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

Rv3178Conserved hypothetical protein; Involved in a F420-dependent anti-oxidant mechanism that protects M.tuberculosis against oxidative stress and bactericidal agents. Catalyzes the F420H(2)-dependent two-electron reduction of quinones to dihydroquinones, thereby preventing the formation of cytotoxic semiquinones obtained by the one-electron reduction pathway. Since menaquinone is the sole quinone electron carrier in the respiratory chain in M.tuberculosis, the physiological electron acceptor for Fqr-mediated F420H(2) oxidation is therefore likely to be the endogenous menaquinone found in t [...] (119 aa)    
Predicted Functional Partners:
fgd1
F420-dependent glucose-6-phosphate dehydrogenase Fgd1; Catalyzes the coenzyme F420-dependent oxidation of glucose 6- phosphate to 6-phosphogluconolactone. Appears to have a role in resistance to oxidative stress, via its consumption of G6P that serves as a source of reducing power to combat oxidative stress in mycobacteria. More precisely, is likely involved in a F420-dependent anti-oxidant mechanism that protects M.tuberculosis against oxidative stress and bactericidal agents.

fbiA
Probable F420 biosynthesis protein FbiA; Catalyzes the transfer of the phosphoenolpyruvate moiety from enoylpyruvoyl-2-diphospho-5'-guanosine (EPPG) to 7,8-didemethyl-8- hydroxy-5-deazariboflavin (FO) with the formation of dehydro coenzyme F420-0 and GMP; Belongs to the CofD family.

fbiB
Probable F420 biosynthesis protein FbiB; Bifunctional enzyme that catalyzes the GTP-dependent successive addition of multiple gamma-linked L-glutamates to the L- lactyl phosphodiester of 7,8-didemethyl-8-hydroxy-5-deazariboflavin (F420-0) to form polyglutamated F420 derivatives, and the FMNH2- dependent reduction of dehydro-F420-0 to form F420-0.

Rv1155
F420H(2)-dependent reductase Rv1155; F420H(2)-dependent reductase able to catalyze the reduction of biliverdin-IXalpha to bilirubin-IXalpha in vitro. However, kinetic parameters show that it is less efficient than the biliverdin reductase Rv2074 and suggest biliverdin-IXalpha is unlikely to be the native substrate of Rv1155, which probably catalyzes the reduction of an alternative molecule in vivo. Binds coenzyme F420, but does not bind FMN or other flavins. Cannot use pyridoxine 5'-phosphate, pyridoxamine 5'-phosphate, pyridoxal 5'- phosphate (PLP), the anti-tuberculosis drug PA-824 o [...]
