CC -!- FUNCTION: Catalyzes the dehydration of inosose (2-keto-myo-inositol,
CC 2KMI or 2,4,6/3,5-pentahydroxycyclohexanone) to 3D-(3,5/4)-
CC trihydroxycyclohexane-1,2-dione (D-2,3-diketo-4-deoxy-epi-inositol).
CC {ECO:0000255|HAMAP-Rule:MF_01672}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=scyllo-inosose = 3D-3,5/4-trihydroxycyclohexane-1,2-dione +
CC H2O; Xref=Rhea:RHEA:14065, ChEBI:CHEBI:15377, ChEBI:CHEBI:17811,
CC ChEBI:CHEBI:28446; EC=4.2.1.44; Evidence={ECO:0000255|HAMAP-
CC Rule:MF_01672};
CC -!- COFACTOR:
CC Name=glutathione; Xref=ChEBI:CHEBI:57925;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01672};
CC -!- COFACTOR:
CC Name=Co(2+); Xref=ChEBI:CHEBI:48828;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01672};
CC Name=Mn(2+); Xref=ChEBI:CHEBI:29035;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01672};
CC -!- PATHWAY: Polyol metabolism; myo-inositol degradation into acetyl-CoA;
CC acetyl-CoA from myo-inositol: step 2/7. {ECO:0000255|HAMAP-
CC Rule:MF_01672}.
CC -!- SIMILARITY: Belongs to the IolE/MocC family. {ECO:0000255|HAMAP-
CC Rule:MF_01672}.
