Abstract
Background: Bothrops atrox is known to be the pit viper responsible for
most snakebites and human fatalities in the Amazon region. It can be found
in a wide geographical area including northern South America, the east of
Andes and the Amazon basin. Possibly, due to its wide distribution and
generalist feeding, intraspecific venom variation was reported by previous
proteomics studies. Sex-based and ontogenetic variations on venom
compositions of Bothrops snakes were also subject of
proteomic and peptidomic analysis. However, the venom peptidome of
B. atrox remains unknown. Methods: We conducted a mass spectrometry-based analysis of the venom peptides of
individual male and female specimens combining bottom-up and top-down
approaches. Results: We identified in B. atrox a total of 105 native peptides in
the mass range of 0.4 to 13.9 kDa. Quantitative analysis showed that
phospholipase A2 and bradykinin potentiating peptides were the
most abundant peptide families in both genders, whereas disintegrin levels
were significantly increased in the venoms of females. Known peptides
processed at non-canonical sites and new peptides as the Ba1a, which
contains the SVMP BATXSVMPII1 catalytic site, were also revealed in this
work. Conclusion: The venom peptidomes of male and female specimens of B.
atrox were analyzed by mass spectrometry-based approaches in
this work. The study points to differences in disintegrin levels in the
venoms of females that may result in distinct pathophysiology of
envenomation. Further research is required to explore the potential
biological implications of this finding.
