Infrared vibrational CD (VCD) of a small peptide, L-alanyl-L-alanyl-L-alanine (Ala3), and a peptide model, N-acetyl-L-alanine-N'-methyl-amide (AAMA), in the 1550-1750-cm-1 region has been observed. The "coupled oscillator" VCD feature observed for Ala3 in the amide I region is interpreted in terms of a solution structure stabilized by the electrostatic(More)
The bending of double-stranded(ds) DNA on the nano-meter scale plays a key role in many cellular processes such as nucleosome packing, transcription-control, and viral-genome packing. In our recent study, a nanometer-sized dsDNA bent into a D shape was formed by hybridizing a circular single-stranded(ss) DNA and a complementary linear ssDNA. Our(More)
