The Saccharomyces cerevisiae CWH8 gene is required for full levels of dolichol-linked oligosaccharides in the endoplasmic reticulum and for efficient N-glycosylation. (1/1662)

The Saccharomyces cerevisiae mutant cwh8 was previously found to have an anomalous cell wall. Here we show that the cwh8 mutant has an N -glycosylation defect. We found that cwh8 cells were resistant to vanadate and sensitive to hygromycin B, and produced glycoforms of invertase and carboxypeptidase Y with a reduced number of N -chains. We have cloned the CWH8 gene. We found that it was nonessential and encoded a putative transmembrane protein of 239 amino acids. Comparison of the in vitro oligosaccharyl transferase activities of membrane preparations from wild type or cwh8 Delta cells revealed no differences in enzyme kinetic properties indicating that the oligosaccharyl transferase complex of mutant cells was not affected. cwh8 Delta cells also produced normal dolichols and dolichol-linked oligosaccharide intermediates including the full-length form Glc3Man9GlcNAc2. The level of dolichol-linked oligosaccharides in cwh8 Delta cells was, however, reduced to about 20% of the wild type. We propose that inefficient N -glycosylation of secretory proteins in cwh8 Delta cells is caused by an insufficient supply of dolichol-linked oligosaccharide substrate.  (+info)

Isolation and characterization of two mouse L cell lines resistant to the toxic lectin ricin. (2/1662)

Two variant mouse L cell lines (termed CL 3 and CL 6) have been selected for resistant to ricin, a galactose-binding lectin with potent cytotoxic activity. The resistant lines exhibit a 50 to 70% decrease in ricin binding and a 300- to 500-fold increase in resistance to the toxic effects of ricin. Crude membrane preparations of CL 3 cells have increased sialic acid content (200% of control), while the galactose, mannose, and hexosamine content is within normal limits. Both the glycoproteins and glycolipids of CL 3 cells have increased sialic acid, with the GM3:lactosylceramide ratios for parent L and CL 3 cells being 0.29 and 1.5, respectively. In contrast, the membranes of CL 6 cells have a decrease in sialic acid, galactose, and hexosamine content with mannose being normal. Both cell lines have specific alterations in glycosyltransferase activities which can account for the observed membrane sugar changes. CL 3 cells have increased CMP-sialic acid:glycoprotein sialyltransferase and GM3 synthetase activities, while CL 6 cells have decrease UDP-GlcNAc:glycoproteinN-acetylglucosaminyltransferase and DPU-galactose:glycoprotein galactosyltransferase activities. The increased sialic acid content of CL 3 cells serves to mask ricin binding sites, since neuraminidase treatment of this cell line restores ricin binding to essentially normal levels. However, the fact that neuraminidase-treated CL 3 cells are still 45-fold resistant to ricin indicates that either a special class of productive ricin binding sites is not being exposed or that the cell line has a second mechanism for ricin resistance.  (+info)

Hyaluronan synthase expression in bovine eyes. (3/1662)

PURPOSE: Hyaluronan (HA), a high-molecular-weight linear glycosaminoglycan, is a component of the extracellular matrix (ECM). It is expressed in eyes and plays important roles in many biologic processes, including cell migration, proliferation, and differentiation. Hyaluronan is produced by HA synthase (HAS), which has three isoforms: HAS1, HAS2, and HAS3. In this study, the HAS expression in the anterior segment of bovine eyes was investigated to determine the significance of HA in eyes. METHODS: To obtain bovine HAS probes, degenerate oligonucleotide primers, based on well-conserved amino acid sequences including the catalytic region of each HAS isoform, were used for reverse transcription-polymerase chain reaction to amplify mRNA from bovine corneal endothelial cells (BCECs). Hyaluronan synthase-1 expression in the anterior segment of bovine eyes at the protein level was investigated by immunohistochemistry. RESULTS: All three HAS isoforms were expressed in BCECs at the mRNA level. Amplified cDNA fragments of HAS1, HAS2, and HAS3 from BCECs can be aligned to human counterparts, showing similarities of 100%, 97.3%, and 100%, respectively, at the amino acid level. Hyaluronan synthase 1 was expressed at the protein level in corneal epithelium, keratocyte, corneal endothelium, conjunctival epithelium, ciliary epithelium, capillary endothelium, and trabecular meshwork. CONCLUSIONS: Hyaluronan synthase isoforms were expressed in the ocular anterior segment and are speculated to be involved in HA production in situ.  (+info)

Behavior of transaldolase (EC and transketolase (EC Activities in normal, neoplastic, differentiating, and regenerating liver. (4/1662)

