Different regulation of the p53 core domain activities 3'-to-5' exonuclease and sequence-specific DNA binding. (1/552)

In this study we further characterized the 3'-5' exonuclease activity intrinsic to wild-type p53. We showed that this activity, like sequence-specific DNA binding, is mediated by the p53 core domain. Truncation of the C-terminal 30 amino acids of the p53 molecule enhanced the p53 exonuclease activity by at least 10-fold, indicating that this activity, like sequence-specific DNA binding, is negatively regulated by the C-terminal basic regulatory domain of p53. However, treatments which activated sequence-specific DNA binding of p53, like binding of the monoclonal antibody PAb421, which recognizes a C-terminal epitope on p53, or a higher phosphorylation status, strongly inhibited the p53 exonuclease activity. This suggests that at least on full-length p53, sequence-specific DNA binding and exonuclease activities are subject to different and seemingly opposing regulatory mechanisms. Following up the recent discovery in our laboratory that p53 recognizes and binds with high affinity to three-stranded DNA substrates mimicking early recombination intermediates (C. Dudenhoeffer, G. Rohaly, K. Will, W. Deppert, and L. Wiesmueller, Mol. Cell. Biol. 18:5332-5342), we asked whether such substrates might be degraded by the p53 exonuclease. Addition of Mg2+ ions to the binding assay indeed started the p53 exonuclease and promoted rapid degradation of the bound, but not of the unbound, substrate, indicating that specifically recognized targets can be subjected to exonucleolytic degradation by p53 under defined conditions.  (+info)

The cyclic structure of microcin J25, a 21-residue peptide antibiotic from Escherichia coli. (2/552)

Microcin J25 (MccJ25) is the single representative of the immunity group J of the microcin group of peptide antibiotics produced by Enterobacteriaceae. It induces bacterial filamentation in susceptible cells in a non-SOS-dependent pathway [R. A. Salomon and R. Farias (1992) J. Bacteriol. 174, 7428-7435]. MccJ25 was purified to homogeneity from the growth medium of a microcin-overproducing Escherichia coli strain by reverse-phase HPLC. Based on amino acid composition and absolute configuration determination, liquid secondary ion and electrospray mass spectrometry, extensive two-dimensional NMR, enzymatic and chemical degradations studies, the structure of MccJ25 was elucidated as a 21-residue peptide, cyclo(-Val1-Gly-Ile-Gly-Thr- Pro-Ile-Ser-Phe-Tyr-Gly-Gly-Gly-Ala-Gly-His-Val-Pro-Glu-Tyr-Phe21- ). Although MccJ25 showed high resistance to most of endoproteases, linearization by thermolysin occurred from cleavage at the Phe21-Val1 bond and led to a single peptide, MccJ25-L. While MccJ25 exhibited remarkable antibiotic activity towards Salmonella newport and several E. coli strains (minimal inhibitory concentrations ranging between 0.01 and 0.2 microgram.mL-1), the thermolysin-linearized microcin showed a dramatic decrease of the activity, indicating that the cyclic structure is essential for the MccJ25 biological properties. As MccJ25 is ribosomally synthesized as a larger peptide precursor endowed with an N-terminal extremity, the present study shows that removal of this extension and head-tail cyclization of the resulting propeptide are the only post-translational modifications involved in the maturation of MccJ25, that appears as the first cyclic microcin.  (+info)

Studies on the formation and stability of a complex between Streptomyces proteinaceous metalloprotease inhibitor and thermolysin. (3/552)

