Enzyme Information

5.4.99.12
tRNA pseudouridine(38-40) synthase.
based on mapping to UniProt Q9Y606
tRNA uridine(38-40) = tRNA pseudouridine(38-40).
-!- The uridylate residues at positions 38, 39 and 40 of nearly all tRNAs are isomerized to pseudouridine. -!- TruA specifically modifies uridines at positions 38, 39, and/or 40 in the anticodon stem loop of tRNAs with highly divergent sequences and structures.
