Here, we show the sequence homologies between two recently
identified mammalian helicases, namelySUVi andBACH1.
These two genes also share strong homologies with other members
of the RecQ family.
On the basis of published data and sequence analysis we suggest that SUVi/BACH1 may represent a
novel subfamily of mammalian helicases, functioning in the processing of lesions induced by different genotoxic agents.