The objective of this investigation was to throw light on the biological behavior and metabolic regulation of hepatic enzymes of the nonoxidative branch of the pentose phosphate pathway. The activities of transaldolase (EC and trasketolase (EC Were compared in biological conditions that involve modulation of gene expression such as in starvation, in differentiation, after partial hepatectomy, and in a spectrum of hepatomas of different growth rates. The enzyme activities were determined under optimal kinetic conditions by spectrophotometric methods in the 100,000 X g supernatant fluids prepared from tissue homogenates. The kinetic properties of transaldolase and transketolase were similar in normal liver and in rapidly growing hepatoma 3924A. For transaldolase, apparent Km values of 0.13 mM (normal liver) and 0.17 mM (hepatoma) were observed for erythrose 4-phosphate and of 0.30 to 0.35 mM for fructose 6-phosphate. The pH optima in liver and hepatoma were at approximately 6.9 to 7.2. For the transketolase substrates, ribose 5-phosphate and xylulose 5-phosphate, the apparent Km values were 0.3 and 0.5 mM, respectively, in both liver and hepatoma. A broad pH optimum around 7.6 was observed in both tissues. In organ distribution studies, enzyme activities were measured in liver, intestinal mucosa, thymus, kidney, spleen, brain, adipose tissue, lung, heart, and skeletal muscle. Taking the specific activity of liver as 100%, transaldolase activity was the highest in intestinal mucosa (316%) and in thymus (219%); it was the lowest in heart (53%) and in skeletal muscle (21%). Transketolase activity was highest in kidney (155%) and lowest in heart (26%) and skeletal muscle (23%). Starvation decreased transaldolase and transketolase activities in 6 days to 69 and 74%, respectively, of those of the liver of the normal, fed rat. This was in the same range as the decrease in the protein concentration (66%y. In the liver tumors, transaldolase activity was increased 1.5- to 3.4-fold over the activities observed in normal control rat liver. Transketolase activity showed no relationship to tumor proliferation rate. In the regenerating liver at 24 hr after partial hepatectomy, the activity of both pentose phosphate pathway enzymes was in the same range as that of the sham-operated controls. In differentiation at the postnatal age of 5, 12, 23, and 32 days, hepatic transaldolase activities were 33, 44, 55, and 72%, respectively, of the activities observed in the 60-day-old, adult male rat. During the same period, transketolase activ-ties were 18, 21, 26, and 55% of the activities observed in liver of adult rat. The demonstration of increased transaldolase activity in hepatomas, irrespective of the degree of tumor malignancy, differentiation, or growth rate, suggests that the reprogramming of gene expression in malignant transformation is linked with an increase in the expression of this pentose phosphate pathway enzyme...  (+info)

A 20-kDa domain is required for phosphatidic acid-induced allosteric activation of phospholipase D from Streptomyces chromofuscus. (5/1662)

Two phospholipase D (PLD) enzymes with both hydrolase and transferase activities were isolated from Streptomyces chromofuscus. There were substantial differences in the kinetic properties of the two PLD enzymes towards monomeric, micellar, and vesicle substrates. The most striking difference was that the higher molecular weight enzyme (PLD57 approximately 57 kDa) could be activated allosterically with a low mole fraction of phosphatidic acid (PA) incorporated into a PC bilayer (Geng et al., J. Biol. Chem. 273 (1998) 12195-12202). PLD42/20, a tightly associated complex of two peptides, one of 42 kDa and the other 20 kDa, had a 4-6-fold higher Vmax toward PC substrates than PLD57 and was not activated by PA. N-Terminal sequencing of both enzymes indicated that both components of PLD42/20 were cleavage products of PLD57. The larger component included the N-terminal segment of PLD57 and contained the active site. The N-terminus of the smaller peptide corresponded to the C-terminal region of PLD57; this peptide had no PLD activity by itself. Increasing the pH of PLD42/20 to 8.9, followed by chromatography of PLD42/20 on a HiTrap Q column at pH 8.5 separated the 42- and 20-kDa proteins. The 42-kDa complex had about the same specific activity with or without the 20-kDa fragment. The lack of PA activation for the 42-kDa protein and for PLD42/20 indicates that an intact C-terminal region of PLD57 is necessary for activation by PA. Furthermore, the mechanism for transmission of the allosteric signal requires an intact PLD57.  (+info)

Serine transhydroxymethylase from rabbit liver. Sequence of anonapeptide at the pyridoxal-5'-phosphate-binding site. (6/1662)

