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:
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 to each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

panB3-methyl-2-oxobutanoate hydroxymethyltransferase; Catalyzes the reversible reaction in which hydroxymethyl group from 5,10-methylenetetrahydrofolate is transferred onto alpha- ketoisovalerate to form ketopantoate (264 aa)    
Predicted Functional Partners:
panC
Pantoate--beta-alanine ligase; Catalyzes the condensation of pantoate with beta-alanine in an ATP-dependent reaction via a pantoyl-adenylate intermediate
 
 0.999
panE
2-dehydropantoate reductase, NADPH-specific; Catalyzes the NADPH-dependent reduction of ketopantoate into pantoic acid
  
 0.997
panD
Aspartate 1-decarboxylase proenzyme; Catalyzes the pyruvoyl-dependent decarboxylation of aspartate to produce beta-alanine
 
  
 0.994
ilvC
Ketol-acid reductoisomerase, nad(p)-binding; Involved in the biosynthesis of branched-chain amino acids (BCAA). Catalyzes an alkyl-migration followed by a ketol-acid reduction of (S)-2-acetolactate (S2AL) to yield (R)-2,3-dihydroxy-isovalerate. In the isomerase reaction, S2AL is rearranged via a Mg-dependent methyl migration to produce 3-hydroxy-3-methyl-2-ketobutyrate (HMKB). In the reductase reaction, this 2-ketoacid undergoes a metal-dependent reduction by NADPH to yield (R)-2,3-dihydroxy-isovalerate. Also able to use 2-ketopantoate, 2-ketoisovalerate, 2-ketovalerate, 2-ketobutyrate [...]
    
 0.975
folK
2-amino-4-hydroxy-6-hydroxymethyldihydropteridine diphosphokinase; Belongs to the HPPK family
  
 0.937
ilvE
Branched-chain amino acid aminotransferase; Acts on leucine, isoleucine and valine
    
 0.931
ilvD
Dihydroxy-acid dehydratase; Enzyme; Amino acid biosynthesis: Isoleucine, Valine
   
 
 0.926
guaA
Gmp synthetase (glutamine aminotransferase); Catalyzes the synthesis of GMP from XMP
 
   
 0.832
birA
Bira family transcriptional regulator, biotin operon repressor / biotin---[acetyl-coa-carboxylase] ligase; Acts both as a biotin--[acetyl-CoA-carboxylase] ligase and a biotin-operon repressor. In the presence of ATP, BirA activates biotin to form the BirA-biotinyl-5'-adenylate (BirA-bio-5'-AMP or holoBirA) complex. HoloBirA can either transfer the biotinyl moiety to the biotin carboxyl carrier protein (BCCP) subunit of acetyl-CoA carboxylase, or bind to the biotin operator site and inhibit transcription of the operon
     
 0.760
panM
Pand autocleavage accelerator, panothenate synthesis; Controls both the activation and catalytic activity of PanD in a coenzyme A (CoA)-dependent fashion. Binding of CoA or a derivative to PanZ leads to interaction with PanD, which promotes the processing and activation of pro-PanD, and subsequent substrate-mediated inhibition of the active form of PanD Inhibition of PanD activity is probably the primary metabolic role of PanZ, allowing negative feedback regulation of pantothenate biosynthesis by CoA
