An enzyme that catalyzes the hydrolysis of an alpha L-fucoside to yield an alcohol and L-fucose. Deficiency of this enzyme can cause FUCOSIDOSIS. EC 3.2.1.51.
An autosomal recessive lysosomal storage disease caused by a deficiency of ALPHA-L-FUCOSIDASE activity resulting in an accumulation of fucose containing SPHINGOLIPIDS; GLYCOPROTEINS, and mucopolysaccharides (GLYCOSAMINOGLYCANS) in lysosomes. The infantile form (type I) features psychomotor deterioration, MUSCLE SPASTICITY, coarse facial features, growth retardation, skeletal abnormalities, visceromegaly, SEIZURES, recurrent infections, and MACROGLOSSIA, with death occurring in the first decade of life. Juvenile fucosidosis (type II) is the more common variant and features a slowly progressive decline in neurologic function and angiokeratoma corporis diffusum. Type II survival may be through the fourth decade of life. (From Menkes, Textbook of Child Neurology, 5th ed, p87; Am J Med Genet 1991 Jan;38(1):111-31)
An integrin heterodimer widely expressed on cells of hematopoietic origin. CD11A ANTIGEN comprises the alpha chain and the CD18 antigen (ANTIGENS, CD18) the beta chain. Lymphocyte function-associated antigen-1 is a major receptor of T-CELLS; B-CELLS; and GRANULOCYTES. It mediates the leukocyte adhesion reactions underlying cytolytic conjugate formation, helper T-cell interactions, and antibody-dependent killing by NATURAL KILLER CELLS and granulocytes. Intracellular adhesion molecule-1 has been defined as a ligand for lymphocyte function-associated antigen-1.
Cell-surface glycoprotein beta-chains that are non-covalently linked to specific alpha-chains of the CD11 family of leukocyte-adhesion molecules (RECEPTORS, LEUKOCYTE-ADHESION). A defect in the gene encoding CD18 causes LEUKOCYTE-ADHESION DEFICIENCY SYNDROME.
A family of transmembrane glycoproteins (MEMBRANE GLYCOPROTEINS) consisting of noncovalent heterodimers. They interact with a wide variety of ligands including EXTRACELLULAR MATRIX PROTEINS; COMPLEMENT, and other cells, while their intracellular domains interact with the CYTOSKELETON. The integrins consist of at least three identified families: the cytoadhesin receptors(RECEPTORS, CYTOADHESIN), the leukocyte adhesion receptors (RECEPTORS, LEUKOCYTE ADHESION), and the VERY LATE ANTIGEN RECEPTORS. Each family contains a common beta-subunit (INTEGRIN BETA CHAINS) combined with one or more distinct alpha-subunits (INTEGRIN ALPHA CHAINS). These receptors participate in cell-matrix and cell-cell adhesion in many physiologically important processes, including embryological development; HEMOSTASIS; THROMBOSIS; WOUND HEALING; immune and nonimmune defense mechanisms; and oncogenic transformation.
Integrin alpha4beta1 is a FIBRONECTIN and VCAM-1 receptor present on LYMPHOCYTES; MONOCYTES; EOSINOPHILS; NK CELLS and thymocytes. It is involved in both cell-cell and cell- EXTRACELLULAR MATRIX adhesion and plays a role in INFLAMMATION, hematopoietic cell homing and immune function, and has been implicated in skeletal MYOGENESIS; NEURAL CREST migration and proliferation, lymphocyte maturation and morphogenesis of the PLACENTA and HEART.

Endometrial lysosomal enzyme activity in normal cycling endometrium. (1/168)

The objective of this study was to evaluate the possible role of four lysosomal enzymes in endometrial function and remodelling during the normal menstrual cycle by fluorimetric measurement (acid phosphatase, N-acetyl-beta-D-glucosaminidase, alpha-L-fucosidase and alpha-D-mannosidase). A prospective study was conducted of 45 endometrial biopsies obtained from women with normal menstrual cycles. Activity of all four enzymes was identified in human endometrium. Activity of acid phosphatase and N-acetyl-beta-D-glucosaminidase was relatively high, whilst that of alpha-L-fucosidase and alpha-D-mannosidase was low. There was no significant change in the activity of any of the four enzymes from the proliferative to the secretory phase of the cycle. This study suggests that the activity of these enzymes remains constant throughout a major portion of the normal cycle.  (+info)

