WebAug 30, 1991 · Abstract. The 3 angstrom resolution crystal structure of the Escherichia coli catabolite gene activator protein (CAP) complexed with a 30-base pair DNA sequence shows that the DNA is bent by 90°. This bend results almost entirely from two 40° kinks that occur between TG/CA base pairs at positions 5 and 6 on each side of the dyad axis of … WebA calcium analog of strontioborite, namely, Ca[B 8 O 11 (OH) 4], is synthesized under hydrothermal conditions (T = 270°C, P = 20 atm) within the framework of the study of the phase formation in the CaCl 2 · Rb 2 CO 3 · B 2 O 3 system.
