ID   2.8.1.15
DE   tRNA-5-methyluridine(54) 2-sulfurtransferase.
CA   ATP + [TtuB sulfur-carrier protein]-Gly-NH-CH(2)-C(O)SH +
CA   5-methyluracil(54) in tRNA + H(2)O = AMP + diphosphate + 5-methyl-2-
CA   thiouracil(54) in tRNA + [TtuB sulfur-carrier protein]-Gly-Gly.
CF   Zn(2+).
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.