The effects of certain physicochemical parameters on the formation and stability of a complex between Streptomyces proteinaceous metalloprotease inhibitor (SMPI) and thermolysin were investigated. SMPI had its lowest Ki value at a pH of around 6.5 (similar to the pH dependence of the kcat/K(m) of thermolysin catalysis), reflecting the splitting mechanism of the SMPI inhibition of thermolysin. This Ki increased with an increase in pressure, and in (Ki-1) was almost linear with respect to pressure. The volume of the reaction (delta Vcomp), which is the volume change accompanying enzyme-inhibitor complex formation, was calculated as +8.1 +/- 0.3 mL.mol-1, which has a sign opposite to delta Vcomp for neutral peptide inhibitors and acyl-peptide substrates. The temperature dependence of Ki-1 gave the reaction enthalpy (delta Hcomp) and reaction entropy (delta Scomp) of the complex formation as 34.6 +/- 1.4 kJ.mol-1 and 298 +/- 5 J.mol-1.K-1, respectively. These positive reaction volumes and reaction entropies were related to the electrostatic interactions and ionic strength dependence of Ki which corresponded to the key ionic interaction during complex formation. Complex formation with SMPI stabilized thermolysin against pressure perturbation as observed by the changes in the Trp fluorescence of thermolysin with increasing pressure. Thermal stability, however, was affected very little by complex formation with SMPI. Phosphoramidon, Cbz-Phe-Gly-NH2 and Cbz-Phe also positively affected the pressure-tolerance of thermolysin, in the following order: Cbz-Gly-Phe-NH2 < Cbz-Phe << phosphoramidon. The third compound exhibited stabilizing effects comparable with those of SMPI, which suggests that the interaction between SMPI and thermolysin was localized to the reactive site.  (+info)

A Kazal-type trypsin inhibitor from the protochordate Ciona intestinalis. (4/552)

A trypsin inhibitor from Ciona intestinalis, present throughout the animal, was purified by ion-exchange chromatography followed by four HPLC steps. By MS the molecular mass of the native form was determined to be 6675 Da. The N-terminal amino acid sequence was determined by protein sequencing, but appeared to be partial because the theoretical molecular mass of the protein was 1101 Da too low. Thermolysin treatment gave rise to several fragments each containing a single disulphide bridge. By sequence analysis and MS intramolecular disulphide bridges could unequivocally be assigned to connect the pairs Cys4-Cys37, Cys8-Cys30 and Cys16-Cys51. The structure of the inhibitor is homologous to Kazal-type trypsin inhibitors. The inhibitor constant, KI, for trypsin inhibition was 0.05 nM whereas chymotrypsin and elastase were not inhibited. To reveal the complete sequence the cDNA encoding the trypsin inhibitor was isolated. This cDNA of 454 bp predicts a protein of 82 amino acid residues including a 20 amino acid signal peptide. Moreover, the cDNA predicts a C-terminal extension of 11 amino acids compared to the part identified by protein sequencing. The molecular mass calculated for this predicted protein is in accordance with the measured value. This C-terminal sequence is unusual for Kazal-type trypsin inhibitors and has apparently been lost early in evolution. The high degree of conservation around the active site strongly supports the importance of the Kazal-type inhibitors.  (+info)

Parvalbumin from rabbit muscle. Isolation and primary structure. (5/552)

A parvalbumin, with its characteristic low molecular weight (approximately 12000) acidic isoelectric point (approximately 5.5), ultraviolet spectrum (maxm 259 nm) and Ca2+-binding capacity (2 mol/mol protein) has been isolated from rabbit (Oryctolagus cuniculus) muscle. Its primary structure has been determined from a study of its tryptic peptides and of overlapping peptides generated by limited tryptic digestion and by chymotryptic and thermolytic digestions of the protein. The amino acid sequence so obtained is considered in comparison with those known for other parvalbumin and for rabbit troponin C.  (+info)

A three-dimensional construction of the active site (region 507-749) of human neutral endopeptidase (EC.3.4.24.11). (6/552)

A three-dimensional model of the 507-749 region of neutral endopeptidase-24.11 (NEP; E.C.3.4.24.11) was constructed integrating the results of secondary structure predictions and sequence homologies with the bacterial endopeptidase thermolysin. Additional data were extracted from the structure of two other metalloproteases, astacin and stromelysin. The resulting model accounts for the main biological properties of NEP and has been used to describe the environment close to the zinc atom defining the catalytic site. The analysis of several thiol inhibitors, complexed in the model active site, revealed the presence of a large hydrophobic pocket at the S1' subsite level. This is supported by the nature of the constitutive amino acids. The computed energies of bound inhibitors correspond with the relative affinities of the stereoisomers of benzofused macrocycle derivatives of thiorphan. The model could be used to facilitate the design of new NEP inhibitors, as illustrated in the paper.  (+info)

The compact conformation of fibronectin is determined by intramolecular ionic interactions. (7/552)

