Abstract:
A protein mating pheromone Er-1 from the ciliate Euplotes raikovi has been crystallized from (NH4)2SO4 in two forms. Both are suitable for structural studies to at least 2.8 A resolution. Both unit cell sizes are consistent with a tetramer of molecular weight 17,640 in the asymmetric unit.
