Abstract
The ubiquitous and essential nature of DNA predicts that enzymes responsible for DNA synthesis evolved early and share a common design and mechanism of action. DNA polymerases from many different organisms do exhibit striking similarities in their overall architecture, the design of the catalytic site, and the mechanism of nucleotidyl transfer. In spite of these shared features, however, DNA polymerases display an astonishing variety in structure and function, ranging from single subunit enzymes specialized for DNA repair to complex multi-protein holoenzymes responsible for genomic DNA replication. This review uses a few well-characterized model systems to summarize our current understanding of the workings of DNA polymerases in DNA metabolism.

Catalytic C-H bond activation as a tool for functionalization of heterocycles
The major topic is the functionalization of heterocycles through catalyzed C-H bond activation. The strategies based on C-H activation not only provide straightforward formation of C-C or C-X bonds but, more importantly, allow for the avoidance of pre-functionalization of one or two of the cross-coupling partners. The beneficial impact of ...read more
