Codon bias in Escherichia coli: The influence of codon context on mutation and selection
- 1997
-
Ingår i: NUCLEIC ACIDS RESEARCH. - : OXFORD UNIV PRESS. - 0305-1048. ; 25:7, s. 1397-1404
-
Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- The codon bias in Escherichia coli for all two-fold degenerate amino acids was studied as dependent on the context from the six bases in the nearest surrounding codons. By comparing the results in genes at different expression levels, effects that are due

Growth rate-optimised tRNA abundance and codon usage
- 1997
-
Ingår i: JOURNAL OF MOLECULAR BIOLOGY. - : ACADEMIC PRESS LTD. - 0022-2836. ; 270:4, s. 544-550
-
Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- The abundance of different tRNAs in Escherichia coil at different growth rates correlates strongly with the usage of the corresponding cognate codons. On the assumption that the investment in the translation system is optimised to provide a maximal growth

KINETICS OF SYNONYMOUS CODON CHANGE FOR AN AMINO-ACID OF ARBITRARY DEGENERACY
- 1995
-
Ingår i: JOURNAL OF MOLECULAR EVOLUTION. - : SPRINGER VERLAG. - 0022-2844. ; 41:3, s. 345-352
-
Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- The kinetics of synonymous codon change and species divergence is described in a matrix formalism that is equally applicable to all levels of codon degeneracy and all levels of codon or nucleotide bias. Based an the formalism it is possible to calculate t

PERIODIC SELECTION AND HITCHHIKING IN A BACTERIAL POPULATION
- 1995
-
Ingår i: JOURNAL OF THEORETICAL BIOLOGY. - : ACADEMIC PRESS (LONDON) LTD. - 0022-5193. ; 173:3, s. 307-320
-
Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- The accumulation of a neutral marker in a bacterial population under balanced growth in a chemostat follows a jagged curve as adaptive variants continuously appear and sweep the population. Such periodic selection curves are simulated in the present work

Selection intensity for codon bias and the effective population size of Escherichia coli
- 1996
-
Ingår i: GENETICS. - : GENETICS. - 0016-6731. ; 142:4, s. 1379-1382
-
Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- The selection intensity for codon bias and the synonymous diversity have been used in the recent literature to estimate the effective population size of Escherichia coli. The results have varied between 10(5) and 10(8). It is suggested here that most of t
