Comments [?]

case <OC:Planctomycetes>
Function May function as a protein modifier covalently attached to lysine residues of substrate proteins. As this bacterium does not seem to encode proteasome subunits and proteasome ATPase adjacently to UBact, this tagging system may serve another role than targeting the modified proteins for degradation by proteasomes.
else
Function May function as a protein modifier covalently attached to lysine residues of substrate proteins. This may serve to target the modified proteins for degradation by proteasomes.
end case
case <FTTag:deamidation>
Ptm May be modified by deamidation of its C-terminal glutamine to glutamate by the adjacently encoded deamidase. This could be a prerequisite to the subsequent conjugation, as shown in the other prokaryotic ubiquitin-like protein Pup.
end case
Similarity Belongs to the ubiquitin-like protein UBact family.
