T4 endonuclease V exists in solution as a monomer and binds to target sites as a monomer.

Abstract

Endonuclease V, a N-glycosylase/lyase from T4 bacteriophage that initiates the repair of cyclobutane pyrimidine dimers in DNA, has been reported to form a monomer-dimer equilibrium in solution [Nickell and Lloyd (1991) Biochemistry 30, 8638], although the enzyme has only been crystallized in the absence of substrate as a monomer [Morikawa et al. (1992… (More)
