ATP-binding protein
This family of proteins belongs to the PP-loop superfamily [1]. [1]. 7731953. A P-loop-like motif in a widespread ATP pyrophosphatase domain: implications for the evolution of sequence motifs and enzyme activity. Bork P, Koonin EV;. Proteins 1994;20:347-355. (from Pfam)
tRNA 2-thiocytidine biosynthesis protein TtcA
tRNA 2-thiocytidine biosynthesis protein TtcA 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
tRNA 2-thiocytidine(32) synthetase TtcA
YdaO; catalyzes the thiolation of cytosine 32 in specific tRNAs
