Protein Family Models

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. Paper describing PDB structure 2wfp. [1]. 19564693.

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]. [1]. 8612079. The x-ray crystal structure of phosphomannose isomerase from Candida albicans at 1.7 angstrom resolution.

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]. [1]. 8612079.

The names phosphomannose isomerase and mannose-6-phosphate isomerase are synonomous. This family contains two rather deeply branched groups. One group contains an experimentally determined phosphomannose isomerase of Streptococcus mutans as well as three uncharacterized paralogous proteins of Bacillus subtilis, all at more than 50 % identity to each other, plus a more distant homolog from Archaeoglobus fulgidus. The other group contains members from E. coli, budding yeast, Borrelia burgdorferi, etc.
