ID   2.8.1.15
DE   tRNA-5-methyluridine(54) 2-sulfurtransferase.
CA   5-methyluridine(54) in tRNA + [TtuB sulfur-carrier protein]-Gly-NH-CH2-
CA   C(O)SH + ATP + H2O = 5-methyl-2-thiouridine(54) in tRNA + [TtuB sulfur-
CA   carrier protein]-C-terminal Gly-Gly + AMP + diphosphate + 2 H(+).
CC   -!- The enzyme, found in thermophilic bacteria such as Thermus
CC       thermophilus and archaea such as Pyrococcus horikoshii, modifies the
CC       ribothymidine (5-methyluridine) residue at position 54 of tRNAs.
