Enzymsentre

Enzymsentre is a term occasionally used to describe the functional center of an enzyme where chemical conversion of substrates takes place. In this usage, it designates the region surrounding the catalytic core that directly participates in catalysis, substrate recognition, and regulation. The term is not standard in formal biochemistry; more common descriptors include active site, catalytic center, and binding pocket.

Origin and usage: The term has appeared in informal discussions and some non‑peer‑reviewed sources, but it is not widely adopted in peer‑reviewed literature. In formal contexts, scientists usually refer to the active site, catalytic center, or binding pocket to describe the same concepts.

Composition: The enzymsentre comprises catalytic residues, cofactors or prosthetic groups, metal ions, and sometimes nearby residues that shape the pocket and stabilize transition states. It can extend beyond the strictly defined active site to include networks involved in substrate channeling, dynamics, or allostery.

Functions and implications: Recognizing the enzymsentre concept highlights how local structure and dynamics govern reaction rates and specificity. It is relevant for enzyme design, inhibitor development, and understanding allosteric regulation. For drug discovery, targeting the enzymsentre implies focusing on the catalytic region and its surrounding networks.
