By following these pages the reader will investigate five snake venom PLA-2 enzymes that have been subjected to X-ray
crystallographic analysis and have coordinate files lodged with the Brookhaven Protein Data Bank (PDB). These five PLA-2
sequences are derived from venoms of 3 viperid/crotalid snakes of the Americas. Sequence similarities and differences are examined using selected database and
alignment tools and the 3-dimensional structures may be visualised using the Rasmol molecular viewer program to see the
extent to which sequence information is mirrored in secondary and tertiary structural features. |
