Fungal Enzymes Have Converted Prenyl Groups
Researchers identified two enzymes capable of transforming five-carbon structures into four-carbon motifs.
Updated on Sept. 28, 2026 in Chemistry
Scientists have identified two fungal cytochrome P450 enzymes that facilitate the chemical conversion of prenyl groups. This research-stage finding details how these enzymes perform oxidative C(sp)-demethylation to modify molecular precursors.
Why it matters
The discovery illuminates a biological mechanism for creating specialized chemical motifs that are otherwise difficult to synthesize. This process allows for the transformation of five-carbon prenyl groups into four-carbon allene or alkyne motifs.
The enzymes utilize oxidative C(sp)-demethylation to shorten five-carbon prenyl groups into four-carbon allene or alkyne motifs. This specific chemical transformation effectively removes a single carbon atom to achieve the resulting structure.
The players
Nature Chemical Biology
A monthly peer-reviewed scientific journal that covers research at the interface of chemistry and biology.
The details
Cytochrome P450 enzymes are a large family of proteins that typically catalyze the oxidation of organic substances. In this process, the enzymes facilitate a specific oxidative C(sp)-demethylation—a reaction that removes a methyl group from an sp-hybridized carbon atom. By acting on five-carbon prenyl groups, which are common building blocks in biological systems, the enzymes successfully rearrange the molecular scaffold into four-carbon allene or alkyne motifs.

The Tech Race
This study follows a pattern set by the field of biocatalysis, which aims to leverage protein-mediated reactions to achieve precise chemical transformations that are often challenging for traditional synthetic methods. Researchers continue to compete to isolate naturally occurring enzymes capable of replacing expensive or toxic industrial catalysts.
This research is currently in the experimental stage and does not yet apply to commercial or consumer products. Future applications may include biological routes to synthesize complex chemical precursors for the pharmaceutical or materials science industries.
The takeaway
The study demonstrates that fungal enzymes can perform precise chemical pruning of prenyl groups via oxidative demethylation. Watch for subsequent papers detailing the substrate scope of these enzymes to determine their potential in synthetic chemistry pipelines.
