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

Rv3668cPossible protease; Rv3668c, (MTV025.016c), len: 232 aa. Possible protease (and more specifically a putative alkaline serine protease, equivalent to Q9CB98|ML2295 hypothetical protein from Mycobacterium leprae (234 aa), FASTA scores: opt: 1249, E(): 7.4e-66, (77.5% identity in 231 aa overlap). Also similar at C-terminal end with many proteases e.g. O86984 alkaline serine protease precursor from Thermomonospora fusca (368 aa), FASTA scores: opt: 190,E(): 0.00056, (28.9% identity in 173 aa overlap); Q55353|SAPII alkaline serine protease II from Streptomyces sp (382 aa), FASTA scores: opt: [...] (232 aa)    
Predicted Functional Partners:
TB22.2
Probable conserved secreted protein TB22.2; Hydrolyzes ester substrates carbon chain lengths ranging from C2 to C14. In vitro, acetate (C2), butyrate (C4) and caprylate (C6) are hydrolyzed with high efficiency. Has lower activity against laurate (C12), myristate (C14) and caproate (C8), and weak activity against palmitate (C16).

Rv3802c
Rv3802c, (MTV026.07c), len: 336 aa. Probable conserved membrane protein, with a N-terminal signal sequence followed by Pro-rich region. Equivalent to Q9CDB3|ML0099 hypothetical protein from Mycobacterium leprae (336 aa) FASTA scores: opt: 1759, E(): 1.1e-85,(75.5% identity in 335 aa overlap). A core mycobacterial gene; conserved in mycobacterial strains (See Marmiesse et al., 2004). Predicted to be an outer membrane protein (See Song et al., 2008).

aftC
Possible arabinofuranosyltransferase AftC; Involved in the biosynthesis of the arabinogalactan (AG) region of the mycolylarabinogalactan-peptidoglycan (mAGP) complex, an essential component of the mycobacterial cell wall.
