This domain contains a P-loop (Walker A) motif, suggesting that it has ATPase activity, and a Walker B motif. In tRNA(Met) cytidine acetyltransferase (TmcA) it may function as an RNA helicase motor (driven by ATP hydrolysis) which delivers the wobble base to the active centre of the GCN5-related N-acetyltransferase (GNAT) domain [1]. It is found in the bacterial exodeoxyribonuclease V alpha chain (RecD), which has 5'-3' helicase activity. It is structurally similar to the motor domain 1A in other SF1 helicases [2].
The S4 domain is a small domain consisting of 60-65 amino acid residues that was detected in the bacterial ribosomal protein S4, eukaryotic ribosomal S9, two families of pseudouridine synthases, a novel family of predicted RNA methylases, a yeast pro ...
The S4 domain is a small domain consisting of 60-65 amino acid residues that was detected in the bacterial ribosomal protein S4, eukaryotic ribosomal S9, two families of pseudouridine synthases, a novel family of predicted RNA methylases, a yeast protein containing a pseudouridine synthetase and a deaminase domain, bacterial tyrosyl-tRNA synthetases, and a number of uncharacterized, small proteins that may be involved in translation regulation [1]. The S4 domain probably mediates binding to RNA.
RNA cyclases are a family of RNA-modifying enzymes that are conserved in all cellular organisms. They catalyse the ATP-dependent conversion of the 3'-phosphate to the 2',3'-cyclic phosphodiester at the end of RNA, in a reaction involving formation o ...
RNA cyclases are a family of RNA-modifying enzymes that are conserved in all cellular organisms. They catalyse the ATP-dependent conversion of the 3'-phosphate to the 2',3'-cyclic phosphodiester at the end of RNA, in a reaction involving formation of the covalent AMP-cyclase intermediate [1]. The structure of RTC demonstrates that RTCs are comprised two domain. The larger domain contains an insert domain of approximately 100 amino acids [1].

This entry represents the first KH domain in the KRR1 protein [1]. Krr1 is a ribosomal assembly factor. The KH1 domain is a divergent KH domain that lacks the RNA-binding GXXG motif and is involved in binding another assembly factor, Kri1 [1].
KRR1 small subunit processome component, second KH domain
This is the second K homology domain (KH2) found in KRR1 small subunit processome component from the fungus Chaetomium thermophilum and similar eukaryotic sequences.

This domain is found at the N-terminal end of a group of archaeal proteins, including Uncharacterized NOP5 family protein MJ0694 from Methanocaldococcus jannaschii. This domain interacts with fibrillarin, the other subunit of a complex that is critical to modify and process ribosomal RNAs [1-5]. This domain shows a highly conserved folded structure despite low sequence similarity among homologs. It shows four beta-sheets surrounded by four alpha- helices [6] and is found associated with Pfam:PF01798.
