CD spectra and homology model of native SWO1. a Smoothed CD spectrum of native SWO1 in 50 mM sodium acetate buffer, pH 5.0, at room temperature. For further details of the measurement, see the “Methods” section. b The automated protein structure homology-modeling server Phyre2 was used to predict the protein structure of SWO1 (UniProt ID: Q9P8D0). The distinct domains are colored as follows: family 1 CBM (blue); linker/Fn-III-like domain (orange); GH45 domain (red); expansin-like CBM (green). c A structural overlay of the modeled expansin-like domain from SWO1 with EXLX1 from B. subtilis (PDB ID: 4FG2) was made to allow visual comparison. The distinct domains are colored as follows: EXLX1 (blue); GH45 domain (red); expansin-like CBM (green). Overall, 87 % of the input sequence was modeled at >90 % confidence, and 61 residues were modeled ab initio. The depicted model was used to calculate the percentage of secondary structure elements
