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

tmkThymidylate kinase; Catalyzes the reversible phosphorylation of deoxythymidine monophosphate (dTMP) to deoxythymidine diphosphate (dTDP), using ATP as its preferred phosphoryl donor. Situated at the junction of both de novo and salvage pathways of deoxythymidine triphosphate (dTTP) synthesis, is essential for DNA synthesis and cellular growth; Belongs to the thymidylate kinase family. (213 aa)    
Predicted Functional Partners:
yceG
Septation protein, ampicillin sensitivity; Functions as a peptidoglycan terminase that cleaves nascent peptidoglycan strands endolytically to terminate their elongation. Belongs to the transglycosylase MltG family.

holB
DNA polymerase III, delta prime subunit; Part of the beta sliding clamp loading complex, which hydrolyzes ATP to load the beta clamp onto primed DNA to form the DNA replication pre-initiation complex. DNA polymerase III is a complex, multichain enzyme responsible for most of the replicative synthesis in bacteria. This DNA polymerase also exhibits 3' to 5' exonuclease activity. The gamma complex (gamma(3),delta,delta') is thought to load beta dimers onto DNA by binding ATP which alters the complex's conformation so it can bind beta sliding clamp dimers and open them at one interface.

pabC
4-amino-4-deoxychorismate lyase component of para-aminobenzoate synthase multienzyme complex; Involved in the biosynthesis of p-aminobenzoate (PABA), a precursor of tetrahydrofolate. Converts 4-amino-4-deoxychorismate into 4-aminobenzoate (PABA) and pyruvate; Belongs to the class-IV pyridoxal-phosphate-dependent aminotransferase family.
 
 
 0.982
tdk
Thymidine kinase/deoxyuridine kinase; Phosphorylates both thymidine and deoxyuridine.
  
 
 0.982
dut
Deoxyuridinetriphosphatase; This enzyme is involved in nucleotide metabolism: it produces dUMP, the immediate precursor of thymidine nucleotides and it decreases the intracellular concentration of dUTP so that uracil cannot be incorporated into DNA.
  
 
 0.973
thyA
Thymidylate synthetase; Catalyzes the reductive methylation of 2'-deoxyuridine-5'- monophosphate (dUMP) to 2'-deoxythymidine-5'-monophosphate (dTMP) while utilizing 5,10-methylenetetrahydrofolate (mTHF) as the methyl donor and reductant in the reaction, yielding dihydrofolate (DHF) as a by-product. This enzymatic reaction provides an intracellular de novo source of dTMP, an essential precursor for DNA biosynthesis. This protein also binds to its mRNA thus repressing its own translation.
  
 
 0.972
ycfH
Putative DNase; Has D-tyrosyl-tRNA deacylase activity in vitro.
 
  
 0.947
acpP
Acyl carrier protein (ACP); Carrier of the growing fatty acid chain in fatty acid biosynthesis; Belongs to the acyl carrier protein (ACP) family.
 
  
 0.946
nrdE
Ribonucleoside-diphosphate reductase 2, alpha subunit; Provides the precursors necessary for DNA synthesis. Catalyzes the biosynthesis of deoxyribonucleotides from the corresponding ribonucleotides. R1E contains the binding sites for both substrates and allosteric effectors and carries out the actual reduction of the ribonucleotide; Belongs to the ribonucleoside diphosphate reductase large chain family.
  
 
 0.939
ndk
Nucleoside diphosphate kinase; Major role in the synthesis of nucleoside triphosphates other than ATP. The ATP gamma phosphate is transferred to the NDP beta phosphate via a ping-pong mechanism, using a phosphorylated active-site intermediate.
