Symmetric Recursive Sequences Mod M,s that catalyze the cleavage of the linkage between nicotinamide and ribose and the transfer of ADP-ribose to a nucleophilic acceptor. Such ADP-ribose transfer reactions represent a versatile mechanism for the posttranslational modification of proteins. For example, poly(ADP-ribose) polymerase catal

Daniel C. Fielder,Cecil O. Alfordt has proven extremely fruitful in other areas as well. When looking through his eyes at the structure of pyridine nucleotides, we see two activated groups (Fig. 1): Active ADP-ribose and active AMP in NAD, and the corresponding groups in NADP as well, but extended by a 2’-phosphate residue. Recogni

Cher Ming Tan,Wei Li,Yuejin Houe level of poly(ADP-ribose) is stable in cells but if the cells are treated with a carcinogen (e.g. an alkylating agent) the level of poly(ADP-ribose) sharply increases in response to DNA damage (2). The short half-life measured . after treatment of cells with alkylating agents (2) suggests that pol

Introduction to Algebraic Geometry, transfer to other acceptor proteins and subsequent elongation (1). DNA is required as a coenzyme, and an enzyme-associated DNA, defined as sDNA (2), can be isolated which is more efficient than crude calf thymus DNA (3). It was reported that introduction of cleavage sites into double-stranded DNA c

Construction of Irreducible Polynomials,e poly(ADP-ribose) chain is elongated by the repetitive “distal” addition of further ADP-ribose residues to the 2′OH end (1). However the first product of poly(ADP-ribose) synthesis is an auto-modified polymerase (1–3), which is difficult to reconcile with distal addition. For this and other reasons
