Poulter, Charles Dale | Yeast squalene synthase. A mechanism for addition of substrates and activation by NADPH | Squalene synthase catalyzes the condensation of two molecules of farnesyl diphosphate (FPP) to give presqualene diphosphate (PSPP) and the subsequent reductive rearrangement of PSPP to squalene. Previous studies of the mechanism of addition of FPP to the enzyme have led to conflicting interpretation... | Enzyme Activation; Sesquiterpenes; Kinetics | 1993-04-15 |

Poulter, Charles Dale | Farnesyl pyrophosphate synthetase. Mechanistic studies of the 1'-4 coupling reaction with 2-fluorogeranyl pyrophosphate. | The mechanism of the 1'-4 coupling reaction between isopentenyl pyrophosphate and geranyl pyrophosphate catalyzed by farnesyl pyrophosphate synthetase from porcine liver was studied with the allylic substrate analogue 2-fluorogeranyl pyrophosphate. 2-Fluorogeranyl pyrophosphate is an alternate subst... | Kinetics; Liver; Mass Spectrometry; Organophosphorus Compounds; Protein Binding | 1978-10-25 |

Gesteland, Raymond F. | Translation of Rl7 RNA fragments | Examination of the events during infection of cells by RNA phages reveals phemonomena that are surprisingly complex for a virus that has only enough information to code for three to four proteins. The coat protein is synthesized at a rapid rate through most of the infectious cycle making it the pre... | Electrophoresis; RNA, Messenger; Peptide Biosynthesis; Kinetics | 1969 |

Poulter, Charles Dale | Prenyltransferase. Kinetic studies of the 1'-4 coupling reaction with avian liver enzyme. | Prenyltransferase catalyzes the sequential, irreversible 1'-4 condensation of isopentenyl-PP with dimethylallyl-PP and geranyl-PP to yield farnesyl-PP. A kinetic study shows substrate inhibition by isopentenyl-PP at concentrations above 0.7 microM when the concentration of geranyl-PP is 1.0 microM o... | Birds; Kinetics; Structure-Activity Relationship; Substrate Specificity | 1979-10-10 |

Thomas, Kirk R.; Capecchi, Mario R. | Nonreciprocal exchanges of information between DNA duplexes coinjected into mammalian. cell nuclei | We have examined the mechanism of homologous recombination between plasmid molecules coinjected into cultured mammalian cells. Cell lines containing recombinant DNA molecules were obtained by selecting for the reconstruction of a functional Neor gene from two plasmids that bear different amber mutat... | Animals; Cells, Cultured; DNA Restriction Enzymes; Kinetics | 1985-01 |
