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
Your Input:
tolRTol protein, role in outer membrane integrity; Part of the Tol-Pal system, which plays a role in outer membrane invagination during cell division and is important for maintaining outer membrane integrity. Required, with TolQ, for the proton motive force-dependent activation of TolA and for TolA-Pal interaction. (142 aa)
tolQTol protein, membrane-spanning inner membrane protein; Part of the Tol-Pal system, which plays a role in outer membrane invagination during cell division and is important for maintaining outer membrane integrity. Required, with TolR, for the proton motive force-dependent activation of TolA and for TolA-Pal interaction. (230 aa)
yafKPutative periplasmic protein; Similar to E. coli orf, hypothetical protein (AAC73328.1); Blastp hit to AAC73328.1 (246 aa), 90% identity in aa 1 - 246. (246 aa)
htrAPeriplasmic serine protease Do, heat shock protein; DegP acts as a chaperone at low temperatures but switches to a peptidase (heat shock protein) at higher temperatures. It degrades transiently denatured and unfolded proteins which accumulate in the periplasm following heat shock or other stress conditions. DegP is efficient with Val-Xaa and Ile-Xaa peptide bonds, suggesting a preference for beta-branched side chain amino acids. Only unfolded proteins devoid of disulfide bonds appear capable of being cleaved, thereby preventing non-specific proteolysis of folded proteins. Its proteolyt [...] (475 aa)
mrcBTranspeptidase of penicillin-binding protein 1b; Cell wall formation. Synthesis of cross-linked peptidoglycan from the lipid intermediates. The enzyme has a penicillin-insensitive transglycosylase N-terminal domain (formation of linear glycan strands) and a penicillin-sensitive transpeptidase C-terminal domain (cross- linking of the peptide subunits). (840 aa)
ftsZTubulin-like GTP-binding protein and GTPase; Essential cell division protein that forms a contractile ring structure (Z ring) at the future cell division site. The regulation of the ring assembly controls the timing and the location of cell division. One of the functions of the FtsZ ring is to recruit other cell division proteins to the septum to produce a new cell wall between the dividing cells. Binds GTP and shows GTPase activity. (383 aa)
rfaCHeptosyl transferase I; Heptose transfer to the lipopolysaccharide core. It transfers the innermost heptose to [4'-P](3-deoxy-D-manno-octulosonic acid)2-IVA; Belongs to the glycosyltransferase 9 family. (317 aa)
ftsXPutative integral membrane cell division protein; Part of the ABC transporter FtsEX involved in cellular division; Belongs to the ABC-4 integral membrane protein family. FtsX subfamily. (351 aa)
degSPeriplasmic serine endoprotease; Similar to E. coli protease (AAC76267.1); Blastp hit to AAC76267.1 (355 aa), 91% identity in aa 1 - 355. (356 aa)
nlpILipoprotein, cell division; May be involved in cell division. May play a role in bacterial septation or regulation of cell wall degradation during cell division (By similarity). (294 aa)
rfaEPutative sugar nucleotide transferase domain of ADP-L-glycero-D-manno-heptose synthase; 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. (477 aa)
fljBFilament structural protein; Flagellin is the subunit protein which polymerizes to form the filaments of bacterial flagella. (506 aa)
rseAAnti sigma E (sigma 24) factor, negative regulator; An anti-sigma factor for extracytoplasmic function (ECF) sigma factor sigma-E (RpoE). ECF sigma factors are held in an inactive form by an anti-sigma factor until released by regulated intramembrane proteolysis (RIP). RIP occurs when an extracytoplasmic signal triggers a concerted proteolytic cascade to transmit information and elicit cellular responses. The membrane-spanning regulatory substrate protein is first cut periplasmically (site-1 protease, S1P, DegS), then within the membrane itself (site-2 protease, S2P, RseP), while cytop [...] (216 aa)
fliCFlagellar biosynthesis; Flagellin is the subunit protein which polymerizes to form the filaments of bacterial flagella. (495 aa)
lppMurein lipoprotein; Plays an important role in virulence. A highly abundant outer membrane lipoprotein that controls the distance between the inner and outer membranes. The only protein known to be covalently linked to the peptidoglycan network (PGN). Also non- covalently binds the PGN. The link between the cell outer membrane and PGN contributes to maintenance of the structural and functional integrity of the cell envelope, and maintains the correct distance between the PGN and the outer membrane (By similarity). (78 aa)
lppBPutative methyl-accepting chemotaxis protein; Plays an important role in virulence. A highly abundant outer membrane lipoprotein that controls the distance between the inner and outer membranes. The only protein known to be covalently linked to the peptidoglycan network (PGN). Also non- covalently binds the PGN. The link between the cell outer membrane and PGN contributes to maintenance of the structural and functional integrity of the cell envelope, and maintains the correct distance between the PGN and the outer membrane (By similarity). (79 aa)
nlpCLipoprotein; Similar to E. coli lipoprotein (AAC74778.1); Blastp hit to AAC74778.1 (154 aa), 86% identity in aa 1 - 154. (154 aa)
ompAPutative membrane component hydrogenase; With TolR probably plays a role in maintaining the position of the peptidoglycan cell wall in the periplasm. Acts as a porin with low permeability that allows slow penetration of small solutes; an internal gate slows down solute passage. (350 aa)
tolBTol protein required for outer membrane integrity; Part of the Tol-Pal system, which plays a role in outer membrane invagination during cell division and is important for maintaining outer membrane integrity. TolB occupies a key intermediary position in the Tol-Pal system because it communicates directly with both membrane-embedded components, Pal in the outer membrane and TolA in the inner membrane. (430 aa)
