Aminoacylation:
A reaction that introduces an aminoacyl group to a molecule. Transfer rna aminoacylation is the first step in Genetic translation.

Genome-wide Analysis of Aminoacylation (Charging) Levels of tRNA Using Microarrays
Department of Biochemistry and Molecular Biology, University of Chicago
We describe a method for microarray analysis to determine relative aminoacylation levels of all tRNAs from S. cerivisiae.

Simple and Robust in vivo and in vitro Approach for Studying Virus Assembly
1Department of Plant Pathology and Microbiology, University of California, Riverside, 2Department of Bioengineering, University of California, Riverside
A simple, efficient and robust way to synchronize the delivery of multiple viral components to plant cells via Agrobacterium-mediated transient expression is described. This approach is amenable for studying replication, encapsidation followed by in vitro reassembly of non-viral components into genome depleted optical viral ghosts suitable for biomedical applications.

Substrate Generation for Endonucleases of CRISPR/Cas Systems
Prokaryotic Small RNA Biology, Max-Planck-Institute for Terrestrial Microbiology
CRISPR/Cas systems mediate adaptive immunity in Bacteria and Archaea. Many Cas proteins are proposed to act as endoribonucleases acting on crRNA precursors of varying length. Here we illustrate three different approaches to generate pre-crRNA substrates for the biochemical analysis of Cas endonuclease activity.
