Comments [?]

case <FTGroup:1>
COFACTOR Name=[4Fe-4S] cluster; Xref=ChEBI:CHEBI:49883; Note=Binds 1 [4Fe-4S] cluster per subunit. Following nitrosylation of the [4Fe-4S] cluster binds 1 [4Fe-8(NO)] cluster per subunit.;
PTMThe Fe-S cluster can be nitrosylated by nitric oxide (NO).
PTMUpon Fe-S cluster removal intramolecular disulfide bonds are formed.
end case
