BRITISH JOURNAL OF RHEUMATOLOGY 1996;35:133-8. [PMID: 8612024 DOI: 10.1093/rheumatology/35.2.133] [Citation(s) in RCA: 204] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Indexed: 01/31/2023] Abstract The objective was to determine whether the frequency of flare in systemic lupus erythematosus (SLE), patients is increased during pregnancy and the puerperium. Seventy-eight pregnancies in 68 SLE patients attending the lupus pregnancy clinic, at St. Thomas' Hospital, during the last 5 yr were included. The pregnancy period and 8 weeks post-delivery were considered. This group was compared with a control group of 50 consecutive, non-pregnant, age-matched SLE patients attending our weekly lupus clinic. Additionally, 43 of the pregnant patients carried on attending the lupus clinic for the year after puerperium, and their course was compared with themselves during pregnancy. SLE activity was assessed using the Lupus Activity Index (LAI) score. An increase > or = 0.26 in the score was considered as a flare of the disease. Pregnancy and control groups were homogeneous for age, race, disease duration and distribution of autoantibodies. Sixty-five per cent of the patients flared during pregnancy and/or the puerperium and 42% flared in the control group (P = 0.015). The rates of flare per patients/month were 0.082 +/- 0.004 for the pregnancy group and 0.039 +/- 0.003 for the control group (P < 0.001). The 43 patients whose course was controlled after the puerperium flared more frequently during pregnancy that thereafter (McNemar test, P = 0.003). The rates of flare per patient/month were 0.093 +/- 0.006 during pregnancy and the puerperium, and 0.049 +/- 0.004 after the puerperium (P = 0.0015). Kidney and central nervous system involvement was not different between the pregnancy and control groups. In terms of frequency of flares, there was no difference in any of the groups between patients taking and not taking steroids. We conclude that SLE tends to flare during pregnancy. Flares are maximal during the second and third trimester and the puerperium. Flares are not more severe than in non-pregnant patients, and most of the flares can be managed conservatively. Prednisolone does not prevent flares.

DNA cleavage assays of the resulting mutant proteins indicate that the largest effects on nucleolytic activity result from substitution of Asp74, Asp90, and Lys92. We suggest on the basis of structural information, mutagenesis data, and analogies with other nucleases that Asp74 and Asp90 might be involved in Mg2+ binding and/or catalysis and that Lys92 probably stabilizes the pentacovalent phosphorus in the transition state. These amino acids are part of a sequence motif, Pro-Asp...Asp/Glu-X-Lys, which is also present in EcoRI. In both enzymes, it is located in a structurally similar context near the scissile phosphodiester bond. A preliminary mutational analysis with EcoRI indicates that this sequence motif is of similar functional importance for EcoRI and EcoRV. On the basis of these results, a proposal is made for the mechanism of DNA cleavage by EcoRV and EcoRI.

In a previously reported microarray study, we found NF-kappaB pathway genes differentially expressed between peripheral (PTCL) and lymphoblastic lymphomas. Here, we investigated the expression of NF-kappaB pathway genes using cDNA microarrays in a group of 62 PTCL and in reactive lymph nodes. We found two different subgroups of PTCL based on the expression of NF-kappaB pathway genes. One-third of PTCL showed clearly reduced expression of NF-kappaB genes, while the other group was characterized by high expression of these genes. This distinction was found among all T-cell lymphoma categories analyzed (PTCL unspecified, angioimmunoblastic, cutaneous and natural killer/T lymphomas) with the exception of anaplastic lymphomas (ALCL), which were characterized by reduced NF-kappaB expression in anaplastic cells. Quantitative RT-PCR and immunohistochemical analysis of NF-kappaB-p65 protein confirmed these differences among PTCL subgroups. Importantly, we found that differentiation between NF-kappaB-positive and -negative PTCL could be of clinical interest. The expression profile associated to reduced expression of NF-kappaB genes was significantly associated with shorter survival of patients and seems to be an independent prognostic factor in a multivariate analysis.

