Inside Cover: Implantation of Post-translational Tyrosylprotein Sulfation into a Prokaryotic Expression System (ChemBioChem 3/2011)
The inside cover picture shows the initiation of post-translational protein sulfation, which is involved in a variety of biological events such as inflammation, signal pathways and virus infection. For details of how sulfated proteins were efficiently produced through co-expression of related enzymes and the protein target in a bacterial system see the communication by Y.-S. Yang et al. on p. 377 ff.
