The protein

Protein family

• bacterial [SW|ribosomal protein] bL31 family (with [protein|DAE7AB27A4C42BF50556BB76F33BEFA8DF35EA3A|RpmEB], according to UniProt)

Paralogous protein(s)

• [protein|DAE7AB27A4C42BF50556BB76F33BEFA8DF35EA3A|RpmEB]

[SW|Cofactors]

• requires zinc for activity [Pubmed|19648245,15049826]

Structure

• [PDB|3J9W] (the [SW|ribosome]) [Pubmed|25903689]

Additional information

• Under conditions of zinc starvation, RpmE is replaced by its paralog [protein|DAE7AB27A4C42BF50556BB76F33BEFA8DF35EA3A|RpmEB], that does not require zinc [Pubmed|15049826]
