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

nanAN-acetylneuraminate lyase; Catalyzes the reversible aldol cleavage of N-acetylneuraminic acid (sialic acid; Neu5Ac) to form pyruvate and N-acetylmannosamine (ManNAc) via a Schiff base intermediate. (297 aa)    
Predicted Functional Partners:
nanK
Putative ManNAc kinase; Catalyzes the phosphorylation of N-acetylmannosamine (ManNAc) to ManNAc-6-P; Belongs to the ROK (NagC/XylR) family. NanK subfamily.
 
 
 0.998
nanE
Putative ManNAc-6P epimerase; Converts N-acetylmannosamine-6-phosphate (ManNAc-6-P) to N- acetylglucosamine-6-phosphate (GlcNAc-6-P).
 
  
 0.994
nanT
MFS family sialic acid transport protein; Catalyzes the proton-dependent transport of sialic acid. Belongs to the major facilitator superfamily. Sialate:H(+) symporter (SHS) (TC 2.A.1.12) family.
 
  
 0.993
yhcK
Putative gntR family regulatory protein; Transcriptional repressor that controls expression of the genes required for the catabolism of sialic acids.
 
   
 0.959
nanH
Sialidase; Cleaves the terminal sialic acid (N-acetyl neuraminic acid) from carbohydrate chains in glycoproteins providing free sialic acid which can be used as carbon and energy sources. Sialidases have been suggested to be pathogenic factors in microbial infections.
 
   
 0.953
yhcH
Putative cytoplasmic protein; Similar to E. coli orf, hypothetical protein (AAC76253.1); Blastp hit to AAC76253.1 (154 aa), 80% identity in aa 1 - 154.
 
  
 0.937
nanM
Putative inner membrane protein; Converts alpha-N-acetylneuranimic acid (Neu5Ac) to the beta- anomer, accelerating the equilibrium between the alpha- and beta- anomers. Probably facilitates sialidase-negative bacteria to compete sucessfully for limited amounts of extracellular Neu5Ac, which is likely taken up in the beta-anomer. In addition, the rapid removal of sialic acid from solution might be advantageous to the bacterium to damp down host responses; Belongs to the NanM family.
  
  
 0.903
STM1128
Similar to E. coli putative cotransporter (AAC76702.1); Blastp hit to AAC76702.1 (571 aa), 22% identity in aa 7 - 478; Belongs to the sodium:solute symporter (SSF) (TC 2.A.21) family.
 
  
 0.862
STM1617
Putative ribulose-phosphate 3-epimerase; Similar to E. coli putative epimerase (AAC77257.1); Blastp hit to AAC77257.1 (210 aa), 65% identity in aa 1 - 210.
  
  
 0.846
dapB
Dihydrodipicolinate reductase; Catalyzes the conversion of 4-hydroxy-tetrahydrodipicolinate (HTPA) to tetrahydrodipicolinate; Belongs to the DapB family.
 
  
 0.845
