2-oxoisovalerate dehydrogenase (acylating)
class of enzymes
In enzymology, 2-oxoisovalerate dehydrogenase (acylating) (EC 1.2.1.25) is an enzyme that catalyzes the chemical reaction
The three substrates of this enzyme are α-ketoisovaleric acid, coenzyme A (CoA), and oxidised nicotinamide adenine dinucleotide (NAD+). Its products are isobutyryl-CoA, carbon dioxide, reduced NADH and a proton.
This enzyme belongs to the family of oxidoreductases, specifically those acting on the aldehyde or oxo group of donor with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is 3-methyl-2-oxobutanoate:NAD+ 2-oxidoreductase (CoA-methyl-propanoylating). Other names in common use include 2-oxoisovalerate dehydrogenase, and alpha-ketoisovalerate dehydrogenase. This enzyme participates in valine, leucine and isoleucine degradation.
This brief starts where responsible research should: with the source description of “2-oxoisovalerate dehydrogenase (acylating)” as class of enzymes. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as class of enzymes. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Jan 5, 2026. The linked authority identifier is Q3598023. None of the 0 selected statements returned an explicit reference.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
