CC -!- FUNCTION: Involved in the cleavage of the C1-C2 bond of 3D-(3,5/4)-
CC trihydroxycyclohexane-1,2-dione (THcHDO) to yield 5-deoxy-glucuronate
CC (5DG). {ECO:0000255|HAMAP-Rule:MF_01669}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=3D-3,5/4-trihydroxycyclohexane-1,2-dione + H2O = 5-deoxy-D-
CC glucuronate + H(+); Xref=Rhea:RHEA:25836, ChEBI:CHEBI:15377,
CC ChEBI:CHEBI:15378, ChEBI:CHEBI:28446, ChEBI:CHEBI:58852; EC=3.7.1.22;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01669};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01669};
CC Note=Binds 1 Mg(2+) ion per subunit. {ECO:0000255|HAMAP-Rule:MF_01669};
CC -!- COFACTOR:
CC Name=thiamine diphosphate; Xref=ChEBI:CHEBI:58937;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01669};
CC Note=Binds 1 thiamine pyrophosphate per subunit. {ECO:0000255|HAMAP-
CC Rule:MF_01669};
CC -!- PATHWAY: Polyol metabolism; myo-inositol degradation into acetyl-CoA;
CC acetyl-CoA from myo-inositol: step 3/7. {ECO:0000255|HAMAP-
CC Rule:MF_01669}.
CC -!- SIMILARITY: Belongs to the TPP enzyme family. {ECO:0000255|HAMAP-
CC Rule:MF_01669}.
