CC   -!- FUNCTION: Catalyzes the decarboxylation of 3-keto-L-gulonate-6-P
CC       into L-xylulose-5-P. Is involved in the anaerobic L-ascorbate
CC       utilization (By similarity).
CC   -!- CATALYTIC ACTIVITY: 3-dehydro-L-gulonate 6-phosphate = L-xylulose
CC       5-phosphate + CO(2).
CC   -!- COFACTOR: Binds 1 magnesium ion per subunit (By similarity).
CC   -!- PATHWAY: Cofactor degradation; L-ascorbic acid degradation; D-
CC       xylulose 5-phosphate from L-ascorbic acid: step 2/4.
CC   -!- SUBUNIT: Homodimer (By similarity).
CC   -!- INDUCTION: Induced by L-ascorbate. Repressed by ulaR (By
CC       similarity).
CC   -!- SIMILARITY: Belongs to the HPS/KGPDC family. KGPDC subfamily.
