XGTPase has a conserved sequence, 85-IVIDDLVDTG-94, which is called the PRib-PP (5-phospho-a-D-ribosyl-1-pyrophosphate) binding site<ref name="Vos"/>. This binding site features two adjacent acidic residues, which are surrounded by hydrophobic residues<ref name="Vos"/>.

This binding site features two adjacent acidic residues, which are surrounded by hydrophobic residues<ref name="Vos"/>. There is a five-stranded b-sheet surrounded by three or four a-helices that creates a conserved structural core containing the PRib-PP binding site<ref name="Vos"/>. Another region of the sequence in XGTPase forms a lobe, which is involved in substrate recognition<ref name="Vos"/>. | ||
