Comments [?]

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