Crystallization and Preliminary Crystallographic Studies of Luffaculin 1, a Ribosome-inactivating Protein from the Seeds of Luffa Acutangula

摘要

cqvip:Luffaculin 1 purified from the seeds of Luffa acutangula belongs to the type 1 ribosome-inactivating proteins (RIPs). It has been crystallized by the vapor-diffusion method using polyethylene glycol as a precipitant. The crystal is of space group P1 with a = 39.135, b = 46.813, c = 83.571, α = 89.068, β = 80.009 and γ = 72.143°, and has two molecules per asymmetric unit. X-ray data have been collected to be 1.4 using a synchrotron source.
