case <OC:Bacillota>
FUNCTION	Involved in the oxidation of myo-inositol (MI) and D-chiro- inositol (DCI) to 2-keto-myo-inositol (2KMI or 2-inosose) and 1-keto-D- chiro-inositol (1KDCI), respectively.
else
FUNCTION	Involved in the oxidation of myo-inositol (MI) to 2-keto-myo- inositol (2KMI or 2-inosose).
end case
