Fold: Double-stranded beta-helix [51181]
one turn of helix is made by two pairs of antiparallel strands linked with short turns has appearance of a sandwich of distinct architecture and jelly-roll topology
Family: Type I phosphomannose isomerase [51191]
Share a common two-domain fold with the 7S protein; there is a metal-binding site in the N-terminal domain similar to the metal-binding site of germin
Protein: Mannose-6-phosphate isomerase ManA [101987]
