This is the insert domain found in DNA gyrase B subunit proteins. Studies indicate that the insert has two functions, acting as a steric buttress to pre-configure the primary DNA-binding site, and serving as a relay that may help coordinate communication between different functional domains [1].

This entry represents the N-terminal section of the 'Toprim hook' as described in [1], which is localised between the Toprim (Pfam:PF01751) and the insert (Pfam:PF18053) domains [1-3]. The C-terminal section of the hook is included in (Pfam:PF00986). The hook is flexible towards the Toprim domain.	Domain
