Biochemistry: is pyrroloquinoline quinone a vitamin?
Nature, 2005The announcement by Kasahara and Kato of pyrroloquinoline quinone (PQQ) as a 'new' vitamin has received considerable attention. We have since attempted to reproduce the findings on which their conclusion is based, namely that defects in lysine metabolism occur in PQQ-deprived rodents.

Potential physiological importance of pyrroloquinoline quinone.
Alternative medicine review : a journal of clinical therapeutic, 2009Pyrroloquinoline quinone (PQQ) is a novel biofactor for which a proposition can be made for physiological importance. PQQ was first recognized as an enzyme cofactor in bacteria. It has recently been tentatively identified as a component of interstellar dust. Thus, PQQ may have been present throughout early biological conception and evolution.

Brain glutamate decarboxylase and pyrroloquinoline quinone.
BioFactors (Oxford, England), 1992Porcine brain glutamate decarboxylase was examined for the presence of covalently bound pyrroloquinoline quinone (PQQ). HPLC analysis of pure glutamate decarboxylase subjected to the hexanol extraction procedure gave negative results when monitored at 320 nm, the maximum of absorbance of 4-hydroxy-5-hexoxy-PQQ. Resolved glutamate decarboxylase exhibits
