Challenges in distinguishing functional proteins from polyproteins in databases: implications for drug discovery

Area of Science:

• Molecular Biology
• Drug Discovery
• Bioinformatics

Background:

• Current biological databases often conflate polyproteins with their mature functional products.
• This ambiguity presents significant challenges in data retrieval and analysis.
• The issue is exemplified by research into severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) main protease inhibitors.

Purpose of the Study:

• To highlight the critical issue of combined polyprotein and functional product entries in biological databases.
• To emphasize the negative impact on data retrieval accuracy and drug discovery processes.
• To advocate for improved database management practices in scientific research.

Main Methods:

• This is an opinion article, thus no specific experimental methods were employed.
• Analysis of existing database structures and their implications for molecular biology.
• Case study focusing on SARS-CoV-2 main protease inhibitor discovery.

Main Results:

• Combined entries lead to data retrieval errors and hinder the identification of precise molecular targets.
• The lack of clear distinction impedes the development of effective targeted therapies.
• Scientific progress is slowed due to inefficient data accessibility.

Conclusions:

• There is an urgent need for standardized and improved database practices in molecular biology.
• Clearer data organization is essential for accelerating drug discovery and therapeutic development.
• Lessons learned from the SARS-CoV-2 pandemic underscore the importance of robust scientific infrastructure for global health security.
