enzymem

Enzymem is a term used in some speculative discussions to describe a hypothetical class of biological catalysts that extend the traditional definition of enzymes. The name combines "enzyme" with "memory" or "meme," signaling an imagined capability to carry information or influence cellular states beyond simple chemical transformation. It is not an established term in mainstream biochemistry, and there is no consensus that such molecules exist in nature.

In these theoretical frameworks, an enzymem would perform catalytic reactions while also acting as an information-bearing element. Proponents imagine it could alter regulatory networks, influence signaling pathways, or template state changes in response to substrate context. The idea is often discussed as a thought experiment about how metabolism and cellular information processing might intersect.

Proposed features include dual functional outputs, context-dependent activity, and the potential for long-lived conformational states that persist after catalysis. Some models describe enzymems as capable of feedback to gene regulation or chromatin states, though such claims remain speculative and unverified.

Critics argue that the concept blends metaphor with testable biology in ways that risk misinterpretation of enzyme function. Without clear operational definitions and experimental evidence, enzymem remains a hypothetical construct rather than a recognized biological entity.
