Invariant amino acids essential for decoding function of polypeptide release factor eRF1.

abstract：:Various in vivo mutagenesis methods have been developed to facilitate fast and efficient continuous evolution of proteins in cells. However, they either modify the DNA region that does not match the target gene, or suffer from low mutation rates. Here, we report a mutator, eMutaT7 (enhanced MutaT7), with very fast in ...

abstract：:The process of strand exchange is considered to be the hallmark of DNA recombination. Proteins known to carry out such exchange are believed to operate via one or the other of two mechanisms. RecA-like proteins promote the formation of a three-stranded or triplex synaptic intermediate in which strand exchange occurs, ...
