1XY2: CRYSTAL STRUCTURE ANALYSIS OF DEAMINO-OXYTOCIN. CONFORMATIONAL FLEXIBILITY AND RECEPTOR BINDING
Science (1986) 232 p.633-636
Two crystal structures of deamino-oxytocin have been determined at better than 1.1A resolution from isomorphous replacement and anomalous scattering x-ray measurements. In each of two crystal forms there are two closely related conformers with disulfide bridges of different chirality, which may be important in receptor recognition and activation.
