LOW-TEMPERATURE STUDY OF THE A-DNA FRAGMENT D(GGGCGCCC)
Overview
The structure of the A-type duplex d(GGGCGCCC) was determined from data, measured at 115 K to 2.0 A resolution. The space group, P4(3)2(1)2, is the, same as for the 293 K structure; cell dimensions are a = 42.74 (4), c =, 24.57 (1) A; R = 0.21 for 1694 observed reflections. The conformation and, hydration are similar at the two temperatures. The average displacement, parameters (B) for bases, sugars and phosphates all decrease by about 9 A2, relative to those found at 293 K. The individual values of B1/2 are, linearly related to the distance from the molecular center of mass.
