Functional insights into the nitrogenase-like enzyme superfamily

Area of Science:

• Biochemistry
• Enzymology
• Metalloenzymes

Background:

• Nitrogenases are vital enzymes converting atmospheric nitrogen to ammonia, essential for life.
• Nitrogenase-like enzymes evolved from ancestral forms, exhibiting diverse functions.
• These enzymes are involved in processes like bacteriochlorophyll and cofactor F430 biosynthesis.

Purpose of the Study:

• To explore the structural and functional diversity of the nitrogen fixation-like enzyme superfamily.
• To investigate the potential of these enzymes for producing chemical building blocks.

Main Methods:

• Structural analysis of nitrogenase-like enzymes.
• Functional characterization of enzyme activities.
• Exploration of evolutionary relationships within the superfamily.

Main Results:
