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

C-terminal part highly similar to O33118|MLCB637.27c hypothetical 14.7 KDA protein (probable pseudogene product) from Mycobacterium leprae (134 aa), FASTA scores: opt: 483,E(): 2.7e-21, (60.9% identity in 138 aa overlap). Also similar to various transporters e.g. Q9I5C8|PA0811 probable MFS transporter from Pseudomonas aeruginosa (415 aa), FASTA scores: opt: 289, E(): 1.3e-09, (26.05% identity in 399 aa overlap); O30210|AF0 [...] (445 aa)    
Predicted Functional Partners:
lipC
Probable esterase LipC; Esterase that can hydrolyze short-chain esters with the carbon chain containing 2 to 10 carbon atoms. Does not have lipase activity. Is highly immunogenic and elicits strong humoral immune responses in both HIV-negative (HIV-) and HIV-positive (HIV+) tuberculosis (TB) patients. Also elicits proinflammatory cytokine and chemokine responses from macrophages and pulmonary epithelial cells. May participate in the progression of active tuberculosis both by contributing to the utilization of lipid substrates for bacterial growth and replication, and by modulating immu [...]

Rv2957
Possible glycosyl transferase; Involved in glycosylation steps downstream of mono-O-methyl- glycosyl-p-hydroxybenzoic acid derivative (p-HBAD I) and 2-O-methyl- rhamnosyl-phenolphthiocerol dimycocerosate (mycoside B) during the p- hydroxybenzoic acid derivatives (p-HBAD) and glycosylated phenolphthiocerol dimycocerosates (PGL) biosynthesis. Belongs to the glycosyltransferase 2 family.

gltS
Glutamyl-tRNA synthetase GltS (glutamate--tRNA ligase) (glutamyl-tRNA synthase) (GLURS); Catalyzes the attachment of glutamate to tRNA(Glu) in a two- step reaction: glutamate is first activated by ATP to form Glu-AMP and then transferred to the acceptor end of tRNA(Glu).
