CC   -!- FUNCTION: Involved in the isomerization of 5-deoxy-glucuronate (5DG) to
CC       5-dehydro-2-deoxy-D-gluconate (DKG or 2-deoxy-5-keto-D-gluconate).
CC       {ECO:0000255|HAMAP-Rule:MF_01673}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=5-deoxy-D-glucuronate = 5-dehydro-2-deoxy-D-gluconate;
CC         Xref=Rhea:RHEA:25840, ChEBI:CHEBI:16669, ChEBI:CHEBI:58852;
CC         EC=5.3.1.30; Evidence={ECO:0000255|HAMAP-Rule:MF_01673};
CC   -!- PATHWAY: Polyol metabolism; myo-inositol degradation into acetyl-CoA;
CC       acetyl-CoA from myo-inositol: step 4/7. {ECO:0000255|HAMAP-
CC       Rule:MF_01673}.
CC   -!- SIMILARITY: Belongs to the isomerase IolB family. {ECO:0000255|HAMAP-
CC       Rule:MF_01673}.
