Pyrroloquinoline quinone (PQQ), also called methoxatin, is a redox cofactor and antioxidant. Produced by bacteria, it is found in soil and foods such as kiwifruit, as well as human breast milk. Enzymes using PQQ as a redox cofactor are called quinoproteins and play a variety of redox roles. Quinoprotein glucose dehydrogenase is used as a glucose sensor in bacteria. PQQ stimulates growth in bacteria. Eukaryote targets, including mammalian lactate dehydrogenase, are of more interest to health. It is suggested that PQQ taken as a dietary supplement could promote mitochondrial biogenesis via this pathway as well as PGC-1α.
Carbohydrate dehydrogenases are a group of dehydrogenase enzymes that occur in many organisms and facilitate the conversion from a carbohydrate to an aldehyde, lactone, or ketose.

Flavin reductase a class of enzymes. There are a variety of flavin reductases, which bind free flavins and through hydrogen bonding, catalyze the reduction of these molecules to a reduced flavin. Riboflavin, or vitamin B, and flavin mononucleotide are two of the most well known flavins in the body and are used in a variety of processes which include metabolism of fat and ketones and the reduction of methemoglobin in erythrocytes. Flavin reductases are similar and often confused for ferric reductases because of their similar catalytic mechanism and structures.
