CC   -!- SUBUNIT: Toroid-shaped homohexamer that has a central cavity of about
CC       38 Angstroms diameter. {ECO:0000250|UniProtKB:P67272}.
CC   -!- DOMAIN: Is organized into three distinct structural domains with
CC       interconnecting topological connectivities. The two NIF3 domains at the
CC       N- and C-terminus of the protein have the same overall fold as
CC       canonical NIF3-like proteins. The middle region of the polypeptide
CC       (residues 126-236) bulges out between the two NIF3 domains and is
CC       structured as a classical PII-like fold. The two entries to the central
CC       hollow space are capped by the two PII-like domain trimers. The
CC       trimeric PII domain may play a ligand induced signaling role and
CC       probably regulates the function of the NIF3-like domains.
CC       {ECO:0000250|UniProtKB:P67272}.
CC   -!- SIMILARITY: Belongs to the GTP cyclohydrolase I type 2/NIF3 family.
CC       {ECO:0000305}.
