Figure 2
Domain architecture and structural features of Fsc1 FAS1 domains. (a) Representative β-sandwich fold of Fsc1. A detailed view of FAS1-2 and FAS1-3, with secondary-structure elements annotated to highlight the β-strands and α-helices characteristic of the fasciclin fold. (b) Surface representation of Fsc1, highlighting a deep central groove present in FAS1-4 (residues Thr518–Asp532) shown in red. (c) FAS1 domains of human TGFBI (PDB entry 5nv6), featuring expanded β-sheets and α-helices (six to seven elements) compared with the five or six β-sheet/α-helix elements typically observed in most fasciclin proteins. |
