This domain is found in Mannose-6-phosphate isomerase from Archaeoglobus fulgidus (MPI) and similar bacterial sequences. This enzyme catalyses the interconversion of mannose 6-phosphate and fructose 6-phosphate [1,2]. This entry represents the C-terminal domain, which is found associated with PFam:PF20511. This domain shows an all-beta structure.
