5/ We find that sheaths are widespread across ANME-1 archaea. Sequence similarity suggests multiple acquisitions via recent horizontal gene transfers from Methanothrix and Methanospirillum.

1/ Sheaths were first discovered in two archaeal methanogens: Methanospirillum and Methanothrix. They are tube-like surface structures, shared by multiple cells within a filament, which remain largely understudied.

2/ Sheaths are made of SH proteins, organized into rings. SH protein consists of an amyloid domain (facing the interior of the sheath tube) and a “cap” domain. SH proteins of Methanospirillum and Methanothrix have no sequence similarity, so how can we identify sheath in other archaea?

Archaea are weird... in a very cool way! Some species like Methanospirillum hungatei can make an external protein sheath around them. This study in Nat Comms shows more on its structure and biogenesis. It has amyloid fibers! (but ≠ from CsgA/curli)
