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

Rv1261cConserved 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. In vitro, catalyzes the reduction of menadione to menadiol; 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 li [...] (149 aa)

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.

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.
  
  
 0.824
fbiD
Conserved hypothetical alanine rich protein; Guanylyltransferase that catalyzes the activation of phosphoenolpyruvate (PEP) as enolpyruvoyl-2-diphospho-5'-guanosine, via the condensation of PEP with GTP. It is involved in the biosynthesis of coenzyme F420, a hydride carrier cofactor.