The amino acid sequence of the coenzyme-binding site of serine transhydroxymethylase from rabbit liver has been determined. After reduction with NaBH4 and aminoethylation, a first sample of enzyme was digested with thermolysin and a single phosphopyridoxyl peptide was isolated. A second sample of similarly treated enzyme was digested with chymotrypsin and three phosphopyridoxyl peptides clearly originating from a unique coenzyme-binding site were isolated. Sequence analysis of these peptides indicate the following structure: Val-Val-Thr-Thr-His(Pxy)-Thr-Leu. Sequence homologies of the active site of various pyridoxalphosphate enzymes are discussed in terms of a possible catalytic role and of evolution of this class of proteins.  (+info)

Bordetella pertussis waaA encodes a monofunctional 2-keto-3-deoxy-D-manno-octulosonic acid transferase that can complement an Escherichia coli waaA mutation. (7/1662)

Bordetella pertussis lipopolysaccharide (LPS) contains a single 2-keto-3-deoxy-D-manno-octulosonic acid (Kdo) residue, whereas LPS from Escherichia coli contains at least two. Here we report that B. pertussis waaA encodes an enzyme capable of transferring only a single Kdo during the biosynthesis of LPS and that this activity is sufficient to complement an E. coli waaA mutation.  (+info)

Expression of prokaryotic 1-deoxy-D-xylulose-5-phosphatases in Escherichia coli increases carotenoid and ubiquinone biosynthesis. (8/1662)

Isopentenyl diphosphate (IPP) acts as the common, five-carbon building block in the biosynthesis of all isoprenoids. The first reaction of IPP biosynthesis in Escherichia coli is the formation of 1-deoxy-D-xylulose-5-phosphate, catalysed by 1-deoxy-D-xylulose-5-phosphate synthase (DXPS). E. coli engineered to produce lycopene, was transformed with dxps genes cloned from Bacillus subtilis and Synechocystis sp. 6803. Increases in lycopene levels were observed in strains expressing exogenous DXPS compared to controls. The recombinant strains also exhibited elevated levels of ubiquinone-8. These increases corresponded with enhanced DXP synthase activity in the recombinant E. coli strains.  (+info)

The Escherichia coliglycine cleavage enzyme system catalyzes the cleavage of glycine into carbon dioxide, ammonia, and 5,10-methylenetetrahydrofolate (9). Glycine is required for both protein and purine biosynthesis, while 5,10-methylenetetrahydrofolate serves as a one-carbon donor in the biosynthesis of purines, methionine, thymine, and numerous methylated products (15). Three components of the glycine cleavage enzyme system, the GcvT, GcvH, and GcvP proteins, are encoded by the gcv operon (17). Induced by glycine (13, 17, 28) and repressed by purines (8, 27), it appears that expression of the gcv operon is regulated in order to balance cellular requirements for glycine and one-carbon units.. Currently, four proteins, the leucine-responsive regulatory protein (Lrp), the purine repressor protein (PurR), the glycine cleavage activator protein (GcvA), and the glycine cleavage repressor protein (GcvR), have been shown to be involved in regulating expression of thegcv operon. Lrp is a global ...
Listeria monocytogenes is a facultative intracellular bacterial pathogen that escapes from phagosomes and induces a robust adaptive immune response in mice, while mutants unable to escape phagosomes fail to induce a robust adaptive immune response and suppress the immunity to wildtype bacteria when co-administered. The capacity to suppress immunity can be reversed by blocking IL-10. In this study, we sought to understand the host receptors that lead to secretion of IL-10 in response to phagosome-confined L. monocytogenes (Δhly), with the ultimate goal of generating strains that fail to induce IL-10. We conducted a transposon screen to identify Δhly L. monocytogenes mutants that induced significantly more or less IL-10 secretion in bone marrow-derived macrophages (BMMs). A transposon insertion in lgt, which encodes phosphatidylglycerol-prolipoprotein diacylglyceryl transferase and is essential for the formation of lipoproteins, induced significantly reduced IL-10 secretion. Mutants with ...
A catalytic mechanism has been proposed for CH in analogy with that for TS (Graves et al., 1992). During the initial steps, they both catalyze the transfer of a methylene group from CH2H4folate to C‐5 of either dCMP or dUMP (Carreras and Santi, 1995; Figure 3). 18O‐exchange studies indicated the existence of a 5‐exocyclic methylene intermediate in the reaction mechanism of T4 CH (Butler et al., 1994). The same intermediate was also proposed for TSs (Stroud and Finer‐Moore, 1993). The catalytic activities of these enzymes are differentiated by the last step of the proposed mechanisms. During this critical step, T4 CH catalyzes the hydroxylation of the methylene group to produce Hm‐dCMP without oxidizing the cofactor, whereas TS catalyzes the reduction of the exocyclic methylene to a methyl group with a concomitant oxidation of the cofactor to dihydrofolate. In the TS‐catalyzed reaction, the C‐6 hydrogen of the pterin ring of the folate cofactor is donated to the exocyclic methylene ...

