Nuclear Magnetic Resonance Studies of Spherical Plant Viruses

NUCLEAR MAGNETIC RESONANCE STUDY OF THE STRUCTURE OF GLYOXALDIHYDRAZONE

Study of the nuclear magnetic resonance spectra of glyoxaldihydrazone in dimethylsulfoxide and deuterochlorofonn leads to the conclusion that this compound exists predominantly in non-chelate structure

Nuclear magnetic resonance and plant metabolic engineering.

Nuclear magnetic resonance (NMR) can be used to measure metabolite levels and metabolic fluxes, to probe the intracellular environment, and to follow transport and energetics nondestructively. NMR methods are therefore powerful aids to understanding plant metabolism and physiology. Both spectroscopy and imaging can help overcome the unique challenges that plants present to the metabolic enginee...

Nuclear magnetic resonance studies of phospholipid micelles.

The proton magnetic resonance spectrum of DL-a!-lecithin at 100 MHz in CHCJ solvent is reported. An analysis of the spectrum is made. The chemical shifts of the N-(CH& protons and the resonance peak associated with the condensed water molecule showed concentration dependence with the latter showing the more pronounced response. These chemical shift changes are interpreted in terms of micelle fo...

Structural studies of spherical viruses.

Tomato bushy stunt virus (TBSV) is probably the most suitable of the simple viruses for atomic resolution structure analysis. It is built from 180 copies of a coat protein subunit (Mw 41,000) and a single piece of RNA (MW 1.5 X 106) (1-3). There may also be a single copy of a large internal protein (MW 87,000) (a). The coat subunits form a T=3 icosahedral surface lattice. The symmetry of this l...
