Phospholipase A₂ enzymes in A. labialis venom gland. Alignment of PLA₂ enzymes from A. labialis with A. superbus (Aussup) [5] is shown. Residues that are different from A. superbus PLA₂ are highlighted. The three Trp (W) residues present in the β-wing of the A. labialis PLA₂ enzyme are underlined. Clone 518 which encodes a truncated protein is also shown. The number of clones is shown in italics and the predicted signal peptide using SignalP 3.0 is underlined.
