Protein
tRNA-cytidine(32) 2-sulfurtransferase 2
Organism
Francisella tularensis subsp. holarctica (strain FTNF002-00 / FTA)
Function
Catalyzes the ATP-dependent 2-thiolation of cytidine in position 32 of tRNA, to form 2-thiocytidine (s(2)C32). The sulfur atoms are provided by the cysteine/cysteine desulfurase (IscS) system.
Similarity
Belongs to the TtcA family.
