Functional characterization and FTIR-based 3D modeling of full length and truncated forms of Scorpio maurus venom phospholipase A.

•High activity of Sm-PLGV results from the excision of the penta-peptide.•The resulting short chain is important for enzymatic activity.•Hemolytic power is related to phospholipase activity.•FTIR-assisted 3D modeling showed the role of the short chain enzymatic activity.
