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

diaADnaA initiator-associating factor for replication initiation; Required for the timely initiation of chromosomal replication via direct interactions with the DnaA initiator protein. (196 aa)    
Predicted Functional Partners:
gmhB
D,D-heptose 1,7-bisphosphate phosphatase; Converts the D-glycero-beta-D-manno-heptose 1,7-bisphosphate (beta-HBP) intermediate into D-glycero-beta-D-manno-heptose 1-phosphate by removing the phosphate group at the C-7 position.
  
 0.982
dnaA
Chromosomal replication initiator protein DnaA, DNA-binding transcriptional dual regulator; Plays a key role in the initiation and regulation of chromosomal replication. Binds in an ATP-dependent fashion to the origin of replication (oriC) to initiate formation of the DNA replication initiation complex exactly once per cell cycle. Binds the DnaA box (consensus sequence 5'-TTATC[CA]A[CA]A-3'); subsequent binding of DNA polymerase III subunits leads to replisome formation. The DnaA- ATP form converts to DnaA-ADP; once converted to ADP the protein cannot initiate replication, ensuring onl [...]

yraP
Outer membrane lipoprotein; Putative periplasmic protein.
 
    0.945
hldE
Heptose 7-phosphate kinase and heptose 1-phosphate adenyltransferase; Catalyzes the phosphorylation of D-glycero-D-manno-heptose 7- phosphate at the C-1 position to selectively form D-glycero-beta-D- manno-heptose-1,7-bisphosphate; In the N-terminal section; belongs to the carbohydrate kinase PfkB family.
  
 0.939
lpoA
OM lipoprotein stimulator of MrcA transpeptidase; Regulator of peptidoglycan synthesis that is essential for the function of penicillin-binding protein 1A (PBP1a). Stimulates transpeptidase activity of PBP1a in vitro.
 
    0.900
hda
ATPase regulatory factor involved in DnaA inactivation; Mediates the interactions of DNA replication initiator protein DnaA with DNA polymerase subunit beta sliding clamp (dnaN). Stimulates hydrolysis of ATP-DnaA to ADP-DnaA, rendering DnaA inactive for reinitiation, a process called regulatory inhibition of DnaA or RIDA. ADP-binding activates Hda to hydrolyze DnaA-ATP; Hda monomers bind to ADP with about 200-fold greater affinity than for ATP. RIDA function can be genetically separated from viability, suggesting this protein has another function as well.

yraN
UPF0102 family protein; Belongs to the UPF0102 family.
 
  
 0.871
hisB
Imidazoleglycerolphosphate dehydratase and histidinol-phosphate phosphatase; Protein involved in histidine biosynthetic process.
  
  
 0.781
waaQ
Lipopolysaccharide core biosynthesis protein; Catalyzes heptose transfer to the lipopolysaccharide core. It transfers a heptose, called heptose(III), to the heptose(II) of the inner core (By similarity); Belongs to the glycosyltransferase 9 family.
 
   
 0.741
waaF
ADP-heptose--lps heptosyltransferase II; lipopolysaccharide core biosynthesis; Protein involved in cell surface antigen activity, host-interacting and lipopolysaccharide core region biosynthetic process.
