FunFam 24: Pyruvate decarboxylase isozyme

There are 5 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
Branched-chain-2-oxoacid decarboxylase. [EC: 4.1.1.72]
(3S)-3-methyl-2-oxopentanoate = 2-methylbutanal + CO(2).
  • Acts on a number of 2-oxo acids, with a high affinity toward branched-chain substrates.
  • The aldehyde formed may be enzyme-bound, and may be an intermediate in the bacterial system for biosynthesis of branched-chain fatty acids.

Indolepyruvate decarboxylase. [EC: 4.1.1.74]
3-(indol-3-yl)pyruvate = 2-(indol-3-yl)acetaldehyde + CO(2).
  • More specific than EC 4.1.1.1.

4-hydroxyphenylpyruvate decarboxylase. [EC: 4.1.1.80]
4-hydroxyphenylpyruvate = 4-hydroxyphenylacetaldehyde + CO(2).
  • Reacts with dopamine to give the benzylisoquinoline alkaloid skeleton.

Pyruvate decarboxylase. [EC: 4.1.1.1]
A 2-oxo acid = an aldehyde + CO(2).
  • Also catalyzes acyloin formation.
