Table 1.
Averages and standard deviations of significantly different toxin abundances and specific activities between northern (n = 108) and southern phenotypes (n = 38)
| Northern phenotype | Southern phenotype | |
|---|---|---|
| Percent myotoxin | 42 (7.2) | 14 (5.3) |
| Percent SVMP | 10.6 (3.3) | 37.8 (7.8) |
| SVMP activity | 0.34 (0.14) | 0.98 (0.19) |
| Kall-SVSP activity | 856 (563) | 1481 (698) |
| Thr-SVSP activity | 1262 (471) | 1681 (464) |
Abbreviations: SVMP snake venom metalloproteases, Kall-SVSP Kallikrein-like snake venom serine protease, Thr-SVSP thrombin-like snake venom serine protease. SVMP activity is expressed as ΔA342nm/min/mg venom protein, and Kall-SVSP and Thr-SVSP activities are expressed as nanomoles product produced/min/mg venom
