Enzyme Information

tRNA (pseudouridine(54)-N(1))-methyltransferase.
based on mapping to UniProt Q59034
S-adenosyl-L-methionine + pseudouridine(54) in tRNA = S-adenosyl-L- homocysteine + N(1)-methylpseudouridine(54) in tRNA.
-!- While this archaeal enzyme is specific for the 54 position and does not methylate pseudouridine at position 55, the presence of pseudouridine at position 55 is necessary for the efficient methylation of pseudouridine at position 54.
