We used structure prediction programs that identified extensive heptad repeat sequences in b-subunits from a variety of ATP synthases. Heptad repeats are often indicative of the propensity to form left-handed coiled coils. Molecular modeling strongly suggested that the E. coli subunit b dimer could...
Now that mills with proper worki1Jg plant are being granted leases for a fixed term of years for valuable timber areas, the first es~;ential change to be enforced is to levy all royalty eharges, as is already done in the case of redgum, on the full sl~pe.r ficial contents of...
The key splicing regulators that orchestrate tissue-specific AS programmes in brain20–25, heart26–32, skeletal muscle development33–37 or T-cell activation38–40 are well characterized; however, neither the full extent of transcript diversity nor the regulatory factors that drive isoform ...

The ENDOR results permitted full characterization of hyperfine couplings to HN7 and the two amino protons (the HN10s). From these results, and those from two other systems containing N7-protonated guanine bases, reaction mechanisms are proposed to account for formation of the products.doi:10.1080...
Full size image For each of these constructs, the MD trajectory was recorded using Amber1641program equipped with ff14SB42force field in explicit TIP3P43water. The topology and force-field parameters of the R1 tag were as reported previously44,45. The simulations were conducted using NPT ensembl...
In this manner, data from the on-stream energy dispersive X-ray analyzer can be used to their full advantage, and communication between operator and extraction processes improved. The simulation control system block for the coun- tercurrent extraction processes is shown in Fig. 1. The figure ...
Finally, new results of recent electron spin resonance measurements on irradiated polymers are presented and discussed in the framework of carbonaceous clusters and polymeric conductivity.Access through your organization Check access to the full text by signing in through your organization.
