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:
mazE2Possible antitoxin MazE2; Antitoxin component of a type II toxin-antitoxin (TA) system. (81 aa)
mazF3Toxin MazF3; Toxic component of a type II toxin-antitoxin (TA) system. Acts as an mRNA and 23S rRNA interferase, cleaving predominantly after the first 2 Us in the sequence 5'-UUCCU-3'; in 23S rRNA only cleaves once in the ribosomal A site in dissociated but not intact ribosomes. Cleavage of 23S rRNA inhibits protein translation; the 23S rRNA region cleaved is involved in tRNA-binding in the A site, 30S and 50S subunit interaction and ribosome recycling factor association. Upon expression in E.coli and M.smegmatis inhibits cell growth and colony formation. It dramatically increases per [...] (103 aa)
mazE3Possible antitoxin MazE3; Antitoxin component of a type II toxin-antitoxin (TA) system. Upon expression in E.coli and M.smegmatis neutralizes the effect of cognate toxin MazF3. Overexpression of MazE3 alone decreased persister cells formation in M.smegmatis upon challenge with gentamicin or kanamycin. (106 aa)
relEToxin RelE; Toxic component of a type II toxin-antitoxin (TA) system. Has RNase activity (By similarity). Overexpression in M.tuberculosis or M.smegmatis inhibits colony formation in a bacteriostatic rather than bacteriocidal fashion. Its toxic effect is neutralized by coexpression with cognate antitoxin RelB (shown only for M.smegmatis). (97 aa)
relAGuanosine-3',5'-bis(diphosphate) 3'-pyrophosphohydrolase; In eubacteria ppGpp (guanosine 3'-diphosphate 5-' diphosphate) is a mediator of the stringent response that coordinates a variety of cellular activities in response to changes in nutritional abundance. This enzyme catalyzes both the formation of pppGpp, which is then hydrolyzed to form ppGpp, as well as the hydrolysis of ppGpp. RelA is probably a key factor in the pathogenesis of M.tuberculosis as it regulates the intracellular concentrations of (p)ppGpp. (790 aa)
lexARepressor LexA; Represses a number of genes involved in the response to DNA damage (SOS response), including recA and lexA. Has been shown to bind to the 14 bp palindromic sequence 5'-CGAACNNNNGTTCG-3'. 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. (236 aa)
vapC21Possible toxin VapC21; Toxic component of a type II toxin-antitoxin (TA) system. An RNase (By similarity). Upon expression in M.smegmatis inhibits colony formation. Its toxic effect is neutralized by coexpression with cognate antitoxin VapB21; Belongs to the PINc/VapC protein family. (138 aa)
mazF9Toxin MazF9; Toxic component of a type II toxin-antitoxin (TA) system. Upon expression in E.coli and M.smegmatis inhibits cell growth and colony formation. Its toxic effect is neutralized by coexpression with cognate antitoxin MazE9. Acts as an mRNA interferase, specifically cleaving between U and C in UAC sequences. May cleave its cognate antitoxin's gene. In E.coli expression with non- cognate antitoxins VapB27 and VapB40 partially neutralizes the toxin. Belongs to the PemK/MazF family. (118 aa)
relFAntitoxin RelF; Antitoxin component of a type II toxin-antitoxin (TA) system. Upon expression in M.smegmatis neutralizes the effect of toxin RelE2. (93 aa)
pfkAProbable 6-phosphofructokinase PfkA (phosphohexokinase) (phosphofructokinase); Catalyzes the phosphorylation of D-fructose 6-phosphate to fructose 1,6-bisphosphate by ATP, the first committing step of glycolysis; Belongs to the phosphofructokinase type A (PFKA) family. Mixed-substrate PFK group III subfamily. (343 aa)
mazF1Possible toxin MazF1; Toxic component of a type II toxin-antitoxin (TA) system, its cognate antitoxin is MazE1 (Probable). Probably an endoribonuclease (By similarity); Belongs to the PemK/MazF family. (93 aa)
vapB25Rv0277A, len: 85 aa. Possible vapB25, antitoxin,part of toxin-antitoxin (TA) operon with Rv0277c, see Arcus et al. 2005. Has in-frame stop codon so may not be expressed. Very similar to others in Mycobacterium tuberculosis e.g. Rv0748 (85 aa). Fasta score E(): 4e-24; 88.2% identity in 85 aa overlap. (85 aa)
vapB24Possible antitoxin VapB24; Possibly the antitoxin component of a type II toxin-antitoxin (TA) system. Its cognate toxin is VapC24. (77 aa)
relJAntitoxin RelJ; Antitoxin component of a type II toxin-antitoxin (TA) system. A probable antitoxin for the putative mRNA interferase RelK. Upon expression in E.coli but not in M.smegmatis this protein neutralizes E.coli YoeB. (91 aa)
ccdARv0527, (MTCY25D10.06), len: 259 aa. Possible ccdA,cytochrome C-type biogenesis protein, integral membrane protein, equivalent to Q49810|B2168_C1_192|S72890 hypothetical protein from Mycobacterium leprae (262 aa),FASTA scores: opt: 1341, E(): 0, (79.0% identity in 262 aa overlap). Also highly similar to others e.g. CAC08380.1 (253 aa); CCDA_BACSU|P45706 cytochrome C-type biogenesis protein from Bacillus subtilis (235 aa), FASTA scores: opt: 307, E(): 7.4e-13, (30.4% identity in 237 aa overlap); etc. Seems to belong to the DSBD subfamily. Note that previously known as ccsA. (259 aa)
mazE1Possible antitoxin MazE1; Antitoxin component of a type II toxin-antitoxin (TA) system. (57 aa)
vapB26Possible antitoxin VapB26; Antitoxin component of a type II toxin-antitoxin (TA) system. Upon expression in M.smegmatis neutralizes the effect of cognate toxin VapC26. (71 aa)
vapC26Possible toxin VapC26. Contains PIN domain; Toxic component of a type II toxin-antitoxin (TA) system. An RNase (By similarity). Upon expression in M.smegmatis inhibits colony formation. Its toxic effect is neutralized by coexpression with cognate antitoxin VapB26.; Belongs to the PINc/VapC protein family. (135 aa)
