Conformational studies of mitochondrial DNA.
Ring DNA from rat liver mitochondria has been examined by circular dichroism (CD) in the region of the 225 to 320 m/∼ and the followings have been clarified. The ring DNA gives a CD spectral curve somewhat different from linear DNA from nuclei, showing a big positive peak at 266 m/∼ and a small negative band at 243 m!∼. That is, the positive CD band of ring DNA shifted by about 7 m/∼ to the sho...
متن کاملpostnatal studies of bats (pipistrellus kuhlii and miniopterus schreibersii) & histomorphology and histochemistry studies of organs and diseases of (neurergus microspilotus and n. kaiseri)
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
Quantitative studies of ribosome conformational dynamics.
The ribosome is a dynamic machine that undergoes many conformational rearrangements during the initiation of protein synthesis. Significant differences exist between the process of protein synthesis initiation in eubacteria and eukaryotes. In particular, the initiation of eukaryotic protein synthesis requires roughly an order of magnitude more initiation factors to promote efficient mRNA recrui...
متن کاملDFT Conformational Studies of a-Maltotriose
Recent DFT optimization studies on a-maltose improved our understanding of the preferred conformations of a-maltose. The present study extends these studies to a-maltotriose with three a-D-glucopyranose residues linked by two a-[1?4] bridges, denoted herein as DP-3’s. Combinations of gg, gt, and tg hydroxymethyl groups are included for both ‘‘c’’ and ‘‘r’’ hydroxyl rotamers. When the hydroxymet...
متن کاملVibrational and Conformational Studies of Cyclopropanecarboxaldehyde
The infrared (3500 to 40 cm-l) and Raman (3200 to 20 cm") spectra have been recorded for gaseous and solid cyclopropanecarboxaldehyde, c-C3H5CHO. Additionally, the Raman spectrum of the liquid has been recorded and qualitative depolarization values have been obtained. It has been determined that the conformer with the oxygen atom cis to the three-membered ring is the more stable form at ambient...
