- At the present, no secreted phospholipase A2 (sPLA2) from soybean (Glycine max) was investigated in detail. In this work we identified five sequences of putative secreted sPLA2 from soybean after a BLAST search in G. max database. Sequence analysis showed a conserved PA2c domain bearing the Ca2+ binding loop and the active site motif. All the five mature proteins contain 12 cysteine residues, which are commonly conserved in plant sPLA2s. We propose a phylogenetic tree based on sequence alignment of reported plant sPLA2s including the novel enzymes from G. max. According to PLA2 superfamily, two of G. max sPLA2s are grouped as XIA and the rest of sequences as XIB, on the basis of differences found in their molecular weights and deviating sequences especially in the N- and C-terminal regions of the isoenzymes. Furthermore, we report the cloning, expression and purification of one of the putative isoenzyme denoted as GmsPLA2-XIA-1. We demonstrate that this mature sPLA 2 of 114 residues had PLA2 activity on Triton:phospholipid mixed micelles and determine the kinetic parameters for this system. We generate a model based on the known crystal structure of sPLA2 from rice (isoform II), giving first insights into the three-dimensional structure of folded GmsPLA2-XIA-1. Besides describing the spatial arrangement of highly conserved pair HIS-49/ASP-50 and the Ca+2 loop domains, we propose the putative amino acids involved in the interfacial recognition surface. Additionally, molecular dynamics simulations indicate that calcium ion, besides its key function in the catalytic cycle, plays an important role in the overall stability of GmsPLA2-XIA-1 structure. © 2012 Elsevier Masson SAS.
