Alpha-L-fucosidase [Carbohydrate transport and metabolism].

Alpha-L-fucosidase.

Alpha-L-fucosidase. O-Glycosyl hydrolases (EC 3.2.1.-) are a widespread group of enzymes that hydrolyse the glycosidic bond between two or more carbohydrates, or between a carbohydrate and a non-carbohydrate moiety. A classification system for glycosyl hydrolases, based on sequence similarity, has led to the definition of 85 different families. This classification is available on the CAZy (CArbohydrate-Active EnZymes) web site. Because the fold of proteins is better conserved than their sequences, some of the families can be grouped in 'clans'. Family 29 encompasses alpha-L-fucosidases, which is a lysosomal enzyme responsible for hydrolyzing the alpha-1,6-linked fucose joined to the reducing-end N-acetylglucosamine of the carbohydrate moieties of glycoproteins. Deficiency of alpha-L-fucosidase results in the lysosomal storage disease fucosidosis.

Polymerase and Histidinol Phosphatase domain of bacterial polymerase X. The bacterial/archaeal X-family DNA polymerases (PolXs) have a PHP domain at their C-terminus. The bacterial/archaeal PolX core domain and PHP domain interact with each other and together are involved in metal dependent 3'-5' exonuclease activity. The PHP (also called histidinol phosphatase-2/HIS2) domain is associated with several types of DNA polymerases, such as PolIIIA and family X DNA polymerases, stand alone histidinol phosphate phosphatases (HisPPases), and a number of uncharacterized protein families. The PHP domain has four conserved sequence motifs and contains an invariant histidine that is involved in metal ion coordination. PolX is found in all kingdoms, however bacterial PolXs have a completely different domain structure from eukaryotic PolXs. Bacterial PolX has an extended conformation in contrast to the common closed 'right hand' conformation for DNA polymerases. This extended conformation is stabilized by the PHP domain. The PHP domain of PolX is structurally homologous to other members of the PHP family that has a distorted (beta/alpha)7 barrel fold with a trinuclear metal site on the C-terminal side of the barrel.
