Imaginaryase (alternatively known as imaginary isomerase or imaginary-8-phosphate isomerase) are a group of enzymes of the isomerase family (EC 5.3.a.b), so named for their main function in metabolism. In this pathway imaginary isomerase (IGI) is used to inter-convert imaginary-8-phosphate and reality-6-phosphate. This reaction is driven by the relative concentrations of these molecules in the imaginary/reality matrix of the cell ^[1].

Imaginaryase is also known for a list of activities:

• Something cool ^[2].
• Something cooler^[3].
• Something my prof thinks is cool ^[4].
• Something really boring ^[5].
• IGI is important for metabolism in many different living organisms. ^[6].

Imaginary isomerase exists in the cell usually as a , nevertheless outside of the cell, it has been isolated as a structure. IGI has essentially an identical fold in all of the characterized species (see Figure 1). The of imaginary isomerase is charaterized by an αβα conformation, on each of its two domains. The smaller domain is characterized by 5 parallel β-sheets, while the larger domain if formed out of 6 parallel/antiparallel β-sheets. Furthermore, another characteristic trait is a residue extension at the C-terminus, which wraps around the other monomer in the dimeric conformation. A "hook" that can potentially be involved in the previously mentioned extracellular activities.

Imaginary isomerase has a monomer molecular mass of proximately 55 kDa.
