tRNA pseudouridine(55) synthase.
based on mapping to UniProt Q9WZW0
tRNA uridine(55) = tRNA pseudouridine(55).
-!- Pseudourine synthase TruB from Escherichia coli specifically modifies uridine(55) in tRNA molecules. -!- The bifunctional archaeal enzyme also catalyzes the pseudouridylation of uridine(54). -!- It is not known whether the enzyme from Escherichia coli can also act on position 54 in vitro, since this position is occupied in E.coli tRNAs by thymine.
