The proteins that act as enzymes from the given options are Isomerase.

Here's why:

1. Isomerase: This is a type of enzyme that catalyzes the rearrangement of the molecular structure of a particular substance. So, it acts as an enzyme.

2. Insulin: This is a hormone produced in the pancreas. It allows your body to use sugar (glucose) from carbohydrates in the food that you eat for energy or to store glucose for future use. It does not act as an enzyme.

3. Haemoglobin: This is a protein in your red blood cells that carries oxygen from your lungs to the rest of your body. It does not act as an enzyme.

So, from the given options, only Isomerase acts as an enzyme.
