This domain can be found in the C terminus of threonylcarbamoyl-AMP synthases, including Sua5 from Saccharomyces cerevisiae and YwlC from Bacillus subtilis. Threonylcarbamoyl-AMP synthase is required for the formation of a threonylcarbamoyl group on adenosine at position 37 (t6A37) in tRNAs that read codons beginning with adenine [1,2]. This domain adopts the Rossmann fold and may be involved in GTP and/or tRNA binding based on structural similarity with both GTP and tRNA binding proteins [3].	Domain
A, B, C, D	PF01300	Telomere recombination (Sua5_yciO_yrdC)	Telomere recombination	This domain has been shown to bind preferentially to dsRNA [1]. The domain is found in SUA5 Swiss:P32579 as well as HypF and YrdC Swiss:P45748. It has also been shown to be required for telomere recombniation in yeast.	Domain
