Codon Usage

Die Codon Usage beschreibt das Phänomen, dass Varianten des universellen genetischen Codes von verschiedenen Spezies unterschiedlich verwendet werden. Das heißt bestimmte Codons des degenerierten Codes werden bevorzugt benutzt, was letztlich der tRNA Konzentration innerhalb der Zelle entspricht. Die Codon Usage spielt eine große Rolle bei der Regulation der Proteinbiosynthese. Selten verwendete Codons können die Translation bremsen während häufig genutzte Codons die Translation beschleunigen können.

Bei der (aus Kostengründen häufig bevorzugten) gentechnischen Produktion menschlicher Proteine in Bakterien kann es daher von Vorteil sein, das in den Produzenten eingebrachte humane Gen in seiner "codon usage" dem Repertoire des Bakterienstamms anzugleichen und damit zu einer höheren Effizienz zu kommen.
