CC -!- FUNCTION: Catalyzes the coenzyme F420-dependent oxidation of glucose 6-
CC phosphate (G6P) to 6-phosphogluconolactone. Appears to have a role in
CC resistance to oxidative stress, via its consumption of G6P that serves
CC as a source of reducing power to combat oxidative stress in
CC mycobacteria. {ECO:0000255|HAMAP-Rule:MF_02123}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=D-glucose 6-phosphate + H(+) + oxidized coenzyme F420-(gamma-
CC L-Glu)(n) = 6-phospho-D-glucono-1,5-lactone + reduced coenzyme F420-
CC (gamma-L-Glu)(n); Xref=Rhea:RHEA:27294, Rhea:RHEA-COMP:12939,
CC Rhea:RHEA-COMP:14378, ChEBI:CHEBI:15378, ChEBI:CHEBI:57955,
CC ChEBI:CHEBI:61548, ChEBI:CHEBI:133980, ChEBI:CHEBI:139511;
CC EC=1.1.98.2; Evidence={ECO:0000255|HAMAP-Rule:MF_02123};
CC -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_02123}.
CC -!- SIMILARITY: Belongs to the F420-dependent glucose-6-phosphate
CC dehydrogenase family. {ECO:0000255|HAMAP-Rule:MF_02123}.
