4.3.3.6	dodecamer	12 * 29000, two interacting hexamers, analytical ultracentrifugation, 35320.7 Da determined by ESI-MS	724999	
4.3.3.6	hexamer	PdxS exists as a hexamer or dodecamer depending on species and makes a 1:1 complex with PdxT. Pyrococcus horikoshii PdxS forms hexamer in solution. It has a 37 amino acids insertion region, which is found in some archaeal PdxS proteins. This additional insertion perturbs dodecamer formation of Pyrococcus horikoshii PdxS	-, 723192	
4.3.3.6	homododecamer	Pdx1, random association pattern of up to 12 Pdx2 subunits to the Pdx1 dodecamer	726499	
4.3.3.6	homohexamer	6 * 37014, calculated, dynamic light-scattering analysis	721233	
4.3.3.6	homohexamer	gel filtration	-, 723192	
4.3.3.6	additional information	from crystal structure, the asymmetric unit contains 3 Rv2606c molecules, and the dodecameric structure of the protein can be generated by applying crystallographic I222 symmetry, interfaces for the formation of dodecameric structure, overview	-, 729134	
4.3.3.6	additional information	the pyridoxal 5'-phosphate synthase complex is made up of 24 protein units assembled like a cogwheel, a dodecameric Pdx1 to which 12 Pdx2 subunits attach. Macromolecular assembly is directed by an N-terminal
alpha-helix on the synthase. Interaction with the synthase subunit leads to glutaminase activation, resulting in formation of an oxyanion hole, a prerequisite for catalysis	716736	
4.3.3.6	oligomer	the intact enzyme includes 12 synthase and 12 glutaminase subunits	748203
