Cysteine Residues Are Required for the Sliding Clamp-Dependent Endonuclease Activity of Neisseria gonorrhoeae MutL.
BACKGROUND Neisseria gonorrhoeae is a human pathogen that causes gonorrhea and employs a methylation-independent mismatch repair (MMR) pathway to regulate genomic stability and pilin antigenic variation. A key effector of this pathway, MutL, possesses ATPase, DNA-binding, and endonuclease activities, yet the molecular...
