Letter: Specificity in initiation of mRNA translation

Theoretical modelling of protein synthesis

This article provides an overview of the use of mathematical and computer modelling in furthering the understanding of protein synthesis. In particular, we discuss issues such as the nature of the rate limiting step(s), error rates, tRNA-codon adaptation, codon bias, attenuation control, and problems of selection and error corrections, focussing on their theoretical treatment.

Models for mRNA translation: theory versus experiment

Three models for mRNA translation are discussed in the light of available experimental data. It is concluded that the elongation rates vary along a messenger, possibly as a result of a coupling between ribosome movement and mRNA secondary structure. Some promising areas of further experimentation are indicated.
