In the center there is a schematic of the mutual relationship of the monomers,in selected members of the family, as indi-cated by the twist angle of the dimer.TM1415 constitutes one of the ... atase. The indi vidualdimers are similar to the human IMPase. Additionally, the structures of two crystal forms of IMPase show significant differences. In the first crystal form, the tetrameric structure...
