Fig. 2: Atomic model of the M. villosus archaellum filament.
From: An archaellum filament composed of two alternating subunits
a–c Atomic model of the archaellum filament with glycosylation in side view (a) and cross-section parallel (b) and perpendicular (c) to the filament’s long axis. ArlB1 is in cyan, ArlB2 in sand, and glycosylation in orange. Scale bar, 50 Å. d, e Atomic models of ArlB1 (d) ArlB2 (e) in ribbon representation and cyan-white-maroon colour scheme (N-terminus, cyan; C-terminus, maroon). The arrow in e highlights the “glycosylation loop”. f Superposition of the ArlB1 (cyan) and ArlB2 (sand) head domain with the metal-binding site and “glycosylation loop” highlighted. Scale bar in d, e and f, 10 Å.
