KEGG   ENZYME: 1.2.5.2
Entry
EC 1.2.5.2                  Enzyme                                 
Name
aldehyde dehydrogenase (quinone);
aldehyde dehydrogenase (acceptor)
Class
Oxidoreductases;
Acting on the aldehyde or oxo group of donors;
With a quinone or similar compound as acceptor
Sysname
aldehyde:quinone oxidoreductase
Reaction(IUBMB)
an aldehyde + a quinone + H2O = a carboxylate + a quinol [RN:R10911]
Reaction(KEGG)
R10911 > R01019 R03535 R10912
Substrate
aldehyde [CPD:C00071];
quinone [CPD:C15602];
H2O [CPD:C00001]
Product
carboxylate [CPD:C00060];
quinol [CPD:C15603]
Comment
Wide specificity; acts on straight-chain aldehydes up to C10, aromatic aldehydes, glyoxylate and glyceraldehyde. The enzymes contains a PQQ cofactor and multiple hemes that deliver the electrons to the membrane quinone pool.
