Endometrial lysosomal enzyme activity in normal cycling endometrium. (1/346)

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)

Mid2 is a putative sensor for cell integrity signaling in Saccharomyces cerevisiae. (2/346)

Hcs77 is a putative cell surface sensor for cell integrity signaling in Saccharomyces cerevisiae. Its loss of function results in cell lysis during growth at elevated temperatures (e.g., 39 degrees C) and impaired signaling to the Mpk1 mitogen-activated protein kinase in response to mild heat shock. We isolated the MID2 gene as a dosage suppressor of the cell lysis defect of an hcs77 null mutant. MID2 encodes a putative membrane protein whose function is required for survival of pheromone treatment. Mid2 possesses properties similar to those of Hcs77, including a single transmembrane domain and a long region that is rich in seryl and threonyl residues. We demonstrate that Mid2 is required for cell integrity signaling in response to pheromone. Additionally, we show that Mid2 and Hcs77 serve a redundant but essential function as cell surface sensors for cell integrity signaling during vegetative growth. Both proteins are uniformly distributed through the plasma membrane and are highly O-mannosylated on their extracellular domains. Finally, we identified a yeast homolog of MID2, designated MTL1, which provides a partially redundant function with MID2 for cell integrity signaling during vegetative growth at elevated temperature but not for survival of pheromone treatment. We conclude that Hcs77 is dedicated to signaling cell wall stress during vegetative growth and that Mid2 participates in this signaling, but its primary role is in signaling wall stress during pheromone-induced morphogenesis.  (+info)

Purification and biochemical characterization of two soluble alpha-mannosidases from Candida albicans. (3/346)

Two soluble alpha-mannosidases, E-I and E-II, were purified from C. albicans yeast cells by a three-step procedure consisting of size exclusion and ion exchange chromatographies in Sepharose CL6B and Mono Q columns, respectively, and preparative nondenaturing electrophoresis. E-I and E-II migrated as monomeric polypeptides of 54.3 and 93.3 kDa in SDS-PAGE, respectively. Some biochemical properties of purified enzymes were investigated by using 4-methylumbelliferyl-alpha-D-mannopyranoside and p-nitrophenyl-alpha-D-mannopyranoside as substrates. Hydrolysis of both substrates by either enzyme was optimum at pH 6.0 with 50 mM Mes-Tris buffer and at 42 degrees C. Apparent Kmvalues for hydrolysis of 4-methylumbelliferyl-alpha-D-mannopyranoside and p-nitrophenyl-alpha-D-mannopyranoside by E-I were 0.83 microM and 2. 4 mM, respectively. Corresponding values for E-II were 0.25 microM and 1.86 mM. Swansonine and deoxymannojirimicin strongly inhibited the hydrolysis of 4-methylumbelliferyl-alpha-D-mannopyranoside by both enzymes. On the contrary, hydrolysis of p-nitrophenyl-alpha-D-mannopyranoside by E-I and E-II was slightly stimulated or not affected, respectively, by both inhibitors. E-I and E-II did not depend on metal ions although activity of the latter was slightly stimulated by Mn2+and Ca2+in the range of 0.5-2 mM. At the same concentrations, Mg2+was slightly inhibitory of both enzymes. Substrate specificity experiments revealed that both E-I and E-II preferentially cleaved alpha-1,6 and alpha-1,3 linkages, respectively.  (+info)

Characterization of a soluble class I alpha-mannosidase in human serum. (4/346)

Class I alpha-mannosidases are thought to exist exclusively as integral membrane proteins that play intracellulary an essential role in the N-glycan biosynthesis. Using [3H]Man9GlcNAc2 as a substrate, we were able to identify a soluble alpha-mannosidase in human serum that trims the substrate Man9GlcNAc2 to Man(5-8)GlcNAc2 with Man6GlcNAc2 being the major product. This serum mannosidase is Ca2+-dependent, sensitive to 1-deoxymannojirimycin but insensitive to the class II inhibitor swainsonine and, hence, belongs to class I mannosidases. The enzymatic properties of the serum class I mannosidase are similar to that of the membrane bound class I mannosidases Golgi-mannosidase IA and IB and Man9-mannosidase.  (+info)

Androgen regulation of glycosidase secretion in epithelial cell cultures from human epididymis. (5/346)

