And to demonstrate how this is actually used and how it works inside ourselves, let's take a look at a specific type of allosteric enzyme known as aspersate transcarbomoly. So in this lecture and the next several lectures, we're going to focus on how this enzyme actually works and how it is regulated. So let's begin by discussing the reaction that this enzyme actually catalyzes. So that the reaction is shown on the board. We have carboyl phosphate that reacts with aspartate. So these are the two substrate molecules to the aspartate transcarbomolase and this catalyzes the conversion of these molecules into these two products.
