tetramer
tetramer
the monomeric structure is made up of two primary domains. Each has a central extended beta-sheet surrounded by alpha-helices, with a cleft between them which holds the cofactor. The second primary domain extends from residues 249 to 444 and has a central beta-sheet of seven strands surrounded by alpha-helices. This second beta-sheet is extended by the three beta-strands of the neighbouring dimer extension (residues 119-136 and 444-494) to make a beta-sheet of ten strands in the dimer structure. The finger extension (residues 119-136 and 444-480) forms a three-stranded beta-sheet extension which pulls the dimer structure together, but is also used as a hook to pull in a neighbouring dimer and form the basis of the hexameric structure
