IUBMB Comments
Pseudouridine synthase TruB from Escherichia coli specifically modifies uridine55 in tRNA molecules . The bifunctional archaeal enzyme also catalyses the pseudouridylation of uridine54 . It is not known whether the enzyme from Escherichia coli can also act on position 54 in vitro, since this position is occupied in Escherichia coli tRNAs by thymine.
