Protein “A. superbus venom factor 1”, present in the snake Austrelaps Superbus venom, which are harmful to the complementary immunity system, is analogous to the amino acid sequences found in SARS-CoV2. Cesar Fernandes Geraldes1 (Bachelor of Quality in Life - Mackenzie Presbyterian University and Civil Geotechnical Engineer - Uninove).1 1 Studying Post-Graduation in Data Science at Uninove, São Paulo, Brazil Correspondence: [email protected] Abstract The study crossed the amino acids present in SARS-CoV-2, with the protein “A. Superbus venom factor 1” from the Lowland copperhead snake “Austrelaps Superbus”. The alignment of the sequences of pairs took place through matrix algorithms in high performance processing, by UGene software in terms of GNU. The “A. Superbus venom factor 1”, present in the snake Austrelaps Superbus venom, which are harmful to the complementary immunity system, is analogous to the amino acid sequences found in SARS-CoV2. The result found was of several sequences of amino acids with harmful potential, the most relevant being represented by the letters "LYID", "TAYA" and "NTLT". 1 Introduction As described on Wikipedia in the English version the lowland copperhead or lowlands copperhead Austrelaps superbus is a venomous snake species in the family Elapidae, found in southeastern Australia and Tasmania. It is commonly referred to as the copperhead. The complement system is a fundamental part of innate immunity and contributes to the removal of immune complexes and the activation of inflammatory processes. These proteins represent a fast and efficient means of protecting the host against invading microorganisms. Associations between complement and disease are observed in situations of complement deficiency, abnormalities in complement regulation and inflammation.2 Data science, through the use of computational algorithms and databases, has been a great ally in the development of new knowledge. Bioinformatics has the characteristic of moving between inter- disciplines, as in the present study between the exact and biological disciplines. The health area could not be left out. In such a crucial moment for humanity, where we were affected by a disease spread in a pandemic in global proportions, and the use of computer technologies has added speed and precision to the development of solutions. The objective of this study is to identify possible sequences of amino acids with potential harmful to humans, present in SARS-CoV-2. In an analysis by similarity of the sequencing of amino acids with agents presented nature. The snake chosen from the family chosen for analysis was the Austrelaps superbus, Lowland copperhead snake. Protein “A. superbus venom factor 1”. 1. Do amino acid sequences potentially harmful to the complement system linked to immunity in SARS-CoV-2? Are such venomous animals as venomous as the snake? Recent facts linked to the origin of SARS-CoV-2, led to the question whether there were elements that are natural agents of venomous animals, such as the amino acid sequence of snake venom or adjunct components in SARS-CoV-2. And its potential harmfulness to the immune complement system. 1.1 Protein “A. superbus venom factor 1” A. lowland copperhead, Austrelaps superbus The cobra venom factor, CVF is an uncommon component of the venom of many elapid snakes. Although CVF occurs in the poison, it is not a toxin, but a protein component of the venom that facilitates the entry of toxic components of the poison into the bloodstream by inducing activation of the complement at the site of poisoning. 3 These proteins act by activating, inhibiting or mimicking proteins in this system. They are found mainly in venoms of snakes and spiders. 3 Protein involved in the localized protective response to tissue damage, microbial infection or the presence of foreign matter. It is characterized by edema, redness, heat and pain and involves a complex series of events, including vascular changes and blood cell accumulation, such as neutrophil leukocytes and mononuclear phagocytes, at the site of the lesion. 4 2 2.

It is used for nucleotide and protein sequences. ClustalW is a command line version of the program 5 Regarding ClustalW: “The sensitivity of the commonly used progressive multiple sequence alignment method has been greatly improved for the alignment of divergent protein sequences. Firstly, individual weights are assigned to each sequence in a partial alignment in order to down-weight near-duplicate sequences and up-weight the most divergent ones. Secondly, amino acid substitution matrices are varied at different alignment stages according to the divergence of the sequences to be aligned. Thirdly, residue-specific gap penalties and locally reduced gap penalties in hydrophilic regions encourage new gaps in potential loop regions rather than regular secondary structure. Fourthly, positions in early alignments where gaps have been opened receive locally reduced gap penalties to encourage the opening up of new gaps at these positions. These modifications are incorporated into a new program, CLUSTAL W which is freely available.” 6 Alignment with original MUSCLE package is the ability to align only part of the model. 5When the column range item is selected, the region of the specified columns is passed only to the MUSCLE alignment mechanism. The resulting alignment is inserted into the original.5,7 3. Results: The excerpts presented in the figures below are the most relevant, given the study. In the first line “A.

Discussion Improper or excessive activation of the complement can lead to harmful consequences due to severe inflammatory tissue destruction. Clinical and experimental evidence highlights the role of complement in the pathogenesis of numerous inflammatory diseases, which include not only immune-complex, and autoimmune diseases, but also organ failure following sepsis, multiple traumas and burns.7 Complement-activating protein in snake venom. The “A. superbus venom factor 1” interferes with the complement system.3 The possibility that the amino acid sequence may have been inserted in SARS-CoV-2 is not ruled out, even by publications 1,8,. Nor does it rule out the possibility that it is something natural. Further studies are needed. 5. Conclusion Therefore, the “A. superbus venom factor”, present in the Cobra Austrelaps Superbus venom, which are harmful to the complementary immunity system, is analogous to the amino acid sequences found in SARS-CoV2. The study demonstrated the strings "LYID", "TAYA" and "NTLT", with more relevance to the study. The study was restricted
