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}.
