== Function ==
[https://www.uniprot.org/uniprot/PA2B3_BUNCE PA2B3_BUNCE] Snake venom phospholipase A2 (PLA2) that shows anticoagulant and neurotoxic activities. PLA2 catalyzes the calcium-dependent hydrolysis of the 2-acyl groups in 3-sn-phosphoglycerides (By similarity).

== Publication Abstract from PubMed ==
Reinterpretations of the space-group symmetry are reported for two crystal structures of phospholipase A(2) isoforms (PDB codes 1u4j and 1g2x). The two structures reported in space groups R3 and C2 are isomorphous with a third isoform with space group R32 (PDB code 1fe5). The original structure reports were interpreted in terms of different oligomeric forms of the isoforms, but these conclusions are not supported by the isomorphous structures.