Characterization of human semen alpha-L-fucosidases. (2/168)

Human semen contains a large amount of alpha-L-fucosidase activity, the great majority of which is found in the seminal fluid. Immunocytochemical studies indicate that a small amount of semen fucosidase activity is present on the sperm plasma membrane, primarily in the posterior head region. Subcellular fractionation studies also indicate that sperm alpha-L-fucosidase is present in the plasma membrane-enriched fraction. Comparative characterization of human seminal fluid and sperm alpha-L-fucosidases indicates that seminal fluid alpha-L-fucosidase has a broad pH optimum curve with a number of near-equal maxima between pH 4.8 and 7.0 while sperm fucosidase has a major optimum between pH 3.4 and 4.0. Isoelectric focusing indicates that seminal fluid alpha-L-fucosidase contains three to six isoforms with isoelectric points (pI) of 5-7 while sperm fucosidase contains two distinct isoforms with pI values of 5. 2 +/- 0.2 and 7.0 +/- 0.2. Western blotting indicates that seminal fluid fucosidase contains a major protein band with a molecular mass ratio (M(r)) of approximately 56 kDa while sperm fucosidase contains a major protein band of approximately 51 kDa. The overall results indicate the presence of a low-abundance, plasma membrane-associated human sperm alpha-L-fucosidase, which is different in its properties from human seminal fluid alpha-L-fucosidase(s), and whose function is not yet known.  (+info)

Fucose in alpha(1-6)-linkage regulates proliferation and histogenesis in reaggregated retinal spheroids of the chick embryo. (3/168)

We have used the lectin from Aleuria aurantia (AAL) which is highly specific for alpha(1-6)-linked fucose, to examine its effect on chicken retinogenesis in a reaggregation culture system. When dispersed cells of the embryonic chick retina are reaggregated to form histotypic retinospheroids, AAL elicits strong inhibition of spheroid growth. The action of AAL is specific, since its effect is dose-dependent, saturable, and inhibited by an excess of fucose. Fucosidase treatment entirely abolishes reaggregation. In contrast, Anguilla anguilla agglutinin (AAA) binding to fucose in alpha(1-2)-linkage does not show any effects. Incubation with CAB4-a specific monoclonal antibody for fucose in alpha(1-6)-linkage-reduces spheroid size and shape. AAL does not much affect primary aggregation, but rather subsequent processes of cell proliferation and histogenesis. In particular, AAL inhibits uptake of bromo-desoxyuridine (BrdU), most efficiently so during days in vitro 2 (div2) and div3. As a consequence, the histological differentiation is entirely disturbed, as evidenced by vimentin immunostaining; particularly, rosettes are not forming and the radial glia scaffold is disorganized. We conclude that glycoproteins exhibiting fucose in alpha(1-6)-linkage may play major roles in early processes of retinal tissue formation.  (+info)

Glycosylation alterations of cells in late phase apoptosis from colon carcinomas. (4/168)

Comparisons of carbohydrate profiles between control and apoptotic colon carcinoma cells were performed by flow cytometry using a set of lectins and anti-carbohydrate antibodies. The six cell lines analyzed presented distinct carbohydrate profiles before induction of apoptosis. PHA-L and MAA binding decreased after induction of apoptosis by UV-treatment. In contrast an increase of PNA binding was observed after induction of apoptosis, except on SW-48 cells for which a decrease occurred. A decrease of SNA binding was observed after induction of apoptosis from strongly positive control cell lines, whereas it increased on weakly positive ones. All the blood group related antigens A, H, Lewis a, Lewis x, Lewis b, and Lewis y, had their expression strongly diminished on apoptotic cells. These changes occurred irrespective of the mode of apoptosis induction since similar results were obtained after UV, TNFalpha, or anti-Fas treatment. Fucosyltransferases activities were also decreased after apoptosis induction, except for alpha1,3fucosyltransferase in anti-Fas treated HT-29 cells, where it was strongly augmented. This could be attributed to the IFNgamma preteatment required to induce Fas expression on these cells. Fucosidase activity decreased after induction of apoptosis suggesting that it was not responsible for the loss of fucosylated structures. In the rat PRO cell line, H blood group antigens are mainly carried by a high molecular weight variant of CD44. It could be shown that the loss of H antigen after induction of apoptosis correlated with a loss of the carrier glycoprotein.  (+info)