Fibronectin exists in a compact or extended conformation, depending upon environmental pH and salt concentration. Using recombinant fragments expressed in bacteria and baculovirus, we determined the domains responsible for producing fibronectin's compact conformation. Our velocity and equilibrium sedimentation data show that FN2-14 (a protein containing FN-III domains 2 through 14) forms dimers in low salt. Experiments with smaller fragments indicates that the compact conformation is produced by binding of FN12-14 of one subunit to FN2-3 of the other subunit in the dimer. The binding is weakened at higher salt concentrations, implying an electrostatic interaction. Furthermore, segment FN7-14+A, which contains the alternatively spliced A domain between FN11 and 12, forms dimers, whereas FN7-14 without A does not. Segment FN12-14+A also forms dimers, but the isolated A domain does not. These data imply an association of domain A with FN12-14, and the presence of A may favor an open conformation by competing with FN2-3 for binding to FN12-14.  (+info)

Insertion of atToc34 into the chloroplastic outer membrane is assisted by at least two proteinaceous components in the import system. (8/552)

Toc34 is a member of the outer membrane translocon complex that mediates the initial stage of protein import into chloroplasts. Toc34, like most outer membrane proteins, is synthesized in the cytosol at its mature size without a cleavable transit peptide. The majority of outer membrane proteins do not require thermolysin-sensitive components on the chloroplastic surface or ATP for their insertion into the outer membrane. However, different results have been obtained concerning the factors required for Toc34 insertion into the outer membrane. Using an Arabidopsis homologue of pea Toc34, atToc34, we show that the insertion of atToc34 was greatly reduced by thermolysin pretreatment of chloroplasts as assayed either by protease digestion or by alkaline extraction. The insertion was also dependent on the presence of ATP or GTP. A mutant of atToc34 with the GTP-binding domain deleted still required ATP for optimal insertion, indicating that ATP was used by other protein components in the import system. The ATP-supported insertion was observed even in thermolysin-pretreated chloroplasts, suggesting that the protein component responsible for ATP-stimulated insertion is a different protein from the thermolysin-sensitive component that assists atToc34 insertion.  (+info)

Topology analysis of membrane proteins can be obtained by enzymatic shaving in combination with MS identification of peptides. Ideally, such analysis could provide quite detailed information about the membrane spanning regions. Here, we examine the ability of some shaving enzymes to provide large-scale analysis of membrane proteome topologies. To compare different shaving enzymes, we first analyzed the detected peptides from two over-expressed proteins. Second, we analyzed the peptides from non-over-expressed Escherichia coli membrane proteins with known structure to evaluate the shaving methods. Finally, the identified peptides were used to test the accuracy of a number of topology predictors. At the end we suggest that the usage of thermolysin, an enzyme working at the natural pH of the cell for membrane shaving, is superior because: (i) we detect a similar number of peptides and proteins using thermolysin and trypsin; (ii) thermolysin shaving can be run at a natural pH and (iii) the ...
TY - JOUR. T1 - A proteolytic fragment from the central region of p53 has marked sequence-specific DNA-binding activity when generated from wild-type but not from oncogenic mutant p53 protein.

N2 - p53 is a sequence-specific DNA-binding oligomeric protein that can activate transcription from promoters bearing p53-binding sites. Whereas the activation region of p53 has been identified within the amino terminus, the location of the specific DNA-binding domain has not been reported. Thermolysin treatment of p53 protein generates a stable protease-resistant fragment that binds with marked specificity to p53 DNA-binding sites. Amino-terminal sequencing of the fragment located the thennolysin cleavage site to residue 91. Because the fragment does not contain the cdc2 phosphorylation site at Ser-315, we conclude that the the site-specific DNA-binding domain of p53 spans ...