The human epididymis and its secretions actively promote sperm fertilizing capacity and provide protection for spermatozoa against harmful influences. Among epididymal secretions, glycosidases have been recently studied and associated with molecular changes on the sperm surface. In the present work, we studied the influence of different concentrations of testosterone, dihydrotestosterone and cyproterone acetate on the secretion of alpha-glucosidase, N-acetyl-glucosaminidase, beta-glucuronidase and alpha-mannosidase by isolated and cultured epithelial cells from human caput, corpus and cauda epididymides. Cell cultures were obtained from aggregates of isolated tubule fragments plated on extracellular matrix-covered multi-well plates. Activities of the glycosidases were measured in conditioned culture media and were higher in the distal regions of the epididymis. Testosterone and dihydrotestosterone significantly increase the enzyme secretion in a concentration-dependent manner. This increase was higher in corpus and/or cauda than in caput epididymis. Cyproterone acetate caused a dose-dependent decrease in glycosidase secretion in cultures from all epididymal regions. It is concluded that the secretion of epididymal glycosidases is regulated by androgen, being stimulated by dihydrotestosterone and testosterone and inhibited by the androgen antagonist cyproterone acetate.  (+info)

Topological and functional characterization of the N-glycans of soybean (Glycine max) agglutinin. (6/346)

Soybean agglutinin (SBA), is a noncovalently bound tetramer comprised of four identical subunits having a single N-glycan chain, Man9GlcNAc2, that is known to be essential for regeneration of the functional tetrameric structure from unfolded subunits. In this study, SBA was found to have strong affinity for concanavalin A, indicating that the N-glycans are extensively solvent-exposed. The susceptibilities of the N-glycans to alpha-mannosidase and endo-beta-N-acetylglucosaminidase revealed that their distal areas have nonreducing ends embedded among the subunits, whereas their proximal regions are solvent-exposed. Endo-beta-N-acetylglucosaminidase-digested SBA was unable to retain its conformation and gradually unfolded. Periodate-oxidized SBA, whose N-glycans closely correspond to the invariant pentasaccharide core, tended to dissociate into the subunits, but permitted to stay as folded monomers. This SBA species was capable of refolding from unfolded subunits but unable to form the functional tetramer. It seems probable that the proximal regions of the N-glycans function in the formation and stabilization of the subunit conformation, whereas the branches outside the invariant cores stabilize the tetrameric structure.  (+info)

Targeted disruption of the lysosomal alpha-mannosidase gene results in mice resembling a mild form of human alpha-mannosidosis. (7/346)

Alpha-mannosidosis is a lysosomal storage disease with autosomal recessive inheritance caused by a deficiency of the lysosomal alpha-mannosidase, which is involved in the degradation of asparagine-linked carbohydrate cores of glycoproteins. An alpha-mannosidosis mouse model was generated by targeted disruption of the gene for lysosomal alpha-mannosidase. Homozygous mutant animals exhibit alpha-mannosidase enzyme deficiency and elevated urinary secretion of mannose-containing oligosaccharides. Thin-layer chromatography revealed an accumulation of oligosaccharides in liver, kidney, spleen, testis and brain. The cellular alterations were characterized by multiple membrane-limited cytoplasmic vacuoles as seen for instance in liver, exocrine pancreas, kidney, thyroid gland, smooth muscle cells, osteocytes and in various neurons of the central and peripheral nervous systems. The morphological lesions and their topographical distribution, as well as the biochemical alterations, closely resemble those reported for human alpha-mannosidosis. This mouse model will be a valuable tool for studying the pathogenesis of inherited alpha-mannosidosis and may help to evaluate therapeutic approaches for lysosomal storage diseases.  (+info)

Purification and properties of major alpha-D-mannosidase in the luminal fluid of porcine epididymis. (8/346)

A lysosomal type alpha-D-mannosidase was successfully purified by DEAE-Sephacel, Red-Amicon and Superdex 200 column chromatographies from porcine cauda epididymal fluid. The purified enzyme consisted of 63 and 51 kDa subunits at equimolar amounts. It cleaved alpha1-2 linked mannosyl residues and less but significantly cleaved alpha1-3 and alpha1-6 linked mannosyl residues in the high-mannose oligosaccharides. The optimal pH to hydrolyze oligosaccharide was in the acidic pH range (pH 3.5 approximately 4.0). Total alpha-D-mannosidase activities in the porcine epididymal fluid increased from proximal to distal caput epididymis, which maintained to cauda epididymis. At least two kinds of alpha-D-mannosidase (lysosomal type enzyme and 135 kDa alpha-D-mannosidase (MAN2B2)) were contained in the porcine epididymal fluid. The activity of the lysosomal type enzyme is much higher than MAN2B2 at the physiological pH. These results suggest that the lysosomal type alpha-D-mannosidase is the predominantly active enzyme in the luminal fluid of porcine epididymis and that it participates in the glycoprotein modification on the sperm surface during epididymal transit.  (+info)

