[Snake Venom L-Amino Acid Oxidases potential biomedical applications]

Area of Science:

• Biochemistry
• Toxicology
• Enzymology

Context:

• L-amino acid oxidases (LAAOs) are flavoenzymes prevalent in snake venoms.
• These enzymes contribute significantly to the toxicity of snake envenomation.
• While enzymatic activity is the primary source of toxicity, alternative mechanisms are under investigation.

Purpose:

• To review the biochemical properties and structural characteristics of snake venom LAAOs.
• To summarize the diverse biological functions and pharmacological effects of these enzymes.
• To elucidate the putative mechanisms of action underlying LAAO activity.

Summary:

• This review consolidates information on snake venom L-amino acid oxidases (LAAOs).
• It covers their biochemical and structural attributes, biological roles (including effects on platelet aggregation, apoptosis, hemorrhage, and cytotoxicity), and proposed mechanisms of action.
• The significant biotechnological potential for developing antimicrobial, antitumor, and antiprotozoan agents is emphasized.

Impact:

• Provides a comprehensive overview of snake venom LAAOs for researchers.
• Highlights the dual nature of LAAOs as toxic agents and therapeutic leads.
• Facilitates further investigation into LAAO mechanisms and biotechnological applications.
