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

sulASuppressor of lon; Component of the SOS system and an inhibitor of cell division. Accumulation of SulA causes rapid cessation of cell division and the appearance of long, non-septate filaments. In the presence of GTP, binds a polymerization-competent form of FtsZ in a 1:1 ratio, thus inhibiting FtsZ polymerization and therefore preventing it from participating in the assembly of the Z ring. This mechanism prevents the premature segregation of damaged DNA to daughter cells during cell division. (169 aa)

lolAPeriplasmic protein; Participates in the translocation of lipoproteins from the inner membrane to the outer membrane. Only forms a complex with a lipoprotein if the residue after the N-terminal Cys is not an aspartate (The Asp acts as a targeting signal to indicate that the lipoprotein should stay in the inner membrane). (204 aa)
dinGLexA regulated (SOS) repair enzyme; DNA-dependent ATPase and 5'-3' DNA helicase. (714 aa)
ahpCAlkyl hydroperoxide reductase, C22 subunit; Thiol-specific peroxidase that catalyzes the reduction of hydrogen peroxide and organic hydroperoxides to water and alcohols, respectively. Plays a role in cell protection against oxidative stress by detoxifying peroxides; Belongs to the peroxiredoxin family. AhpC/Prx1 subfamily. (187 aa)
impOrganic solvent tolerance protein; Together with LptE, is involved in the assembly of lipopolysaccharide (LPS) at the surface of the outer membrane. (786 aa)
trxBSimilar to E. coli thioredoxin reductase (AAC73974.1); Blastp hit to AAC73974.1 (321 aa), 96% identity in aa 1 - 320. (322 aa)
murGUndecaprenyldiphospho-muramoylpentapeptide beta-N-acetylglucosaminyltransferase; Cell wall formation. Catalyzes the transfer of a GlcNAc subunit on undecaprenyl-pyrophosphoryl-MurNAc-pentapeptide (lipid intermediate I) to form undecaprenyl-pyrophosphoryl-MurNAc- (pentapeptide)GlcNAc (lipid intermediate II); Belongs to the glycosyltransferase 28 family. MurG subfamily. (355 aa)
lexASOS response regulator; Represses a number of genes involved in the response to DNA damage (SOS response), including recA and lexA. Binds to the 16 bp palindromic sequence 5'-CTGTATATATATACAG-3'. In the presence of single- stranded DNA, RecA interacts with LexA causing an autocatalytic cleavage which disrupts the DNA-binding part of LexA, leading to derepression of the SOS regulon and eventually DNA repair. (202 aa)
rplU50S ribosomal subunit protein L21; This protein binds to 23S rRNA in the presence of protein L20; Belongs to the bacterial ribosomal protein bL21 family. (103 aa)
rpmASimilar to E. coli 50S ribosomal subunit protein L27 (AAC76217.1); Blastp hit to AAC76217.1 (85 aa), 95% identity in aa 1 - 85; Belongs to the bacterial ribosomal protein bL27 family. (85 aa)
relA(p)ppGpp synthetase I; In eubacteria ppGpp (guanosine 3'-diphosphate 5-' diphosphate) is a mediator of the stringent response that coordinates a variety of cellular activities in response to changes in nutritional abundance. (744 aa)
recADNA strand exchange and recombination protein; Can catalyze the hydrolysis of ATP in the presence of single- stranded DNA, the ATP-dependent uptake of single-stranded DNA by duplex DNA, and the ATP-dependent hybridization of homologous single-stranded DNAs. It interacts with LexA causing its activation and leading to its autocatalytic cleavage. (353 aa)
STM2804Putative cytoplasmic protein; Antioxidant protein with alkyl hydroperoxidase activity. Required for the reduction of the AhpC active site cysteine residues and for the regeneration of the AhpC enzyme activity. Belongs to the AhpD family. (143 aa)
yfhPHypothetical protein; Regulates the transcription of several operons and genes involved in the biogenesis of Fe-S clusters and Fe-S-containing proteins. (164 aa)
nifSPutative aminotransferase class-V; Master enzyme that delivers sulfur to a number of partners involved in Fe-S cluster assembly, tRNA modification or cofactor biosynthesis. Catalyzes the removal of elemental sulfur and selenium atoms from cysteine and selenocysteine to produce alanine. Functions as a sulfur delivery protein for Fe-S cluster synthesis onto IscU, an Fe-S scaffold assembly protein, as well as other S acceptor proteins. Also functions as a selenium delivery protein in the pathway for the biosynthesis of selenophosphate; Belongs to the class-V pyridoxal-phosphate-dependent [...] (404 aa)
hscBCo-chaperone protein Hsc20; Co-chaperone involved in the maturation of iron-sulfur cluster-containing proteins. Seems to help targeting proteins to be folded toward HscA; Belongs to the HscB family. (171 aa)
hscAChaperone protein; Chaperone involved in the maturation of iron-sulfur cluster- containing proteins. Has a low intrinsic ATPase activity which is markedly stimulated by HscB. Involved in the maturation of IscU. (616 aa)
nuoHNADH dehydrogenase I chain H; NDH-1 shuttles electrons from NADH, via FMN and iron-sulfur (Fe-S) centers, to quinones in the respiratory chain. The immediate electron acceptor for the enzyme in this species is believed to be ubiquinone. Couples the redox reaction to proton translocation (for every two electrons transferred, four hydrogen ions are translocated across the cytoplasmic membrane), and thus conserves the redox energy in a proton gradient. This subunit may bind ubiquinone. (325 aa)
otsBTrehalose-6-phosphate phophatase, biosynthetic; Removes the phosphate from trehalose 6-phosphate to produce free trehalose. (267 aa)
otsATrehalose-6-phosphate synthase; Probably involved in the osmoprotection via the biosynthesis of trehalose. Catalyzes the transfer of glucose from UDP-alpha-D- glucose (UDP-Glc) to D-glucose 6-phosphate (Glc-6-P) to form trehalose- 6-phosphate. Acts with retention of the anomeric configuration of the UDP-sugar donor; Belongs to the glycosyltransferase 20 family. (473 aa)
