Ap4A and Other Dinucleoside Polyphosphates is the first compilation of contributions from major investigators involved in studying the chemistry and biology of dinucleoside polyphosphates. The book features reviews and original research (including unpublished and anecdotal material) covering the whole area of dinucleoside polyphosphate research from its inception to the present day. Ap4A and Other Dinucleoside Polyphosphates will be a useful reference for biological scientists studying nucleotide metabolism, cell signalling, DNA replication and repair, and cellular response to stress.
