Enzymers

Enzymers is a term used to describe enzyme-based catalysts involved in polymer-related reactions or enzymes engineered specifically for polymer synthesis and modification. It is not an established taxonomic category in mainstream biochemistry. In most scientific contexts, reactions that would be described as enzymers are discussed using standard classifications such as polymerases, ligases, hydrolases, or transferases, or described as biocatalytic polymerization or depolymerization.

Origin and scope: The coinage appears in speculative biology, early-stage biotech literature, and industry discussions to emphasize an enzyme’s ability to form polymers. The term can refer to natural enzymes that participate in polymer assembly or to engineered variants optimized for chain growth, branching, or degradation. It does not imply a single, unified mechanism.

Mechanisms: Enzyme-catalyzed polymerization and depolymerization rely on substrate binding in an active site, transition-state stabilization, and often processivity. When used to build polymers, Enzymers may add monomer units sequentially; when modifying polymers, they may alter end groups or introduce functional moieties. Kinetic behavior generally follows Michaelis–Menten characteristics, with processivity and substrate inhibition shaping outcomes in polymer contexts.

Applications: In industrial biotechnology, enzyme-catalyzed polymer synthesis can offer milder conditions and higher selectivity than many chemical methods. Potential applications include biodegradable plastics, surface coatings, and medical polymers. Engineering aims to improve stability, substrate scope, and control over polymer length and branching. Limitations include enzyme stability, product inhibition, and substrate availability.
