摘要：

Semiempirical (PM3) molecular orbital calculations on the mechanism of reoxidation of PQQ by triplet dioxygen suggest that the reaction can proceed purely by hydrogen-atom-transfer steps that are catalysed by the electrostatic effect of a coordinated calcium ion, rather than by an electron-transfer mechanism.