A leaky rice mutant was isolated from an ethylmethane sulfonate (EMS)-mutagenized rice library based on its short root phenotype. The map-based cloning results showed that the mutant was due to a point mutation in the intron of OsDGL1 (LOC_Os07g10830), which encodes the dolichyl-diphosphooligosaccharide-protein glycosyltransferase 48 kDa subunit precursor. The mutation results in premature termination of protein synthesis. OsDGL1 is an ortholog of Arabidopsis DGL1, human OST48 and yeast WBP1, an essential protein subunit of the oligosaccharyltransferase (OST) complex, which is involved in N-glycosylation in eukaryotes. The leaky rice mutant, Osdgl1, displayed a change of matrix polysaccharides in its root cell wall, shorter root cell length, smaller root meristem and cell death in the root. Consistent with the known function of the OST complex in eukaryotes, the Osdgl1 mutation leads to a defect in N-glycosylation in the root. It was also found that reactive oxygen species (ROS) may be involved ...
Background-Statins have anti-inflammatory and antiatherogenic effects that have been attributed to inhibition of RHO protein geranylgeranylation in inflammatory cells. The activity of protein geranylgeranyltransferase type I (GGTase-I) is widely believed to promote membrane association and activation of RHO family proteins. However, we recently showed that knockout of GGTase-I in macrophages activates RHO proteins and proinflammatory signaling pathways, leading to increased cytokine production and rheumatoid arthritis. In this study, we asked whether the increased inflammatory signaling of GGTase-I-deficient macrophages would influence the development of atherosclerosis in LDL receptor-deficient mice. Methods and Results-Aortic lesions in mice lacking GGTase-I in macrophages (Pggt1bΔ/Δ) contained significantly more T lymphocytes than the lesions in controls. Surprisingly, however, mean atherosclerotic lesion area in Pggt1bΔ/Δ mice was reduced by ~60%. GGTase-I deficiency reduced the ...

1MXC: Structure and function of S-adenosylmethionine synthetase: crystal structures of S-adenosylmethionine synthetase with ADP, BrADP, and PPi at 28 angstroms resolution.
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] ...

polysaccharide capsules (CPS) are characterized by the presence of nonstoichiometric -methyl phosphoramidate (MeOPN) modifications. The lack of stoichiometry is due to phase variation at homopolymeric tracts within the MeOPN transferase genes. strain 81-176 contains two MeOPN transferase genes and has been shown previously to contain MeOPN modifications at the 2 and 6 positions of the galactose (Gal) moiety in the CPS. We demonstrate here that one of the two MeOPN transferases, encoded by CJJ81176_1435, is bifunctional and is responsible for the addition of MeOPN to both the 2 and the 6 positions of Gal. A new MeOPN at the 4 position of Gal was observed in a mutant lacking the CJJ81176_1435 transferase and this was encoded by the CJJ81176_1420 transferase. During routine growth of 81-176, the CJJ81176_1420 transferase was predominantly in an off configuration, while the CJJ81176_1435 transferase was primarily on. However, exposure to normal human serum selected for cells expressing the ...

Catalyzes consecutive E-type condensation of two isopentenyl pyrophosphate (IPP) molecules with an allylic substrate such as geranylgeranyl diphosphate (GGPP), farnesyl diphosphate (FPP) or geranyl diphosphate (GPP) to yield the medium-chain product trans-C30-hexaprenyl pyrophosphate (HexPP). GGPP is the physiological substrate.
With DHDDS, forms the dehydrodolichyl diphosphate synthase (DDS) complex, an essential component of the dolichol monophosphate (Dol-P) biosynthetic machinery. Adds multiple copies of isopentenyl pyrophosphate (IPP) to farnesyl pyrophosphate (FPP) to produce dehydrodolichyl diphosphate (Dedol-PP), a precursor of dolichol which is utilized as a sugar carrier in protein glycosylation in the endoplasmic reticulum (ER). Regulates the glycosylation and stability of nascent NPC2, thereby promoting trafficking of LDL-derived cholesterol.
2014, The Society for In Vitro Biology. The present study aimed to demonstrate the phenomena of hyaluronan synthesis in response to lipopolysaccharide-induced inflammation in SW982, a human synovial sarcoma cell line. The expression of IL-1ß, including Toll-like receptor 4 and IL-1ß-converting enzyme, was proved to be induced by a reverse transcription-polymerase chain reaction. The expression of HAS genes encoding enzyme hyaluronan synthase 2 and 3, including CD44 gene which encodes the cell surface receptor of hyaluronan were upregulated in association with the activation of inflammation, along with an increase in hyaluronan level in the culture medium. The highest expression of HAS2 and HAS3 was found at 9 h after treatment with lipopolysaccharide. However, HAS1 gene expression was not detectable neither with the non-treatment nor with the treatment with lipopolysaccharide. Dexamethasone at 30 nM significantly suppressed lipopolysaccharide-induced HAS genes expression, leading to the ...
CAS# 121268-17-5 Description of Alendronate sodium: Alendronate sodium is the sodium salt of alendronate, a second generation bisphosphonate and synthetic analog of pyrophosphate with bone anti-resorption activity. Alendronate sodium binds to and inhibits the activity of geranyltranstransferase (farnesyl pyrophosphate synthetase), an enzyme involved in terpenoid biosynthesis. Inhibition of this enzyme prevents the biosynthesis of isoprenoid lipids (FPP and GGPP) that are donor substrates of farnesylation and geranylgeranylation during the post-translational modification of small GTPase signalling proteins, which is important in the process of osteoclast turnover. As a result, osteoclast activity is inhibited and bone resorption and turnover are reduced.