Seeds of Triticale (hybrid of wheat and rye) contain an N-acetylglucosamine specific lectin that was affinity purified in our laboratory (Siva Kumar, N. and Padma, K. (1996) Affinity purification of N-acetyl glucosamine specific lectin. Purification and partial characterization of Triticale lectin. Biochem. Mol. Biol. Int. 38, 1059-1066). Seed extracts also exhibited alpha-mannosidase activity that was isolated by a combination of ion exchange, hydrophobic chromatography and gel filtration. The purified enzyme is a glycoprotein with 7% carbohydrate and exhibited a native molecular mass of 1,95,000 (+/-5000) on Biogel P-200 and dissociated into two major subunits under reducing conditions of molecular masses 58 and 40 kDa, respectively. Both subunits cross-reacted with an antibody to the well-characterized jack bean alpha-mannosidase, suggesting antigenic similarity between the legume and the cereal mannosidases. Purified enzyme binds to Con A-Sepharose gel, possibly through the sugar-binding site.

In eukaryotes, class I alpha-mannosidases are involved in early N-glycan processing reactions and in N-glycan-dependent quality control in the endoplasmic reticulum (ER). To investigate the role of these enzymes in plants, we identified the ER-type alpha-mannosidase I (MNS3) and the two Golgi-alpha-mannosidase I proteins (MNS1 and MNS2) from Arabidopsis thaliana. All three MNS proteins were found to localize in punctate mobile structures reminiscent of Golgi bodies. Recombinant forms of the MNS proteins were able to process oligomannosidic N-glycans. While MNS3 efficiently cleaved off one selected alpha 1,2-mannose residue from Man(9)GlcNAc(2), MNS1/2 readily removed three alpha 1,2-mannose residues from Man(8)GlcNAc(2). Mutation in the MNS genes resulted in the formation of aberrant N-glycans in the mns3 single mutant and Man(8)GlcNAc(2) accumulation in the mns1 mns2 double mutant. N-glycan analysis in the mns triple mutant revealed the almost exclusive presence of Man(9)GlcNAc(2), ...

Alpha Mannosidosis is a progressive disorder, and its presence should be suspected in patients with cognitive disabilities, skeletal changes (e.g. swollen joints, curved spine), hearing loss and recurrent infections. Although children with the condition are often born seemingly normal, their condition deteriorates with age. Alpha-mannosidosis can impact on a patients quality of life in many ways, including their ability to live independently, socialise or find employment.[2][7] Generally, phenotypes of alpha-mannosidosis patients are not clearly distinguishable, which makes a prediction of the clinical course for an individual patient challenging.[2] Patients may present to doctors, nurses or health visitors at different stages of progression, and with different ad hoc symptoms, making the link to suspect a diagnosis of alpha-mannosidosis difficult.[2] The main symptoms can also be shared with those of other lysosomal storage disorders, such as mucopolysaccharidosis.[2] Given the progressive ...

Cytosolic α-mannosidases are glycosyl hydrolases that participate in the catabolism of cytosolic free N-oligosaccharides. Two soluble α-mannosidases (E-I and E-II) belonging to glycosyl hydrolases family 47 have been described in Candida albicans. We demonstrate that addition of pepstatin A during the preparation of cell homogenates enriched α-mannosidase E-I at the expense of E-II, indicating that the latter is generated by proteolysis during cell disruption. E-I corresponded to a polypeptide of 52 kDa that was associated with mannosidase activity and was recognized by an anti-α1,2-mannosidase antibody. The N-mannan core trimming properties of the purified enzyme E-I were consistent with its classification as a family 47 α1,2-mannosidase. Differential density-gradient centrifugation of homogenates revealed that α1,2-mannosidase E-I was localized to the cytosolic fraction and Golgi-derived vesicles, and that a 65 kDa membrane-bound α1,2-mannosidase was present in endoplasmic reticulum and Golgi

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
In this diploma thesis the adsorption of cobalt ions on egg shells was studied depending on the different initial concentrations of cobalt ions solutions (4.488 mmol dm-3, 8.365 mmol dm-3, 11.427 mmol dm-3, 20.814 mmol dm-3, and 31.223 mmol dm-3) at a constant temperature of 28°C, stirring speed of 200 rpm for 96 h. Egg shells with diameter d , 125 m were used as adsorbent while the concentrations of cobalt ions in equilibrium solutions were determined spectrophotometrically. Based on the results obtained, it can be concluded that the amount of adsorbed cobalt ions (qe) increases with the increase of the equilibrium concentration of cobalt ions in solution (ce) reaching value of qe = 0.163 mmol g-1 that represents the equilibrium amount of adsorbed cobalt ions on egg shells. The adsorption efficiency of cobalt ions reaches its maximum value of 9.758 % at initial concentration of 8.365 mmol dm-3 and then decreases with the increase of initial concentration of cobalt ions in solution.

