Proteolytic cleavage of stingray phospholipase A2: Isolation and biochemical characterization of an active N-terminal form

Table 3 Sequences comparison of protein fragments isolated after chymotryptic and tryptic proteolysis of SPLA2 with PPLA2

For comparison, bold, underlined, and italic symbols of residues indicate identical, homologous, and different amino acids, respectively. The Ca²⁺ loop (C27-G32) is bold shaded. Stars indicate the amino-acid residues of the catalytic triad. The arrows indicate the tryptic or chymotryptic cleavage site of SPLA2.
