Cyp51. also known as sterol 14α-demethylase, is a key enzyme in the cytochrome P450 superfamily, playing a central role in sterol biosynthesis across eukaryotes. It catalyzes the removal of the 14α-methyl group from lanosterol or eburicol in fungi (yielding ergosterol) or from lanosterol in animals (yielding cholesterol), a critical step in membrane integrity and cellular function. Due to its essential role in fungal ergosterol synthesis, Cyp51 is a primary target for azole-class antifungal drugs, which inhibit enzyme activity by binding to its heme-coordinated active site.
Recombinant Cyp51 proteins are engineered through heterologous expression systems (e.g., *E. coli*, yeast, or insect cells) to study enzyme structure, function, and drug interactions. These systems enable large-scale production of purified protein for biochemical assays, structural analysis (via X-ray crystallography or cryo-EM), and high-throughput drug screening. Fungal Cyp51 variants associated with azole resistance—often due to mutations or overexpression—are particularly studied to decipher resistance mechanisms and design next-generation inhibitors.
In human health, human Cyp51 mutations are linked to developmental disorders, highlighting its physiological importance. Recombinant forms also aid in exploring host-pathogen interactions and species-specific differences in sterol pathways. Beyond biomedicine, plant Cyp51 homologs are investigated for their roles in phytoalexin biosynthesis and stress responses. Overall, recombinant Cyp51 serves as a vital tool for antifungal development, mechanistic enzymology, and understanding sterol-related diseases.