Terminal glycosylation in cystic fibrosis. (5/168)

Cystic fibrosis (CF) is a common genetic disease for which the gene was identified within the last decade. Pulmonary disease predominates in this ultimately fatal disease and current therapy only slows the progression. CF transmembrane regulator (CFTR), the gene product, is an integral membrane glycoprotein that normally functions as a chloride channel in epithelial cells. The most common mutation, deltaF508, results in mislocalization and altered glycosylation of CFTR. Altered fucosylation and sialylation are hallmarks of both membrane and secreted glycoproteins in CF and the focus here is on these investigations. Oligosaccharides from CF membrane glycoproteins have the Lewis x, selectin ligand in terminal positions. In addition, two major bacterial pathogens in CF, Pseudomonas aeruginosa and Haemophilus influenzae, have binding proteins, which recognize fucose in alpha1,3 linkage and asialoglycoconjugates. We speculate that the altered terminal glycosylation of airway epithelial glycoproteins in CF contributes to the chronic infection and robust inflammatory response in the CF lung. Understanding the effects of mutant CFTR on glycosylation may provide further insight into the regulation of glycoconjugate processing as well as therapy for CF.  (+info)

Prediction of the development of hepato-cellular-carcinoma in patients with liver cirrhosis by the serial determinations of serum alpha-L-fucosidase activity. (6/168)

OBJECTIVE: Evaluation of the usefulness of the serial determinations of serum alpha-L-fucosidase (AFU) activity for prediction of the development of hepatocellular carcinoma (HCC) was performed. METHODS AND PATIENTS: Serum AFU activity was determined monthly for 42 months in 73 patients with liver cirrhosis (LC). RESULTS: HCC was diagnosed in 27 patients by means of ultrasonography during this observation period. In 23 (85%) of the 27 patients, serum AFU activity was found to exceed 700 nmole/ml/h during the LC stage. HCC developed within a few years in 23 (82%) of 28 LC patients with AFU activity exceeding 700 nmole/ml/h, in contrast, it developed in only 4 (9%) of 45 LC patients with AFU activity below 700 nmole/ml/h. AFU activity was already elevated in 23 (85%) of 27 patients at least 6 months before the detection of HCC by ultrasonography. CONCLUSION: It is conceivable that the development of HCC can be predicted by means of serial determinations of serum AFU activity in patients with LC.  (+info)

Endometrial lysosomal enzyme activity in ovulatory dysfunctional uterine bleeding, IUCD users and post-partum women. (7/168)

The aim of this study was to evaluate the role of lysosomal enzymes in excessively heavy menstruation by comparing women with menorrhagia due to dysfunctional bleeding or intrauterine contraceptive device (IUCD) use with those with normal menstrual periods or with amenorrhoea associated with breastfeeding. This was a prospective cohort investigation of the activity of four endometrial lysosomal enzymes in three contrasting groups: (i) women with ovulatory dysfunctional uterine bleeding and users of intrauterine contraceptive devices; (ii) breastfeeding post-partum women in whom there are long periods of amenorrhoea, particularly in the early months post-partum; and (iii) normal cycling women. It was found that the total activity of lysosomal enzymes, particularly acid phosphatase and N-acetyl-beta-D-glucosaminidase, was markedly elevated (P < 0.001) in IUCD-exposed endometrium, and endometrium from women with dysfunctional uterine bleeding when compared with endometrium from women with a history of entirely normal menstrual periods or that in post-partum breastfeeding women. The activity of alpha-L-fucosidase was moderately elevated in IUCD users (P < 0.05) and ovulatory dysfunctional uterine bleeding (P < 0.05), whereas alphaD-mannosidase activity was elevated in ovulatory dysfunctional uterine bleeding (P < 0.05), but decreased in IUCD users (P < 0.01). No significant differences were observed in the lysosomal enzyme activities of breastfeeding post-partum women and normal cycling women. These results show that total endometrial tissue activity of four lysosomal enzymes was substantially increased throughout the cycle in most circumstances in women with two different causes for increased menstrual bleeding. This suggests a contributory role to the increased bleeding.  (+info)

