This volume focuses on mono-ADP-ribosylation and enzymes that use NAD+ including Sirtuins, PARPs, and bacterial and eukaryotic ADP-ribosyltransferases. The chapters in this book are organized into eight parts, and offer detailed descriptions of key protocols used to study topics such as in vitro techniques for ADP-ribosylation substrate identification; biochemical and biophysical assays of PAR-WWE domain interactions; monitoring expression and enzyme activity of ecto-ARTCs; HPLC-based enzymes assays for Sirtuins; and identifying target RNAs of PARPs. Written in the highly successful Methods...
