RL   J. Bacteriol. 192:4089-4102(2010).
CC   -!- FUNCTION: Has a broad substrate specificity and is able to
CC       catalyze the reduction of the malonic semialdehyde to 3-
CC       hydroxypropionic acid. YdfG is apparently supplementing RutE, the
CC       presumed malonic semialdehyde reductase involved in pyrimidine
CC       degradation since both are able to detoxify malonic semialdehyde.
CC       Also catalyzes the NADP-dependent oxidation of L-allo-threonine to
CC       L-2-amino-3-keto-butyrate, which is spontaneously decarboxylated
CC       into aminoacetone. Also acts on D-threonine, L-serine, D-serine,
CC       D-3-hydroxyisobutyrate, L-3-hydroxyisobutyrate, D-glycerate and L-
CC       glycerate. Although usually assayed in vitro as an oxidase, YdfG
CC       is presumed to be a reductase in vivo.
CC   -!- CATALYTIC ACTIVITY: 3-hydroxypropanoate + NADP(+) = 3-
CC       oxopropanoate + NADPH.
CC   -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC       Kinetic parameters:
CC         KM=0.54 mM for NADP(+) (at pH 9 and at 30 degrees Celsius);
CC         KM=40 mM for L-serine (at pH 9 and at 30 degrees Celsius);
CC         KM=69 mM for D-serine (at pH 9 and at 30 degrees Celsius);
CC         KM=60 mM for D-threonine (at pH 9 and at 30 degrees Celsius);
CC         KM=29 mM for L-allo-threonine (at pH 9 and at 30 degrees
CC         Celsius);
CC         KM=33 mM for L-glycerate (at pH 9 and at 30 degrees Celsius);
CC         KM=50 mM for D-glycerate (at pH 9 and at 30 degrees Celsius);
CC         KM=60 mM for L-3-hydroxyisobutyrate (at pH 9 and at 30 degrees
CC         Celsius);
CC         KM=61 mM for D-3-hydroxyisobutyrate (at pH 9 and at 30 degrees
CC         Celsius);
CC         Note=The highest catalytic efficiency was observed with L-allo-
CC         threonine;
CC       pH dependence:
CC         Optimum pH is about 8.5 for the oxidation of L-serine. Stable
CC         from pH 6.5 to 10.0;
CC       Temperature dependence:
CC         Still active after heating at 55 degrees Celsius for 80 minutes;
CC   -!- SUBUNIT: Homotetramer.
CC   -!- DISRUPTION PHENOTYPE: Cells lacking this gene grow poorly on
CC       pyrimidine nucleosides and bases as the sole source of nitrogen at
CC       room temperature indicating a probably accumulation of a toxic
CC       intermediate, the malonic semialdehyde.
CC   -!- MISCELLANEOUS: L-threonine, D-allo-threonine, DL-threo-3-phenyl-
CC       serine, malonate, DL-malate, citrate, isocitrate, DL-lactate, DL-
CC       tartrate, gluconate, glycerol and glycolate are inert as
CC       substrates.
CC   -!- SIMILARITY: Belongs to the short-chain dehydrogenases/reductases
CC       (SDR) family.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=X57947; Type=Frameshift; Positions=58;
