UniprotKB/SwissProt ID: Q9STS1 (Q9STS1)
Gene Name:
ALDH10A9
Organism: Arabidopsis thaliana (Mouse-ear cress)
Function: Dehydrogenase that catalyzes the oxidation of several aminoaldehydes (PubMed:21053011, PubMed:27725774, PubMed:32845293). Metabolizes and detoxifies aldehyde products of polyamine degradation to non-toxic amino acids (Probable). Catalyzes the oxidation of 4-aminobutanal and 3-aminopropanal to 4-aminobutanoate and beta-alanine, respectively (PubMed:21053011, PubMed:27725774, PubMed:32845293). Production of 4-aminobutinoate by ALDH10A9 may confer tolerance to salt stress (PubMed:27725774). Catalyzes the oxidation of 3-aminopropanal to beta-alanine (PubMed:21053011, PubMed:27725774, PubMed:32845293). Catalyzes the oxidation of 4-(trimethylamino)butanal and 4-guanidinobutanal to 4-trimethylammoniobutanoate and 4-guanidinobutanoate, respectively (PubMed:32845293). Involved in glycine betaine biosynthesis (PubMed:21053011, PubMed:26169197, PubMed:27725774, PubMed:32845293). Catalyzes with low efficiency the oxidation of betaine aldehyde to glycine betaine (PubMed:21053011, PubMed:27725774, PubMed:32845293)
