Hypothetical protein; Rv0789c, (MTCY369.33c), len: 199 aa. Hypothetical unknown protein.

Possible monooxygenase; Putative monooygenase that might be involved in antibiotic biosynthesis, or may act as reactive oxygen species scavenger that could help in evading host defenses.

Rv3072c, (MTCY22D7.09), len: 174 aa. Hypothetical protein, similar in part to O87779 hypothetical 18.1 KDA protein (fragment) from Mycobacterium paratuberculosis (166 aa), FASTA scores: opt: 238, E(): 2.5e-08, (42.6% identity in 108 aa overlap); Q9AH10 putative F420-dependent dehydrogenase from Rhodococcus erythropolis (295 aa), FASTA scores: opt: 228, E(): 1.7e-07, (34.25% identity in 111 aa overlap); P71557|Y953_MYCTU|Rv0953c|MTCY10D7.21 possible oxidoreductase from Mycobacterium tuberculosis strain H37Rv (304 aa), FASTA scores: opt: 208, E(): 3.2e-06, (38.9% identity in 108 aa overl [...]

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.

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.

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 [...]

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 [...]

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 [...]
