CC -!- FUNCTION: Dual-specificity methyltransferase that catalyzes the
CC formation of 5-methyluridine at position 54 (m5U54) in all tRNAs, and
CC that of position 341 (m5U341) in tmRNA (transfer-mRNA).
CC {ECO:0000255|HAMAP-Rule:MF_01011}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=S-adenosyl-L-methionine + uridine(54) in tRNA = 5-
CC methyluridine(54) in tRNA + H(+) + S-adenosyl-L-homocysteine;
