Abstract
The human antiretroviral factor APOBEC3G (A3G) deaminates the newly synthesized minus strand of the human immunodeficiency virus 1 (HIV-1), which results in the abolition of the infectivity of virus-infectivity-factor (Vif)-deficient HIV-1 strains.1-6 A unique property of A3G is that it deaminates a CCC hot spot that is located close to the 5' end more effectively than one that is less close to the 5' end. However, the mechanism of this process is elusive as it includes nonspecific binding of A3G to DNA and sliding of A3G along the DNA strand. Therefore, this process cannot be analyzed by existing methods using the Michaelis-Menten theory. A new real-time NMR method has been developed to examine the nonspecific binding and the sliding processes explicitly, and it was applied to the analysis of the deamination by A3G. As a result, the location-dependent deamination can be explained by a difference in the catalytic rates that depend on the direction of the approach of A3G to the target cytidine. Real-time NMR experiments also showed that A3G deaminates CCCC tandem hotspots with little redundancy, which suggests that A3G efficiently mutates many CCC hotspots that are scattered throughout the HIV-1 genome.

Kinetic analysis of protein aggregation monitored by real-time 2D solid-state NMR spectroscopy
Kinetic analysis of protein aggregation monitored by real-time 2D solid-state NMR spectroscopy Abstract It is shown that real-time 2D solid-state NMR can be used to obtain kinetic and structural information about the process of protein aggregation. In addition to the incorporation of kinetic information involving intermediate states, this approach can offer atom-specific resolution for all detectable species. The analysis was carried out using experimental data obtained during aggregation of the 10.4 kDa Crh protein, which has been shown to involve a partially unfolded intermediate...
