A	PF01171	PP-loop domain (ATP_bind_3)	PP-loop domain	The structure of tRNA(Ile)-lysidine synthetase consists of an N-terminal dinucleotide-binding fold domain (NTD), and a C-terminal globular domain (CTD). The structure of the NTD closely resembles that of a P-loop "N-type" ATP pyrophosphatase [2]. The ...	The structure of tRNA(Ile)-lysidine synthetase consists of an N-terminal dinucleotide-binding fold domain (NTD), and a C-terminal globular domain (CTD). The structure of the NTD closely resembles that of a P-loop "N-type" ATP pyrophosphatase [2]. These proteins belong to the PP-loop superfamily [1].	Domain
A	PF22082	2-thiouridine synthetase TtuA, N-terminal LIM domain (TtuA_LIM_N)	2-thiouridine synthetase TtuA, N-terminal LIM domain	TtuA is an oxygen-labile iron-sulfur protein that is involved in a post-transcriptional thiolation of RNA. The iron-sulfur cluster of TtuA is required for sulfurtransferase activity. The enzyme structure consists of three domains: a central catalytic ...	TtuA is an oxygen-labile iron-sulfur protein that is involved in a post-transcriptional thiolation of RNA. The iron-sulfur cluster of TtuA is required for sulfurtransferase activity. The enzyme structure consists of three domains: a central catalytic domain and two Zn-fingers [1]. This entry represents the N-terminal Zn-finger domain that share a significant similarity to LIM domains.	Domain
