    Protein Summary

    Pfam note: this protein shows distant similarity to the ASCH family (PF04266), but it forms its own family that has now been added to PFAM as DUF3850 (PF12961), a new member of the PUA clan (CL0178). It would be released in PFAM release 25.


    Gene NP_814290.1 from ENTEROCOCCUS FAECALIS V583 encodes a protein with 82 residues. The search results from NCBI sequence alignment indicates a conserved domain belonging to ASCH superfamily [Ref].  Dali searching results show that the protein is a structurally similar to the PUA domain, suggesting it may be involved in RNA recognition.   It has been reported that the deletion of PUA genes results in impaired growth (RluD) and competitive disadvantage (TruB) in Escherichia coli.  Suggestions have been put forward that, apart from their usual catalytic role, certain PUS enzymes (e.g. TruB) may also act as chaperones for RNA folding.  The interface interaction indicates that the biomolecule of protein NP_809782.1 should be a dimer.



    Figure 1. Protein NP_ NP_814290.1 is structurally similar to PUA protein. One cacodylate anion from crystallization is also modeled in the structure. 




    Figure 2. The biomolecule of NP_ NP_814290.1 is a dimer.
