(ADP-ribosyl)transferases can perform two types of modifications: mono(ADP-ribosyl)ation and poly(ADP-ribosyl)ation. Mono(ADP-ribosyl)ation. Mono(ADP-ribosyl)transferases commonly catalyze the addition of ADP-ribose to arginine side chains using a highly conserved R-S-EXE motif of the enzyme. Visa mer ADP-ribosylation is the addition of one or more ADP-ribose moieties to a protein. It is a reversible post-translational modification that is involved in many cellular processes, including cell signaling, DNA repair, gene regulation Visa mer Many different amino acid side chains have been described as ADP-ribose acceptors. From a chemical perspective, this modification … Visa mer Apoptosis During DNA damage or cellular stress PARPs are activated, leading to an increase in the amount of poly(ADP-ribose) and a … Visa mer • Histone code • Cell signaling • PARP-1 • Cholera toxin Visa mer The first suggestion of ADP-ribosylation surfaced during the early 1960s. At this time, Pierre Chambon and coworkers observed the … Visa mer The source of ADP-ribose for most enzymes that perform this modification is the redox cofactor NAD . In this transfer reaction, the N-glycosidic bond of NAD that bridges the ADP-ribose molecule and the nicotinamide group is cleaved, followed by nucleophilic attack by … Visa mer Cancer PARP1 is involved in base excision repair (BER), single- and double-strand break repair, and chromosomal stability.
