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

fgd2Putative F420-dependent glucose-6-phosphate dehydrogenase Fgd2; Catalyzes the coenzyme F420-dependent oxidation of hydroxymycolic acids (H-MAs) to ketomycolic acids (K-MAs), a lipid class making up the mycobacterial pseudo-outer membrane and over one- third of the dry weight of M.tuberculosis. Does not exhibit F420-dependent glucose-6-phosphate dehydrogenase (FGD) activity. (360 aa)    
Predicted Functional Partners:
ddn
Deazaflavin-dependent nitroreductase Ddn; 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 both benzoquinone and naphthoquinone analogs; since menaquinone is the sole quinone electron carrier in the respiratory chain in M.tuberculosis, the physiological electron acceptor for Fq [...]

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.
 
  
 0.888
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.
 
  
 0.878
fbiC
Probable F420 biosynthesis protein FbiC; Catalyzes the radical-mediated synthesis of 7,8-didemethyl-8- hydroxy-5-deazariboflavin (FO) from 5-amino-6-(D-ribitylamino)uracil and L-tyrosine; In the C-terminal section; belongs to the radical SAM superfamily. CofH family.
 
  
 0.849
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.

Rv0044c
Rv0044c, (MTCY21D4.07c), len: 264 aa. Possible oxidoreductase, highly similar to AAD32732.1|MmcI|AF127374| F420-dependent H4MPT reductase from Streptomyces lavendulae (264 aa). Also similar to Mycobacterium tuberculosis proteins e.g. Rv1855c, Rv0953c, Rv0791c, Rv0132c, etc.

Rv3178
Conserved 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 [...]

Rv3520c
Rv3520c, (MTV023.27c), len: 347 aa. Possible coenzyme F420-dependent oxidoreductase, equivalent to Q9CCV8|ML0348 possible coenzyme F420-dependent oxidoreductase from Mycobacterium leprae (350 aa), FASTA scores: opt: 2029, E(): 9.1e-120, (86.85% identity in 342 aa overlap). Similar to many coenzyme F420-dependent enzymes (and other proteins) e.g. Q9AD98|SCI52.11c putative ATP/GTP-binding protein from Streptomyces coelicolor (351 aa), FASTA scores: opt: 859, E(): 1.6e-46, (41.9% identity in 346 aa overlap); Q9X7Y1|SC6A5.35 putative oxidoreductase from Streptomyces coelicolor (341 aa), FA [...]

Also highly similar to MTCI5_28 from Mycobacterium tuberculosis.

Rv1261c
Conserved 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 [...]
