  2.4.2.17 | homohexamer or heterooctamer |
the long-form enzyme is a homohexamer with each chain comprised of the catalytic core, and a covalent C-terminal regulatory domain containing the allosteric binding site for histidine. The short-form is a hetero-octamer containing two catalytic dimers that associate with a second discrete domain (denoted HisZ) for allosteric regulation by the binding of histidine |
