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       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}.
