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

Score
lppRRv2403c, (MTCY253.17), len: 251 aa. Probable lppR,conserved lipoprotein, with weak similarity with mycobacterial serine/threonine protein kinases e.g. AAK45563|MT1304 from Mycobacterium tuberculosis strain CDC1551 (626 aa), FASTA scores: opt: 186, E(): 0.00023,(24.4% identity in 238 aa overlap), and the C-terminal part of Q11053|Rv1266c|MTCY50.16|PKNH_MYCTU from Mycobacterium tuberculosis (626 aa), FASTA scores: opt: 185, E()= 0.00027, (24.35% identity in 238 aa overlap). Has signal peptide and appropriate positioned prokaryotic lipoprotein attachment site (PS00013). Could belong to th [...] (251 aa)    
Predicted Functional Partners:
lepA
Probable GTP-binding protein LepA (GTP-binding elongation factor); Required for accurate and efficient protein synthesis under certain stress conditions. May act as a fidelity factor of the translation reaction, by catalyzing a one-codon backward translocation of tRNAs on improperly translocated ribosomes. Back-translocation proceeds from a post-translocation (POST) complex to a pre- translocation (PRE) complex, thus giving elongation factor G a second chance to translocate the tRNAs correctly. Binds to ribosomes in a GTP- dependent manner.

lpqK
Rv0399c, (MTCY04D9.11c), len: 409 aa. Possible lpqK,conserved lipoprotein, showing some similarity to penicillin binding proteins and various peptidases e.g. DAC_STRSQ|P15555 d-alanyl-d-alanine carboxypeptidase protein (406 aa), FASTA scores: opt: 348, E(): 5.6e-16,(29.2% identity in 301 aa overlap). Also similar to other Mycobacterium tuberculosis PBPs and esterases. Has possible N-terminal signal sequence and appropriately positioned prokaryotic lipoprotein lipid attachment site (PS00013).
   
  
 0.658
lpqX
Probable lipoprotein LpqX; Rv1228, (MTCI61.11), len: 185 aa. Probable lipoprotein LpqX. Contains possible signal sequence and appropriately positioned PS00013 Prokaryotic membrane lipoprotein lipid attachment site.
   
  
 0.655
lpqB
Probable conserved lipoprotein LpqB; May modulate activity of the MtrAB system in controlling homeostasis of the cell wall and cell division (By similarity). Partially restores antibiotic resistance to M.smegmatis in which this gene has been disrupted.
   
  
 0.645
lpqI
Probable conserved lipoprotein LpqI; Plays a role in peptidoglycan recycling by cleaving the terminal beta-1,4-linked N-acetylglucosamine (GlcNAc) from peptidoglycan fragments. Acts as a regulator for GlcNAc-MurNAc levels by cleaving disaccharides and allowing the breakdown of MurNAc.
   
  
 0.644
lpqM
Rv0419, (MTCY22G10.16), len: 498 aa. Possible lpqM,lipoprotein peptidase; has potential N-terminal signal peptide and contains PS00013 Prokaryotic membrane lipoprotein lipid attachment site, PS00142 Neutral zinc metallopeptidases, zinc-binding region signature.

Rv2405
Conserved protein; Rv2405, (MTCY253.15c), len: 189 aa. Conserved protein, identical (but N-terminus longer 40 residues) to AAK46773|MT2477 hypothetical protein from Mycobacterium tuberculosis strain CDC1551. Also highly similar, but N-terminus longer 38 residues, to Q9RD03|SCCM1.41 hypothetical 17.4 KDA protein from Streptomyces coelicolor (154 aa), FASTA scores: opt: 451, E(): 2e-22, (48.7% identity in 154 aa overlap). Shows also similarity with hypothetical proteins from other species.

lpqT
Rv1016c, (MTCY10G2.33), len: 226 aa. Probable lpqT,conserved lipoprotein. Similar to several Mycobacterium tuberculosis hypothetical proteins e.g. Rv0040c|Y0H3_MYCTU|P71697 Proline rich 28 kDA antigen (310 aa), FASTA scores: opt: 329, E(): 2e-17, (32.3% identity in 229 aa overlap); Rv0583c.
