text: Proper names of oxidoreductases are formed as "donor:acceptor oxidoreductase"; however, other names are much more common.
  * The common name is "donor dehydrogenase" when possible, such as glyceraldehyde-3-phosphate dehydrogenase for the second reaction above.
  * Common names are also sometimes formed as "acceptor reductase", such as NAD reductase.
  * "Donor oxidase" is a special case where O is the acceptor.
