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

alrAlanine racemase; Catalyzes the interconversion of L-alanine and D-alanine. This organism is able to use both L- and D-alanine as a nitrogen source. May also prevent D-alanine from interfering with the use of L- alanine. (373 aa)    
Predicted Functional Partners:
ald
Alanine dehydrogenase; Catalyzes the reversible reductive amination of pyruvate to L-alanine. This enzyme is a key factor in the assimilation of L-alanine as an energy source through the tricarboxylic acid cycle. Belongs to the AlaDH/PNT family.
  
  
 0.996
agcS
Sodium:alanine symporter; Probably functions as a sodium/L- and D-alanine symporter for alanine uptake.
     
 0.862
hpt
Hypoxanthine (guanine) phosphoribosyltransferase; Catalyzes a salvage reaction resulting in the formation of IMP that is energically less costly than de novo synthesis. Belongs to the purine/pyrimidine phosphoribosyltransferase family. Archaeal HPRT subfamily.
  
  
 0.717
MMP0173
Conserved hypothetical protein.
     
 0.710
dapB
Dihydrodipicolinate reductase; Catalyzes the conversion of 4-hydroxy-tetrahydrodipicolinate (HTPA) to tetrahydrodipicolinate.
  
 
 0.656
ilvE
Aminotransferase (subgroup III) similar to Branched-chain amino acid aminotransferase; Acts on leucine, isoleucine and valine. Belongs to the class-IV pyridoxal-phosphate-dependent aminotransferase family.
  
  
 0.642
lysC
Aspartate kinase; Citation: Tang G, Zhu-Shimoni JX, Amir R, Zchori IB, Galili G. (1997) Plant Mol Biol 34:287-93; Belongs to the aspartokinase family.
     
 0.629
upp
Uracil Phosphoribosyltransferase; Catalyzes the conversion of uracil and 5-phospho-alpha-D- ribose 1-diphosphate (PRPP) to UMP and diphosphate; Belongs to the UPRTase family.
     
 0.614
dapA
Dihydrodipicolinate synthase; Catalyzes the condensation of (S)-aspartate-beta-semialdehyde [(S)-ASA] and pyruvate to 4-hydroxy-tetrahydrodipicolinate (HTPA).
     
 0.604
dapF
Diaminopimelate epimerase; Catalyzes the stereoinversion of LL-2,6-diaminoheptanedioate (L,L-DAP) to meso-diaminoheptanedioate (meso-DAP), a precursor of L- lysine.
     
 0.584
