3-keto-L-gulonate-6-phosphate decarboxylase SgbH
3-keto-L-gulonate-6-phosphate decarboxylase UlaD
Ascorbic acid + HPr - phosphorylated → HPr + L-ascorbate 6-phosphate
Ascorbate-specific PTS system EIIB component
Ascorbate-specific PTS system EIIA component
Dual-specificity RNA pseudouridine synthase RluF
2 Ascorbic acid + Hydrogen Ion + Hydrogen peroxide → Ascorbic acid + Dehydroascorbic acid + 2 Water
dehydroascorbate (bicyclic form) → 2,3-Diketo-L-gulonate + Hydrogen Ion
Dehydroascorbic acid + Water → dehydroascorbate (bicyclic form)
Putative L-ribulose-5-phosphate 3-epimerase SgbU
3-keto-L-gulonate 6-phosphate + Hydrogen Ion → Carbon dioxide + L-xylulose -5-phosphate
L-ascorbate 6-phosphate + Water → 3-keto-L-gulonate 6-phosphate
3-Dehydro-L-gulonate + Adenosine triphosphate → 3-keto-L-gulonate 6-phosphate + Adenosine diphosphate + Hydrogen Ion
2,3-Diketo-L-gulonate + Hydrogen Ion + NADH → 3-Dehydro-L-gulonate + NAD
L-xylulose -5-phosphate → L-ribulose 5-phosphate
L-ribulose 5-phosphate → Xylulose 5-phosphate
