Effect of pyrroloquinoline quinone on skin aging in Bmi-1 KO mice and underlying mechanisms.
PLoS ONETo investigate the effect of pyrroloquinoline quinone (PQQ) on skin aging in the Bmi-1 KO mice and its underlying mechanisms, we administered a normal diet to both Wild type mice (WT) and Bmi-1 KO mice, while supplementing the diet of Bmi-1 KO mice with ...

Pyrroloquinoline quinone (PQQ) is the organic cofactor in soybean lipoxygenase-1
, 1988 Treatment of soybean lipoxygenase-1 (SLO) with phenylhydrazine (PH) induced inactivation and a maximum (350 nm) in the absorption spectrum of the enzyme. To detach the product having this absorption maximum, proteolysis was required. The product appeared

Characteristic Reaction Mode of Cofactor PQQ toward Nucleophiles
, 1997 [Abstract] The characteristic reaction mode of coenzyme PQQ toward nucleophiles such as alcohols, amines, and hydrazines are surveyed. The selectivity of addition position of nucleophiles to the carbonyl group of PQQ was affected by reaction conditions ...

The Effects of Illumination onthe Oxidation Reactions of PQQ. Lousine Boyadzhyan & Alicia McCarthy
, 1999 PQQ, formally known as 2,7,9-tricarboxy-1H-pyrrolo [2,3-f] quinoline-4,5-dione, exists as an enzyme cofactor in bacterial methanol and glucose dehydrogenases. Since its discovery in 1979, the reactivity of PQQ has attracted much research attention.
