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:
sigLRNA polymerase sigma-54 factor (sigma-L); Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This sigma factor is responsible for the expression of the levanase operon. The open complex (sigma-54 and core RNA polymerase) serves as the receptor for receipt of the melting signal from the remotely bound activator protein LevR for the expression of the levanase operon. (436 aa)
nagRTranscriptional regulator (GntR family); Main transcriptional repressor of genes involved in N- acetylglucosamine (GlcNAc) transport and utilization. Represses the expression of the nagAB and nagP operons by binding directly within their upstream regions. Binds to the DNA consensus sequence 5'-ATTGGTATAGACAACT-3'. Also acts as a weak repressor of mapB expression. (243 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)
pepTPeptidase T (tripeptidase); Cleaves the N-terminal amino acid of tripeptides. Belongs to the peptidase M20B family. (410 aa)
pdpPyrimidine-nucleoside phosphorylase; Catalyzes phosphorolysis of the pyrimidine nucleosides uridine, thymidine and 2'-deoxyuridine with the formation of the corresponding pyrimidine base and ribose-1-phosphate. (433 aa)
nupCPyrimidine-nucleoside Na+(H+) cotransporter; Transport of the pyrimidine nucleoside uridine. (393 aa)
gntRTranscriptional regulator (GntR family); Transcriptional repressor of the gluconate operon (gntRKPZ), which encodes the proteins for gluconate utilization. Represses mRNA synthesis by binding to the gnt operator; the binding is suppressed by gluconate or glucono-delta-lactone. (243 aa)
ccpATranscriptional regulator (Lacl family); Global transcriptional regulator of carbon catabolite repression (CCR) and carbon catabolite activation (CCA), which ensures optimal energy usage under diverse conditions. Interacts with either P- Ser-HPr or P-Ser-Crh, leading to the formation of a complex that binds to DNA at the catabolite-response elements (cre). Binding to DNA allows activation or repression of many different genes and operons. (334 aa)
pgiGlucose-6-phosphate isomerase; Evidence 2a: Function of homologous gene experimentally demonstrated in an other organism; Product type e: enzyme; Belongs to the GPI family. (450 aa)
nagBAN-acetylglucosamine-6-phosphate isomerase; Catalyzes the reversible isomerization-deamination of glucosamine 6-phosphate (GlcN6P) to form fructose 6-phosphate (Fru6P) and ammonium ion; Belongs to the glucosamine/galactosamine-6-phosphate isomerase family. NagB subfamily. (242 aa)
bofAInhibitor of the pro-sigma(K) processing machinery; Involved in the mediation of the intercompartmental coupling of pro-sigma K processing to events in the forespore. Inhibits SpoIVFB- processing activity until a signal has been received from the forespore. Could inhibit SpoIVFB metalloprotease activity by coordinating a zinc in the SpoIVFB active site, preventing access of a water molecule and the sequence of pro-sigma K, which are necessary for peptide bond hydrolysis to produce sigma-K. (87 aa)
gamPPhosphotransferase system (PTS) glucosamine-specific enzyme IICBA component; The phosphoenolpyruvate-dependent sugar phosphotransferase system (sugar PTS), a major carbohydrate active transport system, catalyzes the phosphorylation of incoming sugar substrates concomitantly with their translocation across the cell membrane. This system may be involved in glucosamine transport. (631 aa)
nagPPhosphotransferase system (PTS) N-acetylglucosamine-specific enzyme IICB component; The phosphoenolpyruvate-dependent sugar phosphotransferase system (sugar PTS), a major carbohydrate active -transport system, catalyzes the phosphorylation of incoming sugar substrates concomitantly with their translocation across the cell membrane. This system is involved in N-acetylglucosamine transport (By similarity). (452 aa)
ptsGPhosphotransferase system (PTS) glucose-specific enzyme IICBA component; The phosphoenolpyruvate-dependent sugar phosphotransferase system (sugar PTS), a major carbohydrate active transport system, catalyzes the phosphorylation of incoming sugar substrates concomitantly with their translocation across the cell membrane. This system is involved in glucose transport. (699 aa)
ptsHHistidine-containing phosphocarrier protein of the phosphotransferase system (PTS) (HPr protein); General (non sugar-specific) component of the phosphoenolpyruvate-dependent sugar phosphotransferase system (sugar PTS). This major carbohydrate active-transport system catalyzes the phosphorylation of incoming sugar substrates concomitantly with their translocation across the cell membrane. The phosphoryl group from phosphoenolpyruvate (PEP) is transferred to the phosphoryl carrier protein HPr by enzyme I. Phospho-HPr then transfers it to the PTS EIIA domain. (88 aa)
ptsIPhosphotransferase system (PTS) enzyme I; General (non sugar-specific) component of the phosphoenolpyruvate-dependent sugar phosphotransferase system (sugar PTS). This major carbohydrate active-transport system catalyzes the phosphorylation of incoming sugar substrates concomitantly with their translocation across the cell membrane. Enzyme I transfers the phosphoryl group from phosphoenolpyruvate (PEP) to the phosphoryl carrier protein (HPr). (570 aa)
nprEExtracellular neutral metalloprotease; Extracellular zinc metalloprotease; Belongs to the peptidase M4 family. (521 aa)
cddCytidine/deoxycytidine deaminase; This enzyme scavenges exogenous and endogenous cytidine and 2'-deoxycytidine for UMP synthesis. (136 aa)
ackAAcetate kinase; Catalyzes the formation of acetyl phosphate from acetate and ATP. Can also catalyze the reverse reaction. Appears to favor the formation of acetate. Involved in the secretion of excess carbohydrate. (395 aa)
