Protein degradation is an essential component of regulation because proteins can become misfolded, damaged, or unnecessary. Proteasomes and their homologues vary greatly in complexity: from HslV (heat shock locus v), which is encoded by 1 gene in bacteria, to the eukaryotic 20S proteasome, which is encoded by more than 14 genes [1]. Recently evidence of two novel groups of bacterial proteasomes was proposed. The first is Anbu, which is sparsely distributed among cyanobacteria and proteobacteria [1]. The second is call beta-proteobacteria proteasome homologue (BPH) [1].

A study revealed that the C-terminal 52 residues of the Rpn2 C-terminal domain are responsible for mediating interactions with the ubiquitin-binding subunit Rpn13. Futhermore, the extreme C-terminal 20 or 21 residues of Rpn2 (926-945 or 925-945) of S. cerevisiae, were shown to be equally effective at binding Rpn13. Multiple sequence alignments indicate that Rpn2 orthologs are highly conserved in this C-terminal region and share characteristic acidic, aromatic, and proline residues, suggesting a common function. In the structure of Rpn2 from S. cerevisiae , this region is exposed and disordered, and is thus accessible for associating with Rpn13. The Rpn2 binding surface of human Rpn13 has been mapped by nuclear magnetic resonance titration to one surface of its Pru domain [1].
