Abstract:

eRF1a, one of the class-I release factors from ciliate Euplotes octocarinatus, has been crystallized by the vapor-diffusion method using polyethylene glycol 4000 as the precipitant at pH 7.5. The crystal belongs to space group P2 1 and the unit-cell parameters are a=90.4, b=107.9, c=114.8Å, bgr =94.2°. There appear to be four eRF1a molecules in the asymmetric unit.
