New #cryoET structure from LSI Exeter colleagues Matthew Gaines et al. Bertram Daum lab, this time of the enigmatic #archaeal filament called 'thread'.

What I find cool about this work is that first they had the structure, then found the sequence based on glycosylation sites and bulky residues.
This #protein was also so ultra-stable, that resisted trypsinisation, so mass spec was not an option to identify it.
