DnaK-Dependent Accelerated Evolutionary Rate in Prokaryotes
Many proteins depend on an interaction with molecular chaperones in order to fold into a functional tertiary structure. Previous studies showed that protein interaction with the GroEL/GroES chaperonine and Hsp90 chaperone can buffer the impact of slightly deleterious mutations in the protein sequence. This capacity of GroEL/GroES to prevent protein misfolding has been shown to accelerate the ev...
متن کاملEvolutionary Genomics of Fast Evolving Tunicates
Tunicates have been extensively studied because of their crucial phylogenetic location (the closest living relatives of vertebrates) and particular developmental plan. Recent genome efforts have disclosed that tunicates are also remarkable in their genome organization and molecular evolutionary patterns. Here, we review these latter aspects, comparing the similarities and specificities of two m...
متن کاملDo Housekeeping Genes Exist?
The searching of human housekeeping (HK) genes has been a long quest since the emergence of transcriptomics, and is instrumental for us to understand the structure of genome and the fundamentals of biological processes. The resolved genes are frequently used in evolution studies and as normalization standards in quantitative gene-expression analysis. Within the past 20 years, more than a dozen ...
متن کاملEvolutionary rate variation in anthocyanin pathway genes.
Over a broad taxonomic range that spans monocots and dicots, upstream enzymes of the anthocyanin pigment pathway have evolved less rapidly than downstream enzymes. In this article we show that this pattern is also evident within the genus Ipomoea. Specifically, the most upstream enzyme, chalcone synthase (CHS-D), evolves more slowly than the two most downstream enzymes, ancyocyanidin synthase (...
