Overall view of selected AA10 structures and the closest non-LPMO structural relative. The structurally common central β-cores are coloured yellow, while distinct structural elements are coloured differently for each structure. (a) SmAA10_A with the (`budded') helical insert in cyan and elements differing compared with JdAA10_A indicated in red. (b) JdAA10_A with the helical insert in blue. (c) The closest non-LPMO structural homologue (the MG2 domain of human α2-­macroglobulin; PDB entry 2p9r) with a small helical segment in green. (d) Fusolin (Melolontha melolontha entomopoxvirus; PDB entry 4ow5) with a number of helical segments in magenta.
