Abstract
|
|
|
Ribonuclease inhibitor was purified from pig liver and crystallized at 21
degrees C from solutions containing dithiothreitol as an additive and ammonium
sulfate, lithium sulfate or combinations of both as precipitants. Crystals have
the symmetry of the tetragonal space group I4 with a = 134.9 A and c = 83.6 A,
and diffract to better than 3 A resolution. Self rotation functions and packing
density of the crystals are consistent with two molecules in the asymmetric unit.
