P0DH44 · XERS_STRP3

Function

function

Site-specific tyrosine recombinase, which acts by catalyzing the cutting and rejoining of the recombining DNA molecules. Essential to convert dimers of the bacterial chromosome into monomers to permit their segregation at cell division.

Activity regulation

FtsK is required for recombination.