Sequence and expression of Thai Rosewood beta-glucosidase/beta-fucosidase, a family 1 glycosyl hydrolase glycoprotein. (8/168)

Dalcochinin-8'-O-beta-glucoside beta-glucosidase (dalcochinase) from the Thai rosewood (Dalbergia cochinchinensis Pierre) has aglycone specificity for isoflavonoids and can hydrolyze both beta-glucosides and beta-fucosides. To determine its structure and evolutionary lineage, the sequence of the enzyme was determined by peptide sequencing followed by PCR cloning. The cDNA included a reading frame coding for 547 amino acids including a 23 amino acid propeptide and a 524 amino acid mature protein. The sequences determined at peptide level were found in the cDNA sequence, indicating the sequence obtained was indeed the dalcochinase enzyme. The mature enzyme is 60% identical to the cyanogenic beta-glucosidase from white clover glycosyl hydrolase family 1, for which an X-ray crystal structure has been solved. Based on this homology, residues which may contribute to the different substrate specificities of the two enzymes were identified. Eight putative glycosylation sites were identified, and one was confirmed to be glycosylated by Edman degradation and mass spectrometry. The protein was expressed as a prepro-alpha-mating factor fusion in Pichia pastoris, and the activity of the secreted enzyme was characterized. The recombinant enzyme and the enzyme purified from seeds showed the same K(m) for pNP-glucoside and pNP-fucoside, had the same ratio of V(max) for these substrates, and similarly hydrolyzed the natural substrate, dalcochinin-8'-beta-glucoside.  (+info)

While the catalytic nucleophile in the configuration-retaining alpha-L-fucosidases from family GH29 is fully conserved with respect to sequence, there is no fully sequence-conserved acid/base residue candidate across the family. X-ray crystallographic studies and kinetic characterizations have allowed the identification of this residue in a few cases, and a recent combination of phylogenetic tree analyses with substrate specificity data has allowed the division of GH29 enzymes into two subfamilies, A and B, allowing the probable assignment of these residues. Here, we perform detailed kinetic and mechanistic characterizations of the corresponding alanine mutants and other candidates. Through comparison of kinetic parameters obtained for the hydrolysis of fucosyl substrates with activated leaving groups by these mutants with those of the corresponding wild-type enzymes, in conjunction with the demonstration of azide rescue, we largely confirm the acid/base residue predictions for the GH29 ...

Glycosylation drives critical processes important for mammalian cell-cell and cell-matrix interactions. Alpha-l-fucose (α-l-f) is a key monosaccharide component of oligosaccharides that has been found to be overexpressed during tumor progression. Modification of cell surface fucosylation, we hypothesized, alters tumor cell phenotype and function at the end of the neoplastic progression cascade including tumor invasion. Alpha-l-fucosidase (α-l-fase) is a glycosidase that specifically removes (α-l-f) from oligosaccharide sites. We first verified the effectiveness of the α-l-fase to specifically decrease the level of α-l-f on the cell surface of several human breast cancer cell lines and also examined the recovery time for these cells to repopulate their surfaces. To investigate the potential effect of defucosylation on tumor functions, we studied the proliferation, and invasion in vitro of human breast cancer MDA-MB-231 cells as the representative cell model. We further examined several ...

A series of phenyl-D-thioglucopyranosides were prepared and characterized in order to determine the absolute specificity of the .B-thioglucosidase and B-glucosidese enzyme systems toward the th1oglucosidic bond. The specificity of B-glucosidase of almond emulsin toward oxygen linkage seems to be absolute, since no hydrolysis was observed by this enzyme system toward the phenyl-D-thioglucopyranosides. The P-th1oglucosidase system was found to hydrolyze only two of the thioglucopyranosides. It was apparent that only where the electron-attracting substituents in the phenyl group were strong enough to greatly weaken the strength of the sulfur linkage, as in the case of the nitro group, would there be any hydrolysis. The lack of hydrolysis prevented application of the Hammett equation in testing the quantitative electronic effects of the substitutents on the rate of bond hydrolysis.

