Enzymes containing PQQ are called quinoproteins. PQQ and quinoproteins play a role in the redox metabolism and structural integrity of cells and tissues [PMID:2558842]. It was reported that aminoadipate semialdehyde dehydrogenase (AASDH) might also use PQQ as a cofactor, suggesting a possibility that PQQ is a vitamin in mammals. [PMID:12712191]. Believed to be a mammalian redox-cofactor vitamin (B group). Widely distributed in various foods such as vegetables and meat. Methoxatin is found in animal foods and green vegetables. Pyrroloquinoline quinone (PQQ), a redox co-factor, is an anionic, redox-cycling orthoquinone. Pyrroloquinoline quinone is isolated from cultures of methylotropic bacteria and tissues of mammals. Pyrroloquinoline quinone is an essential nutrient for mammals and is important for immune function[1][2].