Hereditary mutations in the transforming growth factor beta induced (TGFBI) gene cause phenotypically distinct corneal dystrophies characterized by protein deposition in cornea. We show here that the Arg555Trp mutant of the fourth fasciclin 1 (FAS1-4) domain of the protein (TGFBIp/keratoepithelin/betaig-h3), associated with granular corneal dystrophy type 1, is significantly less susceptible to proteolysis by thermolysin and trypsin than the WT domain. High-resolution liquid-state NMR of the WT and Arg555Trp mutant FAS1-4 domains revealed very similar structures except for the region around position 555. The Arg555Trp substitution causes Trp555 to be buried in an otherwise empty hydrophobic cavity of the FAS1-4 domain. The first thermolysin cleavage in the core of the FAS1-4 domain occurs on the N-terminal side of Leu558 adjacent to the Arg555 mutation. MD simulations indicated that the C-terminal end of helix alpha3 containing this cleavage site is less flexible in the mutant domain, ...
Enzymatic hydrolysis of proteins is used to improve nutritional and functional properties of many foods. The desired degree of hydrolysis (DH) depends on food application. Effective hydrolysis requires optimal hydrolysis conditions for both the enzyme and the substrate protein. This study aimed to hydrolyze the oat globulins (OG) effectively under different conditions. Our first goal was to maximise the OG solubility and then to hydrolyze OG under optimised conditions. The solubility of isolated OG in Na-phosphate solutions containing 0 1 M NaCl was determined. Globulins were subjected to single-enzyme hydrolysis with either subtilisin, thermolysin or pepsin. In addition, OG were degraded in two-stage hydrolysis first with pepsin and then either with subtilisin or thermolysin. The hydrolysates were analysed by SDS-PAGE and DH was quantified with the OPA method. The solubility of OG increased when NaCl was added at pH 5 10. Under more acidic conditions the solubility, however, decreased with ...
0047] The above characteristics are optionally taken into account when producing a protein with reduced or improved enzymatic activity. Illustratively, substitutions in a substrate binding site, exosite, cofactor binding site, catalytic site, or other site in an enzyme may alter the activity of the enzyme toward a substrate. In considering such substitutions the sequences of other known naturally occurring or non-naturally occurring proteins may be taken into account. Illustratively, mutations of L134R and S320A in Bacillis licheniformis α-amylase improve the catalytic activity of the enzyme in acidic conditions 14-fold.

As another example, a corresponding mutation to that of Asp213 in thermolysin is operable such as that done by Mild, Y, et al., Journal of Molecular Catalysis B: Enzymatic, 1996; 1:191-199. Optionally, a substitution in thermolysin of L144S alone or along with substitutions of G8C/N60C/S65P are operable to increase the ...
Is able to inhibit all four classes of proteinases by a unique trapping mechanism. This protein has a peptide stretch, called the bait region which contains specific cleavage sites for different proteinases. When a proteinase cleaves the bait region, a conformational change is induced in the protein which traps the proteinase. The entrapped enzyme remains active against low molecular weight substrates (activity against high molecular weight substrates is greatly reduced). Following cleavage in the bait region a thioester bond is hydrolyzed and mediates the covalent binding of the protein to the proteinase (By similarity). Displays inhibitory activity against chymotrypsin, papain, thermolysin, subtilisin A and, to a lesser extent, elastase but not trypsin. May play an important role during desquamation by inhibiting extracellular proteases ...

Over 70 metallopeptidase families have been identified to date. In these enzymes a divalent cation which is usually zinc, but may be cobalt, manganese or copper, activates the water molecule. The metal ion is held in place by amino acid ligands, usually three in number. In some families of co-catalytic metallopeptidases, two metal ions are observed in crystal structures ligated by five amino acids, with one amino acid ligating both metal ions. The known metal ligands are His, Glu, Asp or Lys. At least one other residue is required for catalysis, which may play an electrophillic role. Many metalloproteases contain an HEXXH motif, which has been shown in crystallographic studies to form part of the metal-binding site [(PUBMED:7674922)]. The HEXXH motif is relatively common, but can be more stringently defined for metalloproteases as abXHEbbHbc, where a is most often valine or threonine and forms part of the S1 subsite in thermolysin and neprilysin, b is an uncharged residue, and c a ...
In 1 we will find the explanation of clinical results obtained by intravenous CH1 injections, even if the blood pH did not change.. In 2 we find the reason for clinical results obtained by increasing neutral salts intake. Ambard gives the following reaction:. NaCl+2CO3 NaHCO3+HCl. Whereas this reaction gives birth to infinitesimal quantities of HCl, if it takes place in the presence of albumin, the acid will impregnate the albumin and a new quantity of NaCl can be decomposed and liberates a new fraction of chlorine.. Here then we have first of all a new characteristic of proteins. It is therefore possible to perceive, that though the proteins are charged with acid, the medium many manifest a neutral reaction. Chabanier and Lobo-Onell have shown that even an increase of acid, producing an acidemia (of the medium), will allow the albumins to discharge themselves of HCl if the neutral salt content is diminished. It is possible, therefore, to have an acidemia (of the medium) and an alkalosis (of the ...
In well-known methods of estimating rates of irreversible disposal (utilization) in vivo the rates are calculated from the areas to infinity under specific radioactivity-time (S-t) or quantity-of-label-time (q-t) curves obtained by measurements on samples of plasma after intravenous injection of labelled substrate. The errors in the calculated rates are mostly those of the estimates of the areas. These errors are of two kinds: random, caused by the variances of the values of S or q, and systematic, caused by differences between the curves used to interpolate between these values and the true curves. A rigorous method is given for calculating the random errors from the variances of the values of S or q, and is applied to choosing the best times to sample the plasma from small animals from which few plasma samples can be taken. A procedure for estimating systematic errors is also given. Programs in BASIC language to carry out the calculations are deposited as Supplementary Publication SUP 50058 (5 ...

