Fungal Cutinase-Like Hydrolases As Prospective PET-Degrading Enzymes: An In Silico Analysis
AI summary Read the abstract
Scientists used computer modeling to show that certain fungal enzymes have a similar shape and chemical "cutting tools" as a bacterial enzyme already known to break down plastic bottles (PET). This matters because plastic pollution and the microplastics it creates are showing up in our food, water, and even bodies — and finding new enzymes that can break down this waste could lead to better tools for cleaning up plastic before it becomes the tiny particles linked to health concerns. This is still early-stage, computer-based research, so real-world lab testing is needed to confirm these fungal enzymes actually work in practice.
The accumulation of polyethylene terephthalate (PET) waste and microplastics generated from the waste has increased alarmingly, and mandates the need for sustainable biodegradation strategies. The bacterial PETase enzyme from Ideonella sakaiensis has been studied exclusively for PET biodegradation, along with similar enzymes from other bacterial sources; however, fungal polyester-degrading hydrolases remain underexplored. Therefore, this study investigated the structural and functional similarity between Ideonella sakaiensis PETase and fungal cutinase-like hydrolases employing computational bioinformatics approaches. A fungal hydrolase sequence obtained from UniProtKB was analyzed using BLASTp, multiple sequence alignment, phylogenetic analysis, and structural comparison tools. Conserved catalytic motifs and Ser–His–Asp/Glu catalytic triads were identified among bacterial PETase and fungal enzymes. Functional domain analysis through InterPro Scan confirmed the presence of conserved α/β hydrolase domains. Furthermore, Structural superimposition using UCSF ChimeraX revealed conservation of the core α/β hydrolase architecture with a low RMSD value despite divergence in loop regions. The findings suggest that fungal cutinase-like hydrolases possess PETase-associated structural and catalytic characteristics and may play a vital role in future PET biodegradation and microplastic remediation strategies.

Fungal Cutinase-Like Hydrolases As Prospective PET-Degrading Enzymes: An In Silico Analysis
AI summary Read the abstract
Scientists used computer modeling to show that certain fungal enzymes have a similar shape and chemical "toolkit" as bacteria already known to break down plastic bottles (PET plastic). This matters because plastic waste breaks down into microplastics that are showing up in our food, water, and even our bodies—so finding more natural ways to break down this plastic could eventually help reduce our exposure to it. Note that this is an early-stage computer analysis, not a lab test, so real-world proof that these fungal enzymes actually degrade plastic still needs to be confirmed through experiments.

Fungal Enzymes as Catalytic Tools for Polyethylene Terephthalate (PET) Degradation
AI summary Read the abstract
This review examines the potential of fungal enzymes, including esterases, lipases, and cutinases, to break down polyethylene terephthalate (PET) plastic waste. Researchers surveyed the literature on how these biocatalysts work and their effectiveness compared to more widely studied bacterial enzymes. The study suggests that fungal enzymes offer a promising and underexplored avenue for developing eco-friendly PET degradation technologies.
Insights into the Transcriptomic Response of Two Aspergillus Fungi Growing in the Presence of Microplastics of Polyethylene Terephthalate Residues Unveil the Presence of Fungal Machinery for Possible PET Bioconversion into High-Value Chemicals
AI summary Read the abstract
Scientists discovered that two types of common fungi can break down plastic particles (specifically PET plastic used in bottles) and potentially turn them into useful chemicals. The fungi produced special enzymes that could eat away small amounts of the plastic over two weeks, suggesting these microorganisms might one day help clean up plastic pollution in our environment. This matters because microplastics are everywhere in our food and water, so finding natural ways to break them down could help reduce our exposure to these tiny plastic particles.
