A	PF20511	Phosphomannose isomerase type I, catalytic domain (PMI_typeI_cat)	Phosphomannose isomerase type I, catalytic domain	This entry represents the catalytic domain of Phosphomannose isomerase type I enzymes (EC 5.3.1.8) which contains a zinc-binding site. It is composed of beta-strands connected by long loops in a jelly roll conformation [1].	Domain
A	PF21621	Mannose-6-phosphate isomerase, cupin domain (MPI_cupin_dom)	Mannose-6-phosphate isomerase, cupin domain	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-term ...	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.	Domain
A	PF20512	Phosphomannose isomerase type I, helical insertion domain (PMI_typeI_hel)	Phosphomannose isomerase type I, helical insertion domain	This entry represents the alpha-helical insertion domain of Phosphomannose isomerase type I enzymes (EC 5.3.1.8), in which the helices are packed closely, connected by short turns and loops. This domain packs closely against the catalytic domain, int ...	This entry represents the alpha-helical insertion domain of Phosphomannose isomerase type I enzymes (EC 5.3.1.8), in which the helices are packed closely, connected by short turns and loops. This domain packs closely against the catalytic domain, interrupting it [1].	Domain
