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

yihWPutative transcriptional regulator for sulphoquinovose utilization; Involved in the regulation of the sulfoquinovose operon . Represses the expression of the yihUTS operon and of the yihV and csqR genes. Binds DNA inside the spacer between the bidirectional transcription units comprising the yihUTS operon and the yihV gene, and upstream the csqR gene itself (261 aa)    
Predicted Functional Partners:
yihV
6-deoxy-6-sulphofructose kinase; Phosphorylates 6-deoxy-6-sulfo-D-fructose (SF) to 6-deoxy-6- sulfo-D-fructose 1-phosphate (SFP)
 
  
 0.980
yihS
Sulfoquinovose isomerase; Catalyzes the isomerization of sulfoquinovose (SQ) to 6- deoxy-6-sulfo-D-fructose (SF). In vitro, can also catalyze the interconversion of mannose, fructose and glucose, or lyxose and xylulose, but has extremely low activity with glucose
 
   
 0.938
yihT
6-deoxy-6-sulphofructose-1-phosphate aldolase; Cleaves 6-deoxy-6-sulfo-D-fructose 1-phosphate (SFP) to form dihydroxyacetone phosphate (DHAP) and 3-sulfolactaldehyde (SLA)
 
   
 0.913
yihU
4-hydroxybutyrate dehydrogenase / sulfolactaldehyde 3-reductase; Reduces 3-sulfolactaldehyde (SLA) to 2,3-dihydroxypropane 1- sulfonate (DHPS)
     
 0.912
yihR
Putative sulphoquinovose mutarotase; Uncharacterized protein YihR; Putative aldose-1-epimerase
     
 0.872
yihQ
Putative sulpholipid alpha-glucosidase; Catalyzes the hydrolysis of sulfoquinovosyl diacylglycerides (SQDG) to sulfoquinovose (SQ), which is then degraded by E.coli through the SQ Embden-Meyerhof-Parnas (SQ-EMP) sulfoglycolysis pathway as a source of carbon and sulfur. Therefore, is likely involved in the utilization of the sulfoquinovose headgroup found in ubiquitous plant sulfolipids. Is also able to hydrolyze simple sulfoquinovosides such as 1-sulfoquinovosylglycerol (SQGro). Is a retaining glycoside hydrolase, since it forms the alpha anomer of SQ . Also exhibits some alpha-glucosi [...]

yegW
Uncharacterized HTH-type transcriptional regulator YegW; Putative transcriptional regulator; Protein involved in transcription repressor activity and transcription
      
 0.811
yihO
Glycoside/pentoside/hexuronide:cation symporter, gph family; Could be involved in sulfoquinovose import

dtd
D-aminoacyl-trna deacylase; An aminoacyl-tRNA editing enzyme that deacylates mischarged D-aminoacyl-tRNAs, has no observable editing activity on tRNAs charged with cognate L-amino acid Edits mischarged glycyl-tRNA(Ala) more efficiently than AlaRS . Acts via tRNA-based rather than protein-based catalysis Rejects correctly charged L-amino acid-tRNAs from its binding site rather than specifically recognizing incorrectly charged D-amino acid-tRNAs . Hydrolyzes correctly charged, achiral, glycyl-tRNA(Gly); GTP-bound EF-Tu (tested with T.thermophilus EF-Tu AC Q5SHN6) protects charged glycyl- [...]
