  SMART: PQQ domain annotation
Beta-propeller repeat occurring in enzymes with pyrrolo-quinoline quinone (PQQ) as cofactor, in Ire1p-like Ser/Thr kinases, and in prokaryotic dehydrogenases.
The PQQ is located on the pseudo 8-fold rotation axis of the heavy subunit, in a funnel-shaped internal cavity, sandwiched between the indole ring of Trp237 and the two sulfur atoms of the Cys103-Cys104 vicinal disulfide.
The C5 atom of PQQ could be activated by electrophilic catalysis by a nearby argenine side-chain or by the calcium ion bound to PQQ.

  A New Vitamin Pyrroloquinoline Quinone (PQQ)
PQQ was discovered in 1979 from a bacterium, and afterward it was reported to be in common foods.
PQQ may also be considered a member of the vitamin B group[*2] by its molecular nature[*3] and function.
PQQ is mostly contained in common foods; comparatively in large quantities in natto (fermented soybeans), tea, papayas, and kiwi fruits (Table 1).

 New Vitamin, PQQ
The biochemical role for PQQ that qualifies it to be a vitamin is that of a redox cofactor in some enzymes and it must be obtained in the diet as the body apparently can’t produce it.
PQQ is a cofactor in PQQ-dependent dehydrogenase enzyme that is essential for the degradation of the amino acid lysine.
PQQ is a factor in quinoprotein enzymes that have been recognized as the third redox family following pyridine nucleotide- and flavin-dependent dehydrogenases.
