The cytochrome P450 engineering database: Integration of biochemical properties

Area of Science:

• Biochemistry
• Structural Biology
• Bioinformatics

Background:

• Cytochrome P450 monooxygenases (CYPs) are crucial enzymes in drug development with significant biotechnological potential.
• Despite sequence diversity, CYPs share a common structural fold, necessitating systematic comparison tools.
• The Cytochrome P450 Engineering Database (CYPED) was developed for comprehensive analysis of CYP sequences and structures.

Purpose of the Study:

• To present an enhanced version of the CYPED with updated data and functionalities.
• To improve the integration of sequence, structure, and biochemical information for CYPs.
• To provide a valuable resource for researchers in drug development and biotechnology.

Main Methods:

• The updated CYPED includes data for 8613 sequences and 47 structures, adhering to Nelson's classification rules.
• CYPED was linked to the Cytochrome P450 Knowledgebase (CPK) for biochemical data on substrates and inhibitors.
• A sequence similarity metric was developed to link CYPED and CPK data, overcoming model inconsistencies.
• Annotation was enhanced with predictions of conserved secondary structures and effects of single nucleotide polymorphisms.

Main Results:

• The new CYPED version contains extensive data on CYP sequences and structures.
• Integration with CPK provides biochemical context for CYP proteins.
• The established metric effectively links disparate data sources, ensuring data consistency.
• Enhanced annotation provides deeper insights into structural and functional aspects of CYPs.

Conclusions:

• The online CYPED is a valuable, accessible tool for analyzing CYP sequences, structures, and biochemical properties.
• This resource supports research in drug development, enzyme engineering, and understanding CYP function.
• The extensible data model allows for continuous enhancement of CYPED's capabilities.
