A functional recT gene for recombineering of Clostridium

Abstract

Recombineering is an efficient genetic manipulation method employing the mechanism of phagenic RecT-mediated homologous recombination. To develop a recombineering method for Clostridium, a putative recT gene (CPF0939) from Clostridium perfringens genome was functionally verified in a clostridial host Clostridium acetobutylicum. We show that a short synthetic oligonucleotide can be introduced into the target site for specific point mutation. This functional recT gene would therefore contribute to development of recombineering tools for Clostridium.
