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:
phoEOuter membrane porin PhoE; Uptake of inorganic phosphate, phosphorylated compounds, and some other negatively charged solutes; Belongs to the Gram-negative porin family. (351 aa)
acrRTranscriptional repressor; Potential regulator protein for the acrAB genes. (215 aa)
macBMacrolide ABC transporter peremase/ATPase; Part of the tripartite efflux system MacAB-TolC. MacB is a non-canonical ABC transporter that contains transmembrane domains (TMD), which form a pore in the inner membrane, and an ATP-binding domain (NBD), which is responsible for energy generation. When overexpressed, the system confers resistance against macrolides composed of 14- and 15-membered lactones but no or weak resistance against 16-membered ones. In addition, the system could also transport R-LPS or a similar glycolipid. Belongs to the ABC transporter superfamily. Macrolide exporte [...] (648 aa)
lolCLipoprotein-releasing system transmembrane protein; Part of an ATP-dependent transport system LolCDE responsible for the release of lipoproteins targeted to the outer membrane from the inner membrane. Such a release is dependent of the sorting-signal (absence of an Asp at position 2 of the mature lipoprotein) and of LolA. (399 aa)
tonBMembrane spanning protein in TonB-ExbB-ExbD transport complex; Interacts with outer membrane receptor proteins that carry out high-affinity binding and energy dependent uptake into the periplasmic space of specific substrates such as cobalamin, and various iron compounds (such as iron dicitrate, enterochelin, aerobactin, etc.). In the absence of TonB these receptors bind their substrates but do not carry out active transport. TonB also interacts with some colicins and is involved in the energy-dependent, irreversible steps of bacteriophages phi 80 and T1 infection. It could act to tran [...] (239 aa)
gapAGlyceraldehyde-3-phosphate dehydrogenase A; Catalyzes the oxidative phosphorylation of glyceraldehyde 3- phosphate (G3P) to 1,3-bisphosphoglycerate (BPG) using the cofactor NAD. The first reaction step involves the formation of a hemiacetal intermediate between G3P and a cysteine residue, and this hemiacetal intermediate is then oxidized to a thioester, with concomitant reduction of NAD to NADH. The reduced NADH is then exchanged with the second NAD, and the thioester is attacked by a nucleophilic inorganic phosphate to produce BPG. (331 aa)
infBTranslation initiation factor IF-2; One of the essential components for the initiation of protein synthesis. May protect N-formylmethionyl-tRNA(fMet) from spontaneous hydrolysis. Promotes N-formylmethionyl-tRNA(fMet) binding to the 30S pre-initiation complex (PIC). Also involved in the hydrolysis of GTP during the formation of the 70S ribosomal complex. Upon addition of the 50S ribosomal subunit, IF-1, IF-2 and IF-3 are released leaving the mature 70S translation initiation complex. Belongs to the TRAFAC class translation factor GTPase superfamily. Classic translation factor GTPase fam [...] (890 aa)
mlaEABC transporter maintaining OM lipid asymmetry, inner membrane permease protein; Part of the ABC transporter complex MlaFEDB, which is involved in a phospholipid transport pathway that maintains lipid asymmetry in the outer membrane by retrograde trafficking of phospholipids from the outer membrane to the inner membrane. Probably responsible for the translocation of the substrate across the membrane. Belongs to the MlaE permease family. (260 aa)
mlaFABC transporter maintaining OM lipid asymmetry, ATP-binding protein; Part of the ABC transporter complex MlaFEDB, which is involved in a phospholipid transport pathway that maintains lipid asymmetry in the outer membrane by retrograde trafficking of phospholipids from the outer membrane to the inner membrane. Responsible for energy coupling to the transport system. (269 aa)
mdhMalate dehydrogenase, NAD(P)-binding; Catalyzes the reversible oxidation of malate to oxaloacetate. (312 aa)
rpsJ30S ribosomal subunit protein S10; Involved in the binding of tRNA to the ribosomes. In addition, in complex with NusB, is involved in the regulation of ribosomal RNA (rRNA) biosynthesis by transcriptional antitermination. S10 binds RNA non-specifically and increases the affinity of NusB for the boxA RNA sequence. S10 may constitute the critical antitermination component of the NusB-S10 complex. Belongs to the universal ribosomal protein uS10 family. (103 aa)
rpoBRNA polymerase, beta subunit; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. (1342 aa)
pgiGlucosephosphate isomerase; Protein involved in glycolysis and gluconeogenesis; Belongs to the GPI family. (549 aa)
lptFLipopolysaccharide export ABC permease; Part of the ABC transporter complex LptBFG involved in the translocation of lipopolysaccharide (LPS) from the inner membrane to the outer membrane. (366 aa)
