Genes optimized by evolution for accurate and fast translation encode in Archaea and Bacteria a broad and characteristic spectrum of protein functions
Abstract Background In many microbial genomes, a strong preference for a small number of codons can be observed in genes whose products are needed by the cell in large quantities.This codon usage bias (CUB) improves translational accuracy and speed and is one of several factors optimizing cell growth.Whereas CUB and the overrepresentation of indivi
