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:
yaaNConserved hypothetical protein; Evidence 4: Homologs of previously reported genes of unknown function; PubMedId: 12533473; Belongs to the TelA family. (386 aa)
sigWRNA polymerase ECF(extracytoplasmic function)-type sigma factor W; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. Sigma-W controls genes involved in response to cell envelope stress such as antimicrobial peptides , alkaline pH , transport processes and detoxification. (187 aa)
rsiWanti-sigma(W) factor; The anti-sigma factor for extracytoplasmic function (ECF) sigma factor sigma-W (SigW). Holds SigW, its cognate ECF sigma factor, in an inactive form until released by regulated intramembrane proteolysis (RIP). SigW and RsiW mediate cell response to cell wall stress. 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, PrsW) , then within the membrane itself (site-2 protease, S2P [...] (208 aa)
yceGConserved hypothetical protein; Evidence 4: Homologs of previously reported genes of unknown function. (537 aa)
yceHConserved hypothetical protein; Evidence 4: Homologs of previously reported genes of unknown function; Belongs to the TelA family. (363 aa)
naiPNiacin permease; Probably involved in the uptake of amidated and deamidated forms of niacin. Increases the growth rate of E.coli that is unable to make niacin de novo; confers increased sensitivity to the toxic niacin analog 6-amino-nicotinamide to wild-type E.coli. There is probably another mechanism for niacin uptake. (400 aa)
pspAPhage shock protein A homolog; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type h: extrachromosomal origin. (227 aa)
ltaSAExported glycerol phosphate lipoteichoic acid synthetase and anion-binding protein; Catalyzes the polymerization of lipoteichoic acid (LTA) polyglycerol phosphate, a reaction that presumably uses phosphatidylglycerol (PG) as substrate. (639 aa)
sigMRNA polymerase ECF (extracytoplasmic function)-type sigma factor (sigma(M)); Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. Extracytoplasmic function (ECF) sigma factors are held in an inactive form by a cognate anti-sigma factor (YhdL) until released. This sigma factor is involved in the maintenance of membrane and cell wall integrity in response to environmental stresses including salt, acid, ethanol and antibiotics stress. Partially regulates transcription from a number of genes including disA. (163 aa)
sigXRNA polymerase ECF(extracytoplasmic function)-type sigma factor sigma(X); Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. May be involved in the regulation of iron metabolism; Belongs to the sigma-70 factor family. ECF subfamily. (194 aa)
ltaSCEnzyme responsible for polyglycerolphosphate LTA synthesis; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type e: enzyme; Belongs to the LTA synthase family. (638 aa)
yqeZPutative membrane bound hydrolase; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pe: putative enzyme. (437 aa)
sppASignal peptide peptidase; Digestion of cleaved signal peptides (By similarity). Required for efficient processing of precursors under conditions of hyper-secretion. Has a preference for leucine-rich substrate peptides. Belongs to the peptidase S49 family. (335 aa)
liaSTwo-component sensor histidine kinase [YvqC] sensing cell wall stress; Member of the two-component regulatory system LiaS/LiaR probably involved in response to a subset of cell wall-active antibiotics that interfere with the lipid II cycle in the cytoplasmic membrane (bacitracin, nisin, ramoplanin and vancomycin). Seems also involved in response to cationic antimicrobial peptides and secretion stress. Activates probably LiaR by phosphorylation. (360 aa)
liaRTwo-component response regulator [YvqE] responding to cell wall stress; Member of the two-component regulatory system LiaS/LiaR probably involved in response to a subset of cell wall-active antibiotics that interfere with the lipid II cycle in the cytoplasmic membrane (bacitracin, nisin, ramoplanin and vancomycin). Seems also involved in response to cationic antimicrobial peptides and secretion stress. LiaR regulates the transcription of the liaIHGFSR operon. (211 aa)
liaHModulator of liaIHGFSR (yvqIHGFEC) operon expression; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type f: factor. (225 aa)
dltAD-alanine:D-alanyl-carrier protein ligase; Catalyzes the first step in the D-alanylation of lipoteichoic acid (LTA), the activation of D-alanine and its transfer onto the D- alanyl carrier protein (Dcp) DltC. In an ATP-dependent two-step reaction, forms a high energy D-alanyl-AMP intermediate, followed by transfer of the D-alanyl residue as a thiol ester to the phosphopantheinyl prosthetic group of the Dcp. D-alanylation of LTA plays an important role in modulating the properties of the cell wall in Gram-positive bacteria, influencing the net charge of the cell wall. Belongs to the ATP [...] (503 aa)
ywtFPutative transcriptional regulator; May catalyze the final step in cell wall teichoic acid biosynthesis, the transfer of the anionic cell wall polymers (APs) from their lipid-linked precursor to the cell wall peptidoglycan (PG). (322 aa)
lytRMembrane-bound transcriptional regulator; May catalyze the final step in cell wall teichoic acid biosynthesis, the transfer of the anionic cell wall polymers (APs) from their lipid-linked precursor to the cell wall peptidoglycan (PG). (306 aa)
