Details | The asymmetric unit contains two biological assemblies. Each of them is an (alpha/beta)2 heterotetramer or a dimer of (alpha/beta) heterodimers. Subunits alpha (chains A, C, E, G) and beta (chains B, D, F, H) are, respectively, the N- and C-terminal products of autoproteolytic cleavage of a precursor. |
