AAA family ATPase
RecF/RecN/SMC N terminal domain
This domain is found at the N terminus of SMC proteins. The SMC (structural maintenance of chromosomes) superfamily proteins have ATP-binding domains at the N- and C-termini, and two extended coiled-coil domains separated by a hinge in the middle. The eukaryotic SMC proteins form two kind of heterodimers: the SMC1/SMC3 and the SMC2/SMC4 types. These heterodimers constitute an essential part of higher order complexes, which are involved in chromatin and DNA dynamics [1]. This family also includes the RecF and RecN proteins that are involved in DNA metabolism and recombination. [1]. 10429180.

DNA repair protein RecN
DNA repair protein RecN may be involved in recombinational repair of damaged DNA
All proteins in this family for which functions are known are ATP binding proteins involved in the initiation of recombination and recombinational repair.
