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

lepBRv2903c, (MTCY274.34c), len: 294 aa. Probable lepB,signal peptidase I (type II membrane protein) (see Braunstein & Belisle 2000), equivalent to O33021|LEP_MYCLE|ML1612|MLCB250.39 probable signal peptidase I from Mycobacterium leprae (289 aa), FASTA scores: opt: 1335, E(): 1.8e-77, (69.75% identity in 301 aa overlap). Also similar to many e.g. O86869|SIPX signal peptidase I from Streptomyces lividans (320 aa), FASTA scores: opt: 474, E(): 1e-22, (43.55% identity in 248 aa overlap); O69884|SIP1|SIPW putative signal peptidase I from Streptomyces coelicolor and Streptomyces lividans (259 a [...] (294 aa)    
Predicted Functional Partners:
rnhB
Probable ribonuclease HII protein RnhB (RNase HII); Endonuclease that specifically degrades the RNA of RNA-DNA hybrids.

Rv0519c
Rv0519c, (MTCY20G10.09c), len: 300 aa. Possible conserved membrane protein, with hydrophobic region near N-terminus. Could be a lipase. Similar to Rv0774c|MTCY369.19c|A70708 from Mycobacterium tuberculosis (312 aa), FASTA scores: opt: 1092, E(): 0, (57.9% identity in 299 aa overlap). Contains PS00120 Lipases, serine active site.

rplS
50S ribosomal protein L19 RplS; This protein is located at the 30S-50S ribosomal subunit interface and may play a role in the structure and function of the aminoacyl-tRNA binding site.
  
    0.846
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.
  
 
 0.843
secA1
Probable preprotein translocase SecA1 1 subunit; Part of the Sec protein translocase complex. Interacts with the SecYEG preprotein conducting channel. Has a central role in coupling the hydrolysis of ATP to the transfer of precursor proteins, serving as an ATP-driven molecular motor driving the stepwise translocation of polypeptide chains across the membrane (By similarity).
 
  
 0.822
Rv2901c
Conserved protein; Rv2901c, (MTCY274.32c), len: 101 aa. Conserved protein, very equivalent to O33023|ML1610|MLCB250.41 hypothetical 12.3 KDA protein from Mycobacterium leprae (101 aa), FASTA scores: opt: 658, E(): 2.6e-43, (99.0% identity in 101 aa overlap). Also highly similar to O69889|SC2E1.18 hypothetical protein from Streptomyces coelicolor and Streptomyces lividans (102 aa), FASTA scores: opt: 515, E(): 2.2e-32, (75.0% identity in 100 aa overlap). A core mycobacterial gene; conserved in mycobacterial strains (See Marmiesse et al., 2004).

Rv2253
Rv2253, (MTV022.03), len: 167 aa. Possible secreted protein; has potential N-terminal signal peptide. Predicted to be an outer membrane protein (See Song et al., 2008).
   
  
 0.809
secY
Probable preprotein translocase SecY; The central subunit of the protein translocation channel SecYEG. Consists of two halves formed by TMs 1-5 and 6-10. These two domains form a lateral gate at the front which open onto the bilayer between TMs 2 and 7, and are clamped together by SecE at the back. The channel is closed by both a pore ring composed of hydrophobic SecY resides and a short helix (helix 2A) on the extracellular side of the membrane which forms a plug. The plug probably moves laterally to allow the channel to open. The ring and the pore may move independently. Belongs to t [...]

secE1
Probable preprotein translocase SecE1; Essential subunit of the Sec protein translocation channel SecYEG. Clamps together the 2 halves of SecY. May contact the channel plug during translocation.

lspA
Probable lipoprotein signal peptidase LspA; This protein specifically catalyzes the removal of signal peptides from prolipoproteins; Belongs to the peptidase A8 family.