The molecular basis of the deficiency of alpha-L-fucosidase has been investigated in eight patients who had been diagnosed clinically and enzymatically as suffering from the autosomal recessive lysosomal storage disease fucosidosis. None of the patients had a deletion or gross alteration of the alpha-L-fucosidase gene (FUCA1). Single strand conformation polymorphism (SSCP) analysis followed by direct sequencing of amplified exons and flanking regions identified putative disease causing mutations in six of the patients, who had severe forms of the disease and very low residual alpha-L-fucosidase activity and protein. They were a 10 bp deletion in exon 1 (E113fs), a 1 bp deletion at position -2 of intron 2 (S216fs), a g--,a transition at IVS5+1, point mutations W183X and N329Y in exons 3 and 6, respectively, and a compound allele consisting of a point mutation in the signal peptide in exon 1, P5R, and a 1 bp insertion in exon 6 (Y330fs). One patient in whom an SSCP change was not detected had ...
Severe progressive fatal neurological degeneration occurs in fucosidosis, a storage disease. Bone marrow transplantation into affected dogs has shown that haematopoietic stem cells can provide enzyme producing daughter cells to the central nervous system, altering disease course. This makes canine fucosidosis an ideal large animal model for gene therapy. Fucosidosis affected allogeneic or autologous canine marrow was transduced ex vivo by cocultivation, then transplanted into fucosidosis affected dogs conditioned with total lymphoid irradiation. The vectors were Moloney murine leukaemia virus based. Transduction efficiency was increased with multiple cytokines in short term marrow culture. Despite high levels of transduction, proviral sequence was detected 2 months post transplant in only one dog. Early or total graft failure occurred in all transplants. We believe lack of engraftment could be caused by differentiation or change of repopulating ability of marrow cells occurring with multiple ...
The desire for improved methods of biomass conversion into fuels and feedstocks has re-awakened interest in the enzymology of plant cell wall degradation. The complex polysaccharide xyloglucan is abundant in plant matter, where it may account for up to 20% of the total primary cell wall carbohydrates. Despite this, few studies have focused on xyloglucan saccharification, which requires a consortium of enzymes including endo-xyloglucanases, alpha-xylosidases, beta-galactosidases and alpha-L-fucosidases, among others. In the present paper, we show the characterization of Xy131A, a key alpha-xylosidase in xyloglucan utilization by the model Gram-negative soil saprophyte Cellvibrio japonicus. CjXy131A exhibits high regiospecificity for the hydrolysis of XGOs (xylogluco-oligosaccharides), with a particular preference for longer substrates. Crystallographic structures of both the apo enzyme and the trapped covalent 5-fluoro-beta-xylosyl-enzyme intermediate, together with docking studies with the XXXG ...
Fucosidosis is a rare lysosomal storage disorder caused by the inherited deficiency of the lysosomal hydrolase α-L-fucosidase, which leads to an impaired degradation of fucosylated glycoconjugates. Here we report the generation of a fucosidosis mouse model, in which the gene for lysosomal α-L-fucosidase (Fuca1) was disrupted by gene targeting. Homozygous knock-out mice completely lack α-L-fucosidase activity in all tested organs leading to highly elevated amounts of the core-fucosylated glycoasparagine Fuc(α1,6)-GlcNAc(β1-N)-Asn and, to a lesser extent, other fucosylated glycoasparagines, which all were also partially excreted with the urine. Lysosomal storage pathology was observed in many visceral organs like liver, kidney, spleen and bladder as well as in the CNS. On the cellular level storage was characterized by membrane-limited cytoplasmic vacuoles primarily containing water-soluble storage material. In the CNS cellular alterations included enlargement of the lysosomal compartment in ...

Several 2-(aminomethyl)-and 2-(2-aminoethyl)-pyrrolidine-3,4-diol derivatives have been assayed for their inhibitory activities towards glycosidases. Good inhibitors of alpha-mannosidases must have the (2R,3R,4S) configuration and possess 2-(benzylamino)methyl substituents. Stereomers with the (2S,3R,4S) configuration are also competitive inhibitors of alpha-mannosidases, but less potent as they share the configuration of C(1), C(2), C(3) Of beta-D-mannosides rather than that Of alpha-D-mannosides. Interestingly, (2S,3R,4S)-2-{2-[(4-phenyl)phenylamino]ethyl}pyrrolidine-3,4-diol (12g) inhibits several enzymes, for instance alpha-L-fucosidase from bovine epididymis (K-i = 6.5 muM, competitive), alpha-galactosidase from bovine liver (K-i = 5 muM, mixed) and alpha-mannosidase from jack bean (K-i = 102 muM, mixed). Diamines such as (2R,3S,4R)-2-[2-(phenylamino) or 2-(benzylamino)ethyl]pyrrolidine-3,4-diol (ent-1 2a, ent-12b) inhibit P-glucosidase from almonds (K-i = 13-40 muM, competitive). (C) 2003 Elsevier

