This domain is present in bacterial ureases and corresponds to the gap region between the C-terminus of the beta-chain Urease beta subunit Pfam:PF00699 and the N-terminus of the alpha-chain Urease alpha-subunit, N-terminal domain Pfam:PF00449 [1]. It is suggested that this region is required for the stability of the putative transmembrane beta-barrel, and might be the reason for bacterial urease (B. pasteurii) not being lethal to insects [2].
The N-terminal domain is a composite domain and plays a major trimer stabilising role by contacting the catalytic domain of the symmetry related alpha-subunit.
