The Ca2+ complexes of PQQ-2,9-dimethyl ester and its iminoquinone derivative have been synthesised and the reactivity towards alcohols examined; the oxidising ability of the quinone is significantly enhanced by binding Ca2+ and NH3, both of which are essential for quinoprotein methanol dehydrogenase activation.
