recombinant NEBU 37 65 Heat

This product will be discontinued on 12/15/2021 and is replaced with RecA (NEB #M0249).

RecAf is His-tagged. Native RecA is also available as a separate product.

RecAf is a N-terminal 6X His tagged recombinant protein.  E. coli RecA is necessary for genetic recombination, reactions involving DNA repair and UV-induced mutagenesis. RecA promotes the autodigestion of the lexA repressor, umuD protein and lambda repressor. Cleavage of LexA derepresses more than 20 genes. In vitro studies indicate that in the presence of ATP, RecA promotes the strand exchange of single-strand DNA fragments with homologous duplex DNA. The reaction has three distinct steps: (i) RecA polymerizes on the single-strand DNA, (ii) the nucleo­protein filament binds the duplex DNA and searches for a homologous region, (iii) the strands are exchanged.
