Structure sequence alignment of Arabidopsis PAEs with a human palmitoleoyl-protein carboxylesterase. The PAE sequence retrieved from Uniprot was structure-aligned with one human Notum (PDB code: 4UYU chain A) using Expresso [73] and rendered using ESPript3 [72]. Conserved residues are masked in red (absolutely conserved) or yellow. The catalytic triad in 4UYU is indicated by a red star. Secondary structure elements of 4UYU_A are shown at the top. α, β, n and T represent α-helix, β-strand, 3₁₀ helix and β-turn, respectively
