Comparative pairwise alignment of the expansin/GH45 domain of L. sulphureus with two basidiomycetes GH45-EGs (G. trabeum and P. chrysosporium), with one ascomycete GH45-EG (H. jecorina) and with one CBM1-swollenin from H. jecorina. The biochemically characterized GH45-EG from P. chrysosporium is indicated in blue for the catalytic amino acids (N92 and D114) and in pink for the neighboring amino acids involved in the proton transfer network
