Comments [?]

case <OG:Chloroplast>
Function Acts as a processive, ATP-dependent zinc metallopeptidase.
else
Function Acts as a processive, ATP-dependent zinc metallopeptidase for both cytoplasmic and membrane proteins. Plays a role in the quality control of integral membrane proteins.
end case

Cofactor Zn(2+)
Note: Binds 1 zinc ion per subunit.
end case
Subunit Homohexamer.
case <OG:Chloroplast>
Subcellular location Plastid, chloroplast thylakoid membrane; Multi-pass membrane protein; Stromal side.
else case <OC:Cyanobacteria> and not <OC:Gloeobacter>
Subcellular location Cellular thylakoid membrane; Multi-pass membrane protein; Stromal side.
else case (defined <Property:Membrane> and <Property:Membrane=2>) or <OC:Gloeobacter>
Subcellular location Cell inner membrane; Multi-pass membrane protein; Cytoplasmic side.

Comments Chlamydiae have an N-terminal extension not found in other organisms. Not all proteins have 2 transmembrane domains. There are short paralogs in Haemophilus that are missing the N-terminal transmembrane section, they are annotated as atypical. Some plastids encode very long homologs that cannot bind zinc, they are annotated as atypical (CHLVU, HELSJ, OLTVI).
