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.

birABifunctional protein, biotin operon repressor; Acts both as a biotin--[acetyl-CoA-carboxylase] ligase and a repressor; Belongs to the biotin--protein ligase family. (311 aa)    
Predicted Functional Partners:
smi_1676
acetyl-CoA carboxylase biotin carboxylase subunit; This protein is a component of the acetyl coenzyme A carboxylase complex; first, biotin carboxylase catalyzes the carboxylation of the carrier protein and then the transcarboxylase transfers the carboxyl group to form malonyl-CoA.
 
  
 0.962
metK
S-adenosylmethionine synthetase; Catalyzes the formation of S-adenosylmethionine (AdoMet) from methionine and ATP. The overall synthetic reaction is composed of two sequential steps, AdoMet formation and the subsequent tripolyphosphate hydrolysis which occurs prior to release of AdoMet from the enzyme.
  
  
 0.901
smi_0834
Conserved hypothetical protein.
 
   
 0.883
sulD
Aldolase-pyrophosphokinase; Catalyzes the conversion of 7,8-dihydroneopterin to 6- hydroxymethyl-7,8-dihydropterin.
  
  
 0.879
smi_1350
Conserved hypothetical protein.
  
 0.874
pcnB
tRNA nucleotidyltransferase; Catalyzes the addition and repair of the essential 3'- terminal CCA sequence in tRNAs without using a nucleic acid template. Adds these three nucleotides in the order of C, C, and A to the tRNA nucleotide-73, using CTP and ATP as substrates and producing inorganic pyrophosphate.
 
  
 0.866
smi_1953
Molecular chaperone; COG1214, inactive homolog of metal-dependent proteases.
 
    0.844
guaB
Inosine monophosphate dehydrogenase; Catalyzes the conversion of inosine 5'-phosphate (IMP) to xanthosine 5'-phosphate (XMP), the first committed and rate-limiting step in the de novo synthesis of guanine nucleotides, and therefore plays an important role in the regulation of cell growth. Belongs to the IMPDH/GMPR family.
  
  
 0.830
murB
UDP-N-acetylenolpyruvoylglucosamine reductase; Cell wall formation.
  
  
 0.820
pyrR
Pyrimidine operon regulatory protein; Also displays a weak uracil phosphoribosyltransferase activity which is not physiologically significant; Belongs to the purine/pyrimidine phosphoribosyltransferase family. PyrR subfamily.
