Role of GC-biased mutation pressure on synonymous codon choice in Micrococcus luteus, a bacterium with a high genomic GC-content.
The GC (G + C, or G or C)-contents of codon silent positions in all two-codon sets and three codons AUY/A (IIe), and in most of the family boxes of Micrococcus luteus (genomic GC-content: 74%) are 95% to 100% in both the highly and weakly expressed genes. In some family boxes, there is a decrease in NNC codons and an increase in NNG codons from the highly expressed to weakly expressed genes wit...
متن کاملVariation in G + C-content and codon choice: differences among synonymous codon groups in vertebrate genes.
The relationship between G + C-content and codon usage in genes of human, mus, rat, bovine and chicken nuclear genomes was investigated. Correlation and lineal regression analyses were carried out on plots that related the frequency of each codon within each synonymous codon group to the G + C-content of the coding sequence as a whole. Under GC pressure, in most of the quartet codon groups ther...
متن کاملDNA-relaxing enzyme from Micrococcus luteus.
A DNA-relaxing enzyme which catalyzes the conversion of superhelical DNA to a non-superhelical covalently closed form has been purified from Micrococcus luteus to near homogeneity by two chromatographic steps. The enzyme is a single polypeptide chain. As determined by sodium dodecyl sulfate - polyacrylamide gel electrophoresis and gel filtration on Sephadex G 150, the molecular weight is 115,00...
متن کاملBinding of Dissolved Strontium by Micrococcus luteus.
Resting cells of Micrococcus luteus have been shown to remove strontium (Sr) from dilute aqueous solutions of SrCl(2) at pH 7. Loadings of 25 mg of Sr per g of cell dry weight were achieved by cells exposed to a solution containing 50 ppm (mg/liter) of Sr. Sr binding occurred in the absence of nutrients and did not require metabolic activity. Initial binding was quite rapid (<0.5 h), although a...
متن کاملSynonymous Codon Substitution Matrices
Observing differences between DNA or protein sequences and estimating the true amount of substitutions from them is a prominent problem in molecular evolution as many analyses are based on distance measures between biological sequences. Since the relationship between the observed and the actual amount of mutations is very complex, more than four decades of research have been spent to improve mo...
