DR2241 is found in D. radiodurans. The middle domain has four alpha-helices (alpha7-alpha10) in contact with the N-terminal domains and C-terminal domain and five anti-parallel beta-strands with strand order 12354 at the outer side of one monomer. The middle domain, as well as the C-terminal domain, are heavily involved in the tetramer stabilisation [1].

This domain has been shown to harbour the sequence motifs CxxC and CxxxC which bind a [4Fe-4S] iron-sulphur cluster. Together with the preceding domain, it is heavily involved in the tetramer formation [1].
