Genes conding for mitochondrial proteins are more strongly biased in Kluyveromyces lactis than in Saccharomyces cerevisiae
Tóm tắt
The codon bias index (CBI) of several genes of Kluyveromyces lactis was calculated and compared with corresponding data from Saccharomyces cerevisiae. Genes encoding cytoplasmic as well as mitochondrial proteins were analyzed. The CBI of K. lactis and S. cerevisiae genes are similar for the majority of the cases considered with the exception of genes encoding mitochondrial proteins which display higher CBI values in K. lactis, indicating a higher level of gene expression. This could be related to the key role played by mitochondria in this yeast.
