STRINGSTRING
STRING protein interaction network
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

Rv3671cMembrane-associated serine protease; Required for M.tuberculosis resistance to oxidative stress in addition to its role in resistance to acid, which is essential for virulence. It protects M.tuberculosis against phagolysosomal concentrations of acid and maintains its intrabacterial pH when phagocytosed by IFN-gamma-activated macrophages. (397 aa)    
Predicted Functional Partners:
Rv3672c
Rv3672c, (MTV025.020c), len: 273 aa. Conserved hypothetical protein, equivalent to Q9CB94|ML2299 hypothetical protein from Mycobacterium leprae (266 aa) FASTA scores: opt: 1358, E(): 5.2e-75, (76.4% identity in 267 aa overlap). Also similar to others (generally in C-terminal end) e.g. Q9XA45|SCH17.02c hypothetical 26.5 KDA protein from Streptomyces coelicolor (247 aa) FASTA scores: opt: 524, E(): 1.3e-24, (42.65% identity in 251 aa overlap); Q9AB27|CC0407 mutt/NUDIX family protein from Caulobacter crescentus (216 aa), FASTA scores: opt: 285,E(): 3.2e-10, (36.2% identity in 174 aa overl [...]

mpa
Mycobacterial proteasome ATPase Mpa; ATPase which is responsible for recognizing, binding, unfolding and translocation of pupylated proteins into the bacterial 20S proteasome core particle. May be essential for opening the gate of the 20S proteasome via an interaction with its C-terminus, thereby allowing substrate entry and access to the site of proteolysis. Thus, the C-termini of the proteasomal ATPase may function like a 'key in a lock' to induce gate opening and therefore regulate proteolysis. Is required but not sufficient to confer resistance against the lethal effects of reactiv [...]

nth
Endonuclease III; DNA repair enzyme that has both DNA N-glycosylase activity and AP-lyase activity. The DNA N-glycosylase activity releases various damaged pyrimidines from DNA by cleaving the N-glycosidic bond, leaving an AP (apurinic/apyrimidinic) site. The AP-lyase activity cleaves the phosphodiester bond 3' to the AP site by a beta-elimination, leaving a 3'-terminal unsaturated sugar and a product with a terminal 5'- phosphate. Has a preference for oxidized pyrimidines, such as thymine glycol (prefers 5S isomers) 5,6-dihydrouracil:G, 5-hydroxyuracil:G, 5- hydroxycytosine:G and urea [...]

pepD
Rv0983, (MTV044.11), len: 464 aa. Probable pepD (alternate gene name: mtb32b), secreted or membrane serine protease (see citation below), equivalent (but longer 18 aa in N-terminus) to AL035500|MLCL373_17|T45448 probable serine proteinase from Mycobacterium leprae (452 aa), FASTA score: (74.2% identity in 466 aa overlap); and highly similar to others from Mycobacterium leprae. Also highly similar (except in N-terminus) to other proteases e.g. CAC01350.1|AL390975 putative protease from Streptomyces coelicolor (542 aa); NP_440705.1|NC_000911|HtrA serine protease from Synechocystis sp.

Also similar to mce-associated proteins from Mycobacterium tuberculosis e.g. Rv1363c, Rv0177, Rv1973, etc. Contains two 12 residue direct repeats at N-terminus. A core mycobacterial gene; conserved in mycobacterial strains (See Marmiesse et al.,2004).

prcB
Proteasome beta subunit PrcB; Component of the proteasome core, a large protease complex with broad specificity involved in protein degradation. The M.tuberculosis proteasome is able to cleave oligopeptides not only after hydrophobic but also after basic, acidic and small neutral residues. In complex with the ATPase Mpa, degrades protein targets conjugated to a prokaryotic ubiquitin-like protein (Pup). Among the identified substrates of the M.tuberculosis proteasome are the pupylated FabD, PanB and Mpa proteins. One function of the proteasome is to contribute to M.tuberculosis ability [...]
