This domain was first characterised as the C-terminal domain of Pab87 serine protease from Pyrococcus abyssi [1]. The domain is reported to play a crucial role in Pab87 octamerisation and active site compartmentalisation. Its up-and-down 8-stranded beta-barrel 3D structure is reminiscent of the one found in lipocalins.	Domain
