Comments:

AdoMet dependent methyltransferase. Pseudouridine in position 55 is important for efficient conversion of Psi54 to m1Psi54. This modification is located in the T-loop and is important for the tertiary structure of the tRNA molecule. Crystal structure of TrmY from M. jannaschii was solved at 1.4 and 1.55A resolution (see the entry for M. jannaschii TrmY).