At least 26 mutations in the FUCA1 gene have been found to cause fucosidosis. Most of these mutations result in an abnormally short, nonfunctional alpha-L-fucosidase enzyme. Without this enzyme, glycolipids and glycoproteins cannot be completely broken down. These partially broken down compounds accumulate in the lysosomes and cause cells throughout the body to malfunction. Brain cells are particularly sensitive to the buildup of glycolipids and glycoproteins, which can result in cell death. Loss of brain cells is thought to cause the neurological symptoms of fucosidosis. Accumulation of glycolipids and glycoproteins also occurs in other organs such as the liver, spleen, skin, heart, pancreas, and kidneys, contributing to the additional symptoms of fucosidosis. ...

Fucosidosis is a rare, autosomal recessive lysosomal storage disorder caused by a severe deficiency of [alpha]-L-fucosidase.. Here we present a 27-month-old male who was referred to us for evaluation of developmental delay, which was first detected at age six months. His past medical history was also remarkable for recurrent pulmonary infections and myoclonic seiures. His family history revealed that he was the first living child from a consanguineous marriage. He had a younger sister who died at five months of age from pneumonia who had facial resemblance to the proband, developmental delay and a congenital heart defect.. Physical examination revealed length: 81 cm (25-50p), weight: 10.2 kg (25-50p), and head circumference: 49 cm (50-75p). He had a coarse face, hepatomegaly and generalized spasticity..

Background: Some salivary markers of alcohol abuse/dependence have been proposed so far: aminotransferases, gamma-glutamyltransferase, ethanol, ethyl glucuronide, ethyl sulfate, sialic acid, β-hexosaminidase A, oral peroxidase, methanol, diethylene/ethylene glycol, α-amylase, clusterin, haptoglobin, heavy/light chains of immunoglobulins and transferrin. Aim: To investigate the effect of chronic alcohol drinking and smoking on the activity (pKat/ml) and output (pKat/min) of salivary lysosomal exoglycosidases: α-fucosidase (FUC), α-mannosidase (MAN), β-galactosidase (GAL), and β-glucuronidase (GLU), and their applicability as markers of alcohol dependence. Methods: The activity of FUC, MAN, GAL and GLU was measured colorimetrically in the saliva of healthy social drinkers, alcohol-dependent non-smokers and alcohol-dependent smokers. Results: We observed an increased salivary activity of FUC, GAL, GLU and MAN, as well as an increased output of GAL and GLU, in comparison with controls. The ...

Sperm-associated antigen 8 is a protein that in humans is encoded by the SPAG8 gene. The correlation of anti-sperm antibodies with cases of unexplained infertility implicates a role for these antibodies in blocking fertilization. Improved diagnosis and treatment of immunologic infertility, as well as identification of proteins for targeted contraception, are dependent on the identification and characterization of relevant sperm antigens. The protein encoded by this gene is recognized by sperm agglutinating antibodies from an infertile woman. This protein is localized in germ cells of the testis at all stages of spermatogenesis and is localized to the acrosomal region of mature spermatozoa. Alternatively spliced variants that encode different protein isoforms have been described but the full-length sequences of only two have been determined.

OST is a component of the translocon in the endoplasmic reticulum (ER) membrane. A lipid-linked core-oligosaccharide is assembled at the membrane of the endoplasmic reticulum and transferred to selected asparagine residues of nascent polypeptide chains by the oligosaccharyl transferase complex.[3] The active site of OST is located about 4 nm from the lumenal face of the ER membrane.[4] It usually acts during translation as the nascent protein is entering the ER, but this cotranslational glycosylation is nevertheless called a posttranslational modification. A few examples have been found of OST activity after translation is complete.[5][6] Current opinion is that post-translational activity may occur if the protein is poorly folded or folds slowly.[6] ...
