In enzymology, a tRNA-uridine aminocarboxypropyltransferase (EC 2.5.1.25) is an enzyme that catalyzes the chemical reaction

S-adenosyl-L-methionine + tRNA uridine [math]\displaystyle{ \rightleftharpoons }[/math] 5'-methylthioadenosine + tRNA 3-(3-amino-3-carboxypropyl)-uridine

Thus, the two substrates of this enzyme are S-adenosyl-L-methionine and tRNA uridine, whereas its two products are 5'-methylthioadenosine and tRNA 3-(3-amino-3-carboxypropyl)-uridine.

This enzyme belongs to the family of transferases, specifically those transferring aryl or alkyl groups other than methyl groups. The systematic name of this enzyme class is S-adenosyl-L-methionine:tRNA-uridine 3-(3-amino-3-carboxypropyl)transferase.