β-mannosidase (EC 3.2.1.25, MANB) dissects the non-reducing end of N-linked mannose moieties of glycoproteins in eukaryotic cells. The human β-mannosidase gene was amplified by RT-PCR, cloned and sequenced. The DNA sequence was compared with reported human β-mannosidase DNA sequence and sixteen nucleotide differences were found. The deduced amino-acid sequence showed that seven codons coded the same amino acids and nine codons coded different amino acids with reference to nucleotide substitution positions but did not affect recombinant MANB enzyme activity. No splice mutation was observed after comparison with reported MANB DNA sequences. A 75% homology of deduced amino-acid sequence was observed with mouse, goat and bovine β-mannosidase amino-acid sequences. The cloned β-mannosidase gene was subcloned into pET22b+ and pET28a+ expression vectors to transform the BL21-codon plus cells for expression of recombinant MAN22 and MAN28 enzymes, respectively. The optimized conditions for ...

The animals involved in the study are born with a genetic disorder directly analogous to alpha-mannosidosis or AMD, an inherited disease in humans that causes severe mental retardation and skeletal abnormalities. Cats with AMD do not live more than six months. Children born with the worst form of the disease rarely survive into their teens. Through gene therapy, we replace a broken gene responsible for alpha-mannosidase with the correct, functioning copy, to dramatic results, said John H. Wolfe, a professor of pathology and medical genetics at the Penn School of Veterinary Medicine and a neurology researcher at Children s Hospital. The treated cats were markedly improved compared to diseased cats, with better balance and muscle control and fewer tremors ...
A recent study in Genetics in Medicine aiming at the identification by whole-exome sequencing of genes involved in infantile nystagmus found heterozygous missense mutations in the MANBA gene, which the encodes lysosomal beta-mannosidase. The mutations resulted in decrease of ?-mannosidase activities in the patients as well as in mutant-transfected HEK293T cells. MANBA is expressed in the pretectal nucleus of the developing midbrain, […]. ...

Teringat dulu saya hampir terlupa tentang ini..bukan tidak tahu tapi jarang diamalkan oleh masyarakat Malaysia termasuklah saya..jadi sebelum makan ubat baca bismillah dan doa. Saya tersedar ketika menghadiri satu kuliah agama di mana ustaz tu mengingatkan kembali pergantungan kita kepada Allah. Ustaz kata bagusnya kalau pergi di mana sahaja semua mengingatkan kita kepada Allah, seperti kos farmasi ketika nak bagi ubat kat pesakit, perlu cakap Allah yang menyembuhkan,ubat ini sebagai usaha kita, kos kejuteraan contohnya kejuteraan mekanikal..mesin dicipta mendapat perhatian seluruh dunia bagi memudahkan pekerjaan manusia seharian tetapi pencipta mesin iaitu jurutera itu berkata pada wartawan atau pada seluruh ummat bahawa mesin yang dicipta tak dapat menandingi kehebatan Allah dan bidang kejuruteraan kimia membuktikan zarah-zarah di udara bergerak membentuk kalimah Allah, begitu juga air yang bila mana dibaca kalimah yang baik seperti kalimah Allah terhasillah rupa bentuk zarah air yang indah ...

Meletakkan hukum syariat yang berlaku bagi semua manusia dalam bidang ibadah, muamalah dan segenap urusan mereka, memutuskan persengketaan dan perseteruan di antara mereka adalah hak mutlak Allah Taala sebagai pencipta manusia. Allah Taala berfirman, Ingatlah, menciptakan dan memerintah hanyalah hak Allah. (Al-Araf: 59).. Sebagai pencipta, secara otomatis Allah mengetahui ciptaanNya, Allah mengetahui manusia sebagai hambaNya, apa yang baik dan apa yang buruk bagi mereka, sehingga Dia meletakkan tatanan dan aturan sebagai konsekuensi dari rububiyahNya dan manusia patut menerima tatanan dan aturan tersebut sebagai tuntutan dari penghambaan dan demi kemaslahatan mereka sendiri.. Tentang sesuatu apapun kamu berselisih, maka putusannya (terserah) kepada Allah. Itulah Allah Tuhanku, kepadaNya lah aku bertawakkal dan kepadaNyalah aku kembali. (Asy-Syura: 10).. Karena hak menetapkan syariat hanya di tangan Allah, maka tidak pantas bagi siapa pun untuk mengakui hak tersebut, baik dengan ...
