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

yqgEPutative transcriptional regulator; Similar to E. coli orf, hypothetical protein (AAC75985.1); Blastp hit to AAC75985.1 (211 aa), 92% identity in aa 25 - 211; Belongs to the UPF0301 (AlgH) family. (187 aa)    
Predicted Functional Partners:
yqgF
Putative endonuclease involved in recombination; Could be a nuclease involved in processing of the 5'-end of pre-16S rRNA; Belongs to the YqgF nuclease family.

nrdA
Ribonucleoside diphosphate reductase 1, alpha subunit; Provides the precursors necessary for DNA synthesis. Catalyzes the biosynthesis of deoxyribonucleotides from the corresponding ribonucleotides. R1 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.

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.

nadR
Trifunctional protein; This enzyme has three activities: DNA binding, nicotinamide mononucleotide (NMN) adenylyltransferase and ribosylnicotinamide (RN) kinase. The DNA-binding domain binds to the nadB operator sequence in an NAD- and ATP-dependent manner. As NAD levels increase within the cell, the affinity of NadR for the nadB operator regions of nadA, nadB, and pncB increases, repressing the transcription of these genes. The RN kinase activity catalyzes the phosphorylation of RN to form nicotinamide ribonucleotide. The NMN adenylyltransferase activity catalyzes the transfer of the A [...]

frdD
Fumarate reductase; Seems to be involved in the anchoring of the catalytic components of the fumarate reductase complex to the cytoplasmic membrane.
      
 0.892
frdC
Fumarate reductase; Seems to be involved in the anchoring of the catalytic components of the fumarate reductase complex to the cytoplasmic membrane.

blc
Outer membrane lipoprotein; Involved in the storage or transport of lipids necessary for membrane maintenance under stressful conditions. Displays a binding preference for lysophospholipids.
      
 0.767
sugE
Putative DMT superfamily transport protein; Guanidinium ion exporter. Couples guanidinium export to the proton motive force, exchanging one guanidinium ion for two protons. Belongs to the drug/metabolite transporter (DMT) superfamily. Small multidrug resistance (SMR) (TC 2.A.7.1) family. Gdx/SugE subfamily.
      
 0.764
dnaN
DNA polymerase III, beta-subunit; Confers DNA tethering and processivity to DNA polymerases and other proteins. Acts as a clamp, forming a ring around DNA (a reaction catalyzed by the clamp-loading complex) which diffuses in an ATP- independent manner freely and bidirectionally along dsDNA. Initially characterized for its ability to contact the catalytic subunit of DNA polymerase III (Pol III), a complex, multichain enzyme responsible for most of the replicative synthesis in bacteria; Pol III exhibits 3'-5' exonuclease proofreading activity. The beta chain is required for initiation of [...]
