Chain Elongation of Aldonolactones

Journal of Carbohydrate Chemistry, 1990
ABSTRACT As an alternative to the classical Reformatsky-type branching reaction of aldonolactones, ethyl trimethylsilylacetate, methyl 2-trimethylsilyl-propionate, trimethylsilylacetonitrile or alkyl 2-(trimethylsilylmethyl)-acrylates in the presence of catalytic amounts of tetra-n-butyl-ammonium fluoride can be used.

Chain elongation of eicosapentaenoic acid in the macrophage

Biochimica et Biophysica Acta (BBA) - Lipids and Lipid Metabolism, 1990
In order to elucidate the metabolic fate of eicosapentaenoic acid (20:5 (n-3], a major n-3 fatty acid constituent of fish oil, resident and casein-elicited mouse peritoneal macrophages were incubated with [3H]20:5 (n-3). Comparative experiments with arachidonic acid (20:4 (n-6] were also conducted.

Peptide-chain elongation in eukaryotes

Molecular Biology Reports, 1994
The elongation phase of translation leads to the decoding of the mRNA and the synthesis of the corresponding polypeptide chain. In most eukaryotes, two distinct protein elongation factors (eEF-1 and eEF-2) are required for elongation. Each is active as a complex with GTP. eEF-1 is a multimer and mediates the binding of the cognate aminoacyl-tRNA to the

The S1 Factor in Peptide Chain Elongation

Nature, 1970
Aminoacyl-tRNA becomes attached to the ribosome as part of an S3 factor–GTP–aminoacyl-tRNA complex. GTP is then cleaved and an S3 factor–GDP complex is released. The S1 factor promotes the re-formation of the S3 factor–GTP–aminoacyl-tRNA complex from the S3 factor–GDP complex, aminoacyl-tRNA and GTP.

Chain elongation in the isoprenoid biosynthetic pathway

Current Opinion in Chemical Biology, 1997
Isoprenyl diphosphate synthases catalyze addition of allylic diphosphate primers to the isoprene unit in isopentenyl diphosphate to produce polyisoprenoid diphosphates with well defined chain lengths. Phylogenetic correlations suggest that the synthases which catalyze formation of isoprenoid diphosphates with (E) double bonds have evolved from a common

A mathematical model for elongation of a peptide chain

Bulletin of Mathematical Biology, 2003
A mathematical model is presented for the steps in the elongation process, and the steady-state elongation rate as a function of the amino acid concentrations is found. In addition, the reset sub-process of the elongation process is modeled. The rate of elongation of peptide chains is found to be a function of the concentration of the amino acid to be ...

Mutant Hemoglobins Having Elongated Chains

Hemoglobin, 1978
Globin subunits may be elongated because of a base substitution in the termination codon, a crossover out of phase (frame shift) or a crossover in phase. This review presents structural, genetic, biosynthetic and clinical information on the eight variants having elongated chains which have been described to date.

A New Concept of the Function of Elongation Factor 1 in Peptide Chain Elongation

European Journal of Biochemistry, 1976
An entirely new model for the mechanism of elongation factor 1 (EF‐1) function is presented. Experiments, in which mixtures of [3H]EF‐1, ribosomes from Krebs II ascites cells and various additional co‐factors were analyzed by chromatography on Sepharose 6B, show that EF‐1 binds to the ribosome early in the translation process and remains bound on the ...

Model for the elongation of polynucleotide chains by polynucleotide phosphorylase

Journal of Molecular Biology, 1970
Abstract The experiments described in this paper were designed to elucidate the mechanism of elongation of a polynucleotide chain catalysed by polynucleotide phosphorylase. The problem has been approached in three different ways, essentially: (1) examination of the size distribution of the end products isolated during the course of the reaction; (2 ...
