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.

G5 domain. This domain is found in a wide range of extracellular proteins. It is found tandemly repeated in up to 8 copies. It is found in the N-terminus of peptidases belonging to the M26 family which cleave human IgA. The domain is also found in proteins involved in metabolism of bacterial cell walls suggesting this domain may have an adhesive function.

Gram-positive signal peptide, YSIRK family. Many surface proteins found in Streptococcus, Staphylococcus, and related lineages share apparently homologous signal sequences. A motif resembling [YF]SIRKxxxGxxS[VIA] appears at the start of the transmembrane domain. The GxxS motif appears perfectly conserved, suggesting a specific function and not just homology. There is a strong correlation between proteins carrying this region at the N-terminus and those carrying the Gram-positive anchor domain with the LPXTG sortase processing site at the C-terminus.
