Figure 3. Four conserved motifs of S. alfredii GELPs.

The four consensus blocks I, II, III and V represent the conserved motifs in the amino acid sequences of the GDSL family, and are numbered based on their location from the N to C terminal. Triangles represent the conserved catalytic residues in conserved domains. Ser (S), Gly (G), Asn (N) and His (H) are conserved residues.
