Organism

Arabidopsis thaliana (Mouse-ear cress)

Taxonomic identifier

3702 [NCBI]

Taxonomic lineage

Eukaryota › Viridiplantae › Streptophyta › Embryophyta › Tracheophyta › Spermatophyta › Magnoliophyta › eudicotyledons › core eudicotyledons › rosids › malvids › Brassicales › Brassicaceae › Camelineae › Arabidopsis

Protein attributes

Sequence length	607 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at transcript level

General annotation (Comments)

Catalytic activity	2-methyl-3-oxopropanoate + CoA + H2O + NAD+ = propanoyl-CoA + HCO3- + NADH.
Subcellular location	Mitochondrion Potential.
Sequence similarities	Belongs to the aldehyde dehydrogenase family.
Caution	In contrast to other members of the family, the conserved Glu residue in position 94 is replaced by an Arg. Its activity is therefore unsure.
