[https://www.uniprot.org/uniprot/OXLA_BOTAT OXLA_BOTAT] Catalyzes an oxidative deamination of predominantly hydrophobic and aromatic L-amino acids, thus producing hydrogen peroxide that may contribute to the diverse toxic effects of this enzyme (PubMed:18804547). Shows high catalytic activity against L-Met, L-Leu, L-Phe, L-Trp, L-Tyr, L-Ile (PubMed:18804547). Shows no or weak activity on L-Cys, L-Val, L-Gln, L-Thr, L-Ser, L-Lys, L-Arg, L-Asn, L-Glu, L-Gly, L-Pro, L-Asp and L-His (PubMed:18804547). Induces platelet aggregation in platelet-rich plasma, probably due to hydrogen peroxide production, since catalase inhibits aggregation effect (PubMed:18804547). Induces moderate mouse paw edema (PubMed:18804547). Induces apoptosis and shows cytotoxicity against several cancer cell lines, which is inhibited by catalase (PubMed:18804547, PubMed:21300133). Shows hemolytic activity and antibacterial activities against both Gram-positive and Gram-negative bacteria (PubMed:21300133). Has parasiticidal activities against both trypanosomes and leishmania, as a result of enzyme-catalyzed hydrogen peroxide production (PubMed:21300133). Unlike other snake venom L-amino acid oxidases, does not induce hemorrhage (with 50 ug of enzyme) (PubMed:18804547).<ref>PMID:18804547</ref> <ref>PMID:21300133</ref> | |||
