpha-IPM synthase/homocitrate synthase family. LeuA type 2 subfamily.
     
 0.882
ilvD
Dihydroxy-acid dehydratase catalyzes the fourth step in the biosynthesis of isoleucine and valine, the dehydratation of 2,3-dihydroxy-isovaleic acid into alpha-ketoisovaleric acid. Similar to sprot|ILVD_PSEAE (74%) and sprot|ILVD_ECOL6 (72%). TIGRfam (TIGR00110): Dihydroxy-acid dehydratase Pfam (PF00920): Dihydroxy-acid and 6-phosphogluconate dehydratase; High confidence in function and specificity; Belongs to the IlvD/Edd family.
   
 
 0.878
argA
Amino-acid N-acetyltransferases acting mainly on glutamate in the first step of the 'acetylated' ornithine biosynthesis pathway. For this reason it is also called N-acetylglutamate synthase. The enzyme may also act on aspartate. Similar to sprot|ARGA_YERPE (44%) and to sprot|ARGA_ECOLI (43%). Pfam (PF00696): Aspartokinase superfamily Pfam (PF00583): GCN5-related N-acetyltransferase; Specificity unclear.

fumC
Fumarate hydratase; Involved in the TCA cycle. Catalyzes the stereospecific interconversion of fumarate to L-malate; Belongs to the class-II fumarase/aspartase family. Fumarase subfamily.
    
 0.875
sdhD
Succinate dehydrogenase, hydrophobic membrane anchor subunit. Homology to sdhD of C. burnetii of 41% (sprot|DHSD_COXBU). THIS IS THE HYDROPHOBIC COMPONENT OF THE SUCCINATE DEHYDROGENASE COMPLEX. IT IS SUGGESTED THAT IT IS REQUIRED TO ANCHOR THE CATALYTIC COMPONENTS TO THE CYTOPLASMIC MEMBRANE. no signal peptide 3 TMHS; Family membership.
