A Unified Numbering Scheme for Class C β-Lactamases

Area of Science:

• Biochemistry
• Enzymology
• Molecular Biology

Background:

• Class C β-lactamases are crucial enzymes involved in antibiotic resistance.
• Variability in enzyme nomenclature hinders comparative research.

Purpose of the Study:

• To propose and implement a standardized numbering scheme for class C β-lactamases.
• To facilitate clear communication and data comparison in the field.

Main Methods:

• Review of existing β-lactamase nomenclature.
• Development of a consistent numbering system based on sequence alignment and structural features.

Main Results:

• A unified numbering scheme for class C β-lactamases has been established.
• The proposed scheme allows for unambiguous identification of amino acid positions across different enzymes.

Conclusions:

• The standardized numbering scheme enhances the comparison of biochemical and biophysical studies.
• This initiative will improve collaboration and accelerate research on class C β-lactamases.
