英文摘要: Crystals of pokeweed antiviral protein (PAP) from seeds of Phytolacca americana with high diffraction ability were grown from high protein concentration (100 mg/mL) solution at high temperature (33 degrees C). The crystal structure was solved by use of molecular replacement method and refined by use of molecular dynamic method at 0.25 nm to an R factor of 18.15% with standard deviations from standard geometry of 0.001 6 nm and 2.04 degrees for bond lengths and bond angles, respectively. Comparison with two other PAPs revealed, near the active center, a sequence and structure-variable region, consisting of the loop connecting the fifth beta-strand with the second a-helix and including a proposed active residue, suggesting this loop probably to be related to difference in activity.
