The proteins in this family are located in the mitochondrion. The family includes ribosomal protein L51, and S25. This family also includes mitochondrial NADH-ubiquinone oxidoreductase B8 subunit (CI-B8) EC:1.6.5.3. It is not known whether all members of this family form part of the NADH-ubiquinone oxidoreductase and whether they are also all ribosomal proteins. Structurally related to thioredoxin-fold.

DnaJ domains (J-domains) are associated with hsp70 heat-shock system and it is thought that this domain mediates the interaction. DnaJ-domain is therefore part of a chaperone (protein folding) system. The T-antigens, although not in Prosite are confirmed as DnaJ containing domains from literature [2].
Cyclophilin type peptidyl-prolyl cis-trans isomerase/CLD
The peptidyl-prolyl cis-trans isomerases, also known as cyclophilins, share this domain of about 109 amino acids. Cyclophilins have been found in all organisms studied so far and catalyse peptidyl-prolyl isomerisation during which the peptide bond pr ...
The peptidyl-prolyl cis-trans isomerases, also known as cyclophilins, share this domain of about 109 amino acids. Cyclophilins have been found in all organisms studied so far and catalyse peptidyl-prolyl isomerisation during which the peptide bond preceding proline (the peptidyl-prolyl bond) is stabilised in the cis conformation. Mammalian cyclophilin A (CypA) is a major cellular target for the immunosuppressive drug cyclosporin A (CsA). Other roles for cyclophilins may include chaperone and cell signalling function [1].

Members of this family include the DEAD and DEAH box helicases. Helicases are involved in unwinding nucleic acids. The DEAD box helicases are involved in various aspects of RNA metabolism, including nuclear transcription, pre mRNA splicing, ribosome biogenesis, nucleocytoplasmic transport, translation, RNA decay and organellar gene expression.
The Prosite family is restricted to DEAD/H helicases, whereas this domain family is found in a wide variety of helicases and helicase related proteins. It may be that this is not an autonomously folding unit, but an integral part of the helicase.

A 4'-phosphopantetheine prosthetic group is attached through a serine. This prosthetic group acts as a a 'swinging arm' for the attachment of activated fatty acid and amino-acid groups. This domain forms a four helix bundle. This family includes members not included in Prosite. The inclusion of these members is supported by sequence analysis and functional evidence. The related domain of Swiss:P19828 has the attachment serine replaced by an alanine.
KH-domain-like of EngA bacterial GTPase enzymes, C-terminal
The KH-like domain at the C-terminus of the EngA subfamily of essential bacterial GTPases has a unique domain structure position. The two adjacent GTPase domains (GD1 and GD2), two domains of family MMR_HSR1, Pfam:PF01926, pack at either side of the ...
The KH-like domain at the C-terminus of the EngA subfamily of essential bacterial GTPases has a unique domain structure position. The two adjacent GTPase domains (GD1 and GD2), two domains of family MMR_HSR1, Pfam:PF01926, pack at either side of the C-terminal domain. This C-terminal domain resembles a KH domain but is missing the distinctive RNA recognition elements. Conserved motifs of the nucleotide binding site of GD1 are integral parts of the GD1-KH domain interface, suggesting the interactions between these two domains are directly influenced by the GTP/GDP cycling of the protein. In contrast, the GD2-KH domain interface is distal to the GDP binding site of GD2. This family has not been added to the KH clan since SCOP classifies it separately due to its missing the key KH motif/fold.
