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