Construction of a helical wheel model for transmembrane helix 9 of MraY and the transmembrane domain of protein E enabled the identification of an Arg-Trp-x-x-Trp (RWxxW) motif in protein E that might interact with Phe288 of MraY and the neighbouring Glu287. This motif is also found in a number of cationic antimicrobial peptide sequences. Synthetic dipeptides and pentapeptides based on the RWxxW consensus sequence showed inhibition of ...

TY - JOUR. T1 - Substrate specificity of bacterial oligosaccharyltransferase suggests a common transfer mechanism for the bacterial and eukaryotic systems. AU - Wacker, Michael. AU - Feldman, Mario F.. AU - Callewaert, Nico. AU - Kowarik, Michael. AU - Clarke, Bradley R.. AU - Pohl, Nicola L.. AU - Hernandez, Marcela. AU - Vines, Enrique D.. AU - Valvano, Miguel A.. AU - Whitfield, Chris. AU - Aebi, Markus. PY - 2006/5/2. Y1 - 2006/5/2. N2 - The PglB oligosaccharyltransferase (OTase) of Campylobacter jejuni can be functionally expressed in Escherichia coli, and its relaxed oligosaccharide substrate specificity allows the transfer of different glycans from the lipid carrier undecaprenyl pyrophosphate to an acceptor protein. To investigate the substrate specificity of PglB, we tested the transfer of a set of lipid-linked polysaccharides in E. coli and Salmonella enterica serovar Typhimurium. A hexose linked to the C-6 of the monosaccharide at the reducing end did not inhibit the transfer of the O ...
Like the other amino acids used by cells, selenocysteine has a specialized tRNA. The primary and secondary structure of selenocysteine tRNA, tRNA(Sec), differ from those of standard tRNAs in several respects, most notably in having an 8-base (bacteria) or 9-base (eukaryotes) pair acceptor stem, a long variable region arm, and substitutions at several well-conserved base positions. The selenocysteine tRNAs are initially charged with serine by seryl-tRNA ligase, but the resulting Ser-tRNA(Sec) is not used for translation because it is not recognised by the normal translation factor (EF-Tu in bacteria, EF1alpha in eukaryotes). Rather, the tRNA-bound seryl residue is converted to a selenocysteyl-residue by the pyridoxal phosphate-containing enzyme selenocysteine synthase. Finally, the resulting Sec-tRNA(Sec) is specifically bound to an alternative translational elongation factor (SelB or mSelB) which delivers it in a targeted manner to the ribosomes translating mRNAs for selenoproteins. The ...
Rheumatoid arthritis is a painful and debilitating inflammatory disorder with no known cure. It has been hypothesised that targeting the activity of RHO family proteins might be an effective therapeutic strategy, as these proteins are required for the function of macrophages, which contribute to immunopathology in arthritic joints. However, this notion is challenged in a recent paper by Khan et al. Unexpectedly, mice deficient for a key RHO-activating enzyme, geranylgeranyltransferase type I (GGTase-I), specifically in macrophages were found to develop spontaneous and severe joint inflammation resembling erosive rheumatoid arthritis. Macrophage-specific deficiency in GGTase-I was sufficient to induce pro-inflammatory signalling pathways and initiate the disease owing to sustained activation of RHO family proteins in macrophages. These data indicate that GGTase-I is not essential for the activity of RHO family proteins, and that inhibition of this enzyme can worsen, rather than prevent, the ...
