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:
mmsAMethylmalonate-semialdehyde dehydrogenase; Identified by similarity to GB:AAA99190.1; match to protein family HMM PF00171; match to protein family HMM TIGR01722. (506 aa)
sigHRNA polymerase sigma-70 factor, family protein; 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 an anti-sigma factor until released. This sigma factor is involved in heat shock and oxidative stress responses. (219 aa)
nuoNNADH-quinone oxidoreductase, N subunit; 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 a menaquinone. 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; Belongs to the complex I subunit 2 family. (521 aa)
nuoBNADH-quinone oxidoreductase, B subunit; 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 a menaquinone. 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. (184 aa)
mutMformamidopyrimidine-DNA glycosylase; Involved in base excision repair of DNA damaged by oxidation or by mutagenic agents. Acts as DNA glycosylase that recognizes and removes damaged bases. Acts on oxidized purines, such as 7,8-dihydro-8- oxoguanine (8-oxoG) when paired with C, G or T. Has AP (apurinic/apyrimidinic) lyase activity and introduces nicks in the DNA strand. Cleaves the DNA backbone by beta-delta elimination to generate a single-strand break at the site of the removed base with both 3'- and 5'-phosphates; Belongs to the FPG family. (285 aa)
mmsA-2Methylmalonate-semialdehyde dehydrogenase; Identified by match to protein family HMM PF00171; match to protein family HMM TIGR01722. (497 aa)
recAProtein RecA; Required for homologous recombination (HR) and the bypass of mutagenic DNA lesions (double strand breaks, DSB) by the SOS response. 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. Numerous X-ray crystals have been resolved under different conditions which indicate the flexibility of the protein, essential to its function. Gln-196 contributes to this plasticity by acting as a switch residue, which transmits the ef [...] (349 aa)
recXRegulatory protein RecX; Modulates RecA activity; Belongs to the RecX family. (188 aa)
lexALexA repressor; Represses a number of genes involved in the response to DNA damage (SOS response), including recA and lexA. 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. (243 aa)
katGCatalase/peroxidase HPI; Bifunctional enzyme with both catalase and broad-spectrum peroxidase activity. May play a role in the intracellular survival of mycobacteria. (748 aa)
katG-2Catalase/peroxidase HPI; Bifunctional enzyme with both catalase and broad-spectrum peroxidase activity; Belongs to the peroxidase family. Peroxidase/catalase subfamily. (688 aa)
ligD-2DNA ligase; With Ku forms a non-homologous end joining (NHEJ) repair enzyme which repairs blunt-end and 5'-overhang DNA double strand breaks (DSB) with about 50% fidelity, and DSB with non-complementary 3' ends. Plays a partial role in NHEJ during 3'-overhang repair. NHEJ repairs DSB with blunt ends and 5' overhangs with a high level of nucleotide insertion/deletion, without a need for microhomology. Acts as a DNA ligase on singly nicked dsDNA, as a DNA-directed DNA polymerase on 5' overhangs, and adds non-templated nucleotides to 3' overhangs (terminal transferase). Fills in gaps in d [...] (755 aa)
ligDDNA polymerase LigD, polymerase domain; Identified by match to protein family HMM TIGR02778. (350 aa)
katG-3Catalase/peroxidase HPI; Bifunctional enzyme with both catalase and broad-spectrum peroxidase activity. May play a role in the intracellular survival of mycobacteria. (739 aa)
bfrBFerritin family protein; Iron-storage protein that displays ferroxidase activity, catalyzing the oxidation of Fe(2+) ions into Fe(3+) ions, that can then be deposited as a ferric-oxide mineral core within the central cavity of the protein complex. (181 aa)
eccE3Conserved hypothetical protein; Part of the ESX-3 specialized secretion system, which is required for siderophore-mediated iron acquisition and for the secretion of EsxH and EsxG. (309 aa)
eccB1Conserved hypothetical protein; An ATPase (shown for residues 72-479). Part of the ESX-1 / type VII specialized secretion system (T7SS), which exports several proteins including EsxA and EsxB.

eccA3ATPase, AAA family protein; Part of the ESX-3 specialized secretion system, which is required for siderophore-mediated iron acquisition and for the secretion of EsxH and EsxG. EccA3 exhibits ATPase activity and may provide energy for the export of ESX-3 substrates (By similarity). (589 aa)
