The influence of the size and nature of basic activators on Clostridium perfringens polynucleotide phosphorylase-catalysed polyadenylic acid synthesis.
1. Basic oligo- and poly-(amino acids) stimulate polyadenylic acid synthesis by purified Clostridium perfringens polynucleotide phosphorylase (nucleoside diphosphate-polyribonucleotide nucleotidyltransferase, EC 2.7.7.8). 2. The effectiveness of the activators increases with chain length up to approx. 20-30 residues. 3. Polymers of the l and dl series are equally effective on a weight-for-weigh...
متن کاملPolynucleotide phosphorylase of Micrococcus lysodeiktpcus. III. The apparent arsenolysis of nucleoside diphosphates by polynucleotide phosphorylase.
The enzyme, polynucleotide phosphorylase, catalyzes the polymerization of nucleoside diphosphates to polyribonucleotides with the formation of inorganic orthophosphate (1, 2). The reaction is readily reversible, and the phosphorolysis of polyribonucleotides has been studied extensively (3-6). Several recent reviews (7-9) afford extensive summaries of the literature. In the accompanying paper (l...
متن کاملFrom polynucleotide phosphorylase to neurobiology.
In the fall of 1944, I enrolled at the Hebrew University of Jerusalem. The student body numbered about 700 and the choice of faculties was somewhat limited.My hopewas to study medicine, but the plans to open a medical school were still at the drawing board stage. I therefore chose to study chemistry with biochemistry and bacteriology as minor subjects, which I thought I would need later if I we...
متن کاملThe origin of polynucleotide phosphorylase domains.
In this report, we document the presence of polynucleotide phosphorylase (PNPase) in the animal eukaryotes. These proteins contain several domains, including 2 RNase PH domains (PNPase 1 and PNPase 2) which are closely related functionally and in sequence similarity to ribonuclease PH (RPH) protein. Phylogenetic analysis of the gene genealogy of these three domains suggests that PNPase was form...
متن کاملThe mechanism of action of polynucleotide phosphorylase.
The purpose of this paper is to review certain aspects of the mechanism of action of polynucleotide phosphorylase and to present, rather briefly, some recent findings. The discussion will be concerned with studies carried out by S. Ochoa and his associates a t New York University, New York, N. Y., and with work done a t the National Institutes of Health. Reference will also be made to some rece...
