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

yhcKPutative gntR family regulatory protein; Transcriptional repressor that controls expression of the genes required for the catabolism of sialic acids. (263 aa)    
Predicted Functional Partners:
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.
 
   
 0.971
nanA
N-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.
 
   
 0.959
nanE
Putative ManNAc-6P epimerase; Converts N-acetylmannosamine-6-phosphate (ManNAc-6-P) to N- acetylglucosamine-6-phosphate (GlcNAc-6-P).
 
   
 0.942
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.
     
 0.922
nanK
Putative ManNAc kinase; Catalyzes the phosphorylation of N-acetylmannosamine (ManNAc) to ManNAc-6-P; Belongs to the ROK (NagC/XylR) family. NanK subfamily.
 
   
 0.901
lldR
Putative transcriptional GntR family regulator for lct operon; Similar to E. coli transcriptional regulator (AAC76628.1); Blastp hit to AAC76628.1 (258 aa), 86% identity in aa 1 - 258.
  
     0.772
nagB
Glucosamine-6-phosphate deaminase; Catalyzes the reversible isomerization-deamination of glucosamine 6-phosphate (GlcN6P) to form fructose 6-phosphate (Fru6P) and ammonium ion.
     
 0.769
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.
     
 0.755
nagC
Similar to E. coli transcriptional repressor of nag (N-acetylglucosamine) operon (AAC73770.1); Blastp hit to AAC73770.1 (406 aa), 94% identity in aa 1 - 406.
     
 0.671
STM3357
Putative gntR family regulatory protein; Similar to E. coli orf, hypothetical protein (AAC74613.1); Blastp hit to AAC74613.1 (228 aa), 23% identity in aa 15 - 214.
