tRNA threonylcarbamoyladenosine dehydratase

UniProtKB accession:  Q46927

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Catalyzes the ATP-dependent dehydration of threonylcarbamoyladenosine at position 37 (t(6)A37) to form cyclic t(6)A37 (ct(6)A37) in tRNAs that read codons beginning with adenine. TcdA is also part of a sulfur transfer pathway; is able to accept sulfur from CsdA directly in vitro, but CsdE might act as the sulfur donor in vivo.