Here we present the synthesis and post-polymerisation modification of poly(acryloyl hydrazide), a versatile scaffold for the preparation of functional polymers: poly(acryloyl hydrazide) was prepared from commercially available starting materials in a three step synthesis on a large scale, in good yields and high purity. Our synthetic approach included the synthesis of a Boc-protected acryloyl hydrazide, the preparation of polymers via RAFT polymerisation and the deprotection of the corresponding Boc-protected poly(acryloyl hydrazide). Post-polymerisation modification of poly(acryloyl hydrazide) was then demonstrated using a range of conditions for both hydrophilic and hydrophobic aldehydes. These experiments demonstrate the potential of poly(acryloyl hydrazide) as a scaffold in the synthesis of functional polymers, in particular those applications where in situ screening of the activity of the functionalised polymers may be required (e.g. biological applications ...

0022]The (meth)acryloyl groups in the linear (meth)acryloyl-containing compound of the present invention exist at parts of side chains relative to the molecular chain having the longest coupling length in a single molecule, and it is indispensable from the standpoint of satisfactory hardenability and sensitivity that an average of 3 or more be contained in a single molecule. With respect to the pertinent (meth)acryloyl groups, by selecting the structural units which configure the straight-chain portion, it is possible to easily adjust their concentration in a single molecule, that is, the molecular weight per (meth)acryloyl group. For example, when using residue excluding 2 hydroxyl groups from bisphenol as A in the aforementioned general formula (1) as described below, it is possible to obtain approximately the same concentration as with conventional bifunctional epoxy(meth)acrylate, and to have crosslink density in an appropriate range while having multifunctionality, thereby obtaining ...

The amino acid sequence of the plastocyanin from the green alga Chlorella fusca was determined. The protein consists of a single polypeptide chain of 98 residues, and was determined by characterization of chymotryptic and thermolysin peptides. The amino acid sequence shows considerable similarity to that of higher plant plastocyanins. The protein contains a single cysteine, and the sequence in the vicinity of this residue is similar to that around the cysteine residue of bacterial azurins. The plastocyanin contains some uncharacterized carbohydrate. Detailed evidence for the sequence of the protein has been deposited as Supplementary Publication SUP 50 036 (17pp., 1 microfiche) at the British Library (Lending Division) (formerly the National Lending Library for Science and Technology), Boston Spa, Yorks.

N2 - Aerogels, because of their porosity, have a great ability to adsorb water, and this characteristic was exploited to extend the applicability of aerogels for the adsorption and entrapment of hydrolases to be used in organic media. The applicability of aerogels as solid supports for immobilisation of the enzymes PGA, thermolysin and α-chymotrypsin was assayed. By controlling the distribution of water between the catalyst, the support and the reaction medium, aerogel preserves the catalytic activity of the enzymes and prevents hydrolytic reactions. © 2000 Elsevier Science Ltd..

Background: Effective digestive enzymes are crucial for successful islet isolation. Supplemental proteases are essential because they synergize with collagenase for effective pancreatic digestion. The activity of these enzymes is critically dependent on the presence of Ca2+ ions at a concentration of 5-10 mM. The present study aimed to determine the Ca2+ concentration during human islet isolation and to ascertain whether the addition of supplementary Ca2+ is required to maintain an optimal Ca2+ concentration during the various phases of the islet isolation process.. Methods: Human islets were isolated according to standard methods and isolation parameters. Islet quality control and the number of isolations fulfilling standard transplantation criteria were evaluated. Ca2+ was determined by using standard clinical chemistry routines. Islet isolation was performed with or without addition of supplementary Ca2+ to reach a Ca2+ of 5 mM.. Results: Ca2+ concentration was markedly reduced in ...
