L-fucose isomerase, N-terminal-1 (IPR012888)

Short name: Fucose_iso_N1

Overlapping homologous superfamilies

Domain relationships



Proteins containing this domain are similar to L-fucose isomerase expressed by Escherichia coli (P11552, EC: This enzyme corresponds to glucose-6-phosphate isomerase in glycolysis, and converts an aldo-hexose to a ketose to prepare it for aldol cleavage. The enzyme is a hexamer, with each subunit being wedge-shaped and composed of three domains. Both domains 1 and 2 contain central parallel beta-sheets with surrounding alpha helices. Domain 1 demonstrates the beta-alpha-beta-alpha-beta Rossman fold. The active centre is shared between pairs of subunits related along the molecular three-fold axis, with domains 2 and 3 from one subunit providing most of the substrate-contacting residues, and domain 1 from the adjacent subunit contributing some other residues [PMID: 9367760].
