EC 1.2.99.6 Details

show Brenda entry

EC number

1.2.99.6

Accepted name

carboxylate reductase

Reaction

an aldehyde + acceptor + H₂O = a carboxylate + reduced acceptor

Other name(s)

aldehyde:(acceptor) oxidoreductase

Systematic name

aldehyde:acceptor oxidoreductase

CAS registry number

125008-36-8

Comment

A tungsten protein. Methyl viologen can act as acceptor. In the reverse direction, non-activated acids are reduced by reduced viologens to aldehydes, but not to the corresponding alcohols.

History

created 1992
