While enzymes can exhibit varying degrees of specificity, enzymes that only catalyze a single type of reaction are considered highly specific. This means they have a very narrow range of substrates and reactions they can work on.
Here are some other terms related to enzyme specificity:
* Absolute specificity: The enzyme only reacts with one specific substrate.
* Group specificity: The enzyme reacts with a group of structurally similar substrates.
* Stereochemical specificity: The enzyme reacts with a specific stereoisomer of a substrate.
However, "highly specific" is the most common term used to describe enzymes that catalyze only one type of reaction.
