RecX, first three-helix domain
This entry represents the first three-helix domain (HTH-like) found in RecX family of proteins. RecX functions as a regulator of DNA recombination and repair pathways in bacterial cells [1]. RecX protein is known to inhibit the activity of RecA protein in DNA recombination [2,3]. [1]. 23284295. RecX facilitates homologous recombination by modulating RecA activities.
