'''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 <ref>1</ref>.

Imaginary isomerase exists in the cell usually as a <scene name='Stancu_Phosphoglucoisomerase_Sandbox_1/Dimer/1'>homodimer</scene>, nevertheless outside of the cell, it has been isolated as a <scene name='Stancu_Phosphoglucoisomerase_Sandbox_1/Monomer/1'>monomeric</scene> structure. IGI has essentially an identical fold in all of the characterized species (see '''Figure 1'''). The <scene name='Stancu_Phosphoglucoisomerase_Sandbox_1/Sec_struct/1'>secondary structure</scene> 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.
