Deleted entry:  cellobiose dehydrogenase (quinone). Now known to be proteolytic product of EC, cellobiose dehydrogenase (acceptor)
[EC created 1983, deleted 2002]
Accepted name: D-2-hydroxyacid dehydrogenase (quinone)
Reaction: (R)-2-hydroxyacid + a quinone = 2-oxoacid + a quinol
Other name(s): (R)-2-hydroxy acid dehydrogenase; (R)-2-hydroxy-acid:(acceptor) 2-oxidoreductase; D-lactate dehydrogenase (ambiguous)
Systematic name: (R)-2-hydroxyacid:quinone oxidoreductase
Comments: The enzyme from mammalian kidney contains one mole of FAD per mole of enzyme.(R)-lactate, (R)-malate and meso-tartrate are good substrates. Ubiquinone-1 and the dye 2,6-dichloroindophenol can act as acceptors; NAD+ and NADP+ are not acceptors.

Accepted name: 1-butanol dehydrogenase (quinone)
Reaction: butan-1-ol + a quinone = butanal + a quinol
Other name(s): BOH
Systematic name: butan-1-ol:quinone oxidoreductase
Comments: This periplasmic quinoprotein alcohol dehydrogenase, characterized from the bacterium Thauera butanivorans, is involved in butane degradation. It contains a pyrroloquinoline quinone (PQQ) prosthetic group. cf. EC, 1-butanol dehydrogenase (cytochrome c).

Accepted name: D-lactate dehydrogenase (quinone)
Reaction: (R)-lactate + a quinone = pyruvate + a quinol
Other name(s): dld (gene name)
Systematic name: (R)-lactate:quinone 2-oxidoreductase
Comments: The enzyme is an FAD-dependent peripheral membrane dehydrogenase that participates in respiration. Electrons derived from D-lactate oxidation are transferred to the membrane soluble quinone pool.
