Homologous recombination is that which we are taught about in introductory biology class. It is the crossing-over process observed during meiosis, though it occurs in bacteria as well. The process involves pairing up of similar DNA sequences, with then one sequence replacing the other, or indeed for meiotic crossing over, with the generation of now two recombinant strands, one for each chromosome homolog, rather than just one. In either case, key is that it is DNA that is highly similar in terms of DNA sequence that is being either replaced or swapped. This allows for a replacement of alleles following horizontal gene transfer, or allele swapping...

... Belford and colleagues describe an elegant mutational strategy to engineer an intein with improved features to serve as a tool for protein purification. Previously, this group created a mini-intein by removing an internal domain encoding an endonuclease activity required for horizontal transfer of the intein gene.

CONT

L'épissage protéique se définit comme un évènement post-traductionnel qui conduit à la maturation d'une protéine précurseur, inactive en plusieurs protéines fonctionnelles. Durant cette maturation un ou plusieurs polypeptides (intéines) sont excisés du précurseur et les régions flanquantes (extéines) sont reléguées par une liaison peptidique.
