RT "Complete sequence of Chromosome1 of Ralstonia eutropha JMP134.";
RL Submitted (AUG-2005) to the EMBL/GenBank/DDBJ databases.
CC -!- FUNCTION: Catalyzes oxidation of L-threonate to 2-oxo-tetronate. Can
CC use either NAD(+) or NADP(+) as cosubstrate, with a preference for
CC NAD(+). {ECO:0000256|ARBA:ARBA00037062}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=L-threonate + NAD(+) = 2-dehydro-L-erythronate + H(+) + NADH;
CC Xref=Rhea:RHEA:52548, ChEBI:CHEBI:15378, ChEBI:CHEBI:57540,
CC ChEBI:CHEBI:57561, ChEBI:CHEBI:57945, ChEBI:CHEBI:136669;
CC EC=1.1.1.411; Evidence={ECO:0000256|ARBA:ARBA00036958};
CC -!- SIMILARITY: Belongs to the HIBADH-related family. L-threonate
CC dehydrogenase subfamily. {ECO:0000256|ARBA:ARBA00037979}.
