Cartoon and topology plot of StmPr1 47 kDa. (a) The secondary structure, predicted using AlphaFold3, is indicated in different colors. Loops are depicted in green, sheets in yellow and helices in red. (b) The topology plot is depicted in the same color scheme and highlights the Ca-binding site and catalytic triad. (c) Top view of the secondary structure indicated in the same colors to show secondary structure features missing in a). The two disulfide bridges (Cys93-Cys141, 1 and Cys183 - Cys220, 3) and the catalytic triad (2) are highlighted individual.