This procedure uses DNA substrates that are labeled with biotin on one 5' end and with an antigenic group, e.g., fluorescein or digoxigenin, on the other 5' end. After incubation with the restriction enzyme, the reaction is stopped with EDTA and an aliquot is pipetted into the well of an avidin-coated microtiter plate. This immobilizes the unreacted substrate and the biotinylated cleavage product, whereas the other cleavage product labeled with the antigenic group is subsequently washed off. The unreacted substrate is detected by an enzyme-linked immunosorbent assay with an appropriate enzyme-linked antibody. To test our assay we have measured the steady-state rate constants for cleavage of DNA by EcoRI yielding a kcat of 8.6 min-1 and a Km of 150 nM, which are close to values measured with other assays. The advantage of this assay is that it is not only fast and accurate, but also very sensitive. It allows for many samples to be analyzed in parallel and lends itself to automation. Furthermore, this assay can be designed as a competitive assay, when two substrates carrying different antigenic groups are used.

Based on molecular modeling, we have proposed recently that the attacking water molecule is activated by the negatively charged pro-Rp phosphoryl oxygen of the phosphate group 3' to the scissile phosphodiester bond. We now present experimental evidence to support this proposal. (i) Oligodeoxynucleotide substrates lacking this phosphate group in one strand are cleaved only in the other strand. (ii) Oligodeoxynucleotide substrates carrying an H-phosphonate substitution at this position in both strands and, therefore, lacking a negatively charged oxygen at this position are cleaved at least four orders of magnitude more slowly than the unmodified substrate. These results are supported by other modification studies: oligodeoxynucleotide substrates with a phosphorothioate substitution at this position in both strands are cleaved only if the negatively charged sulfur is in the RP configuration as shown for EcoRI [Koziolkiewicz, M. & Stec, W.J. (1992) Biochemistry 31, 9460-9466] and EcoRV (B. A. Connolly, personal communication). As the phosphate residue 3' to the scissile phosphodiester bond is not needed for strong DNA binding by both enzymes, these findings strongly suggest that this phosphate group plays an active role during catalysis. This proposal, furthermore, gives a straightforward explanation of why in the EcoRI-DNA and EcoRV-DNA complexes the DNA is distorted differently, but in each case the 3' phosphate group closely approaches the phosphate group that is attacked. Finally, an alternative mechanism for DNA cleavage involving two metal ions is unlikely in the light of our finding that both EcoRI and EcoRV need only one Mg2+ per active site for cleavage.

It is employed by the restriction endonuclease EcoRI as well as many other proteins interacting with specific DNA sequences to locate their target sites on the macromolecular substrate. In order to investigate biochemical and biophysical details of the linear diffusion process, we have developed a competitive cleavage assay which allows us to assess with great accuracy the influence of sequence, sequence context, and other structural features on the linear diffusion of EcoRI on DNA. We show here that linear diffusion is not a hopping but a sliding movement in which EcoRI follows the helical pitch of the DNA, because it does not "overlook" any cleavage site. Linear diffusion is slowed when EcoRI encounters sites on the DNA which resemble its recognition site ("star" sites). Pauses of up to 20 s are induced, depending on sequence and orientation of the star site. These data suggest that EcoRI can bind to DNA in two binding modes: one tight, specific, and immobile, leading to DNA cleavage, and another one loose and nonspecific, allowing for linear diffusion. Depending on the similarity between the recognition sequence and the DNA sequence being encountered by EcoRI, there will be a continuous transition between these binding modes. Other proteins bound to the DNA and irregular DNA structures such as bent DNA or a triple helix constitute a barrier that cannot easily be passed by EcoRI.

These single strands can be combined with their complementary single strands to obtain all possible EcoRI sequences (left), or they can be combined with a single strand containing the canonical sequence to obtain double strands with all possible mismatches within the recognition sequence (right): (sequence; see text) The rate of phosphodiester bond cleavage of these oligodeoxynucleotides by EcoRI was determined in single-turnover experiments under normal buffer conditions in order to find out to what extent the canonical recognition site can be distorted and yet serve as a substrate for EcoRI. Our results show that oligodeoxynucleotides containing mismatch base pairs are in general more readily attacked by EcoRI than oligodeoxynucleotides containing EcoRI sites and that the rates of cleavage of the two complementary strands of degenerate oligodeoxynucleotides are quite different. We have also determined the affinities of these oligodeoxynucleotides to EcoRI. They are higher for oligodeoxynucleotides carrying a mismatch within the EcoRI recognition site than for oligodeoxynucleotides containing an EcoRI site but otherwise do not correlate with the rate with which these oligodeoxynucleotides are cleaved by EcoRI. Our results allow details to be given for the probability of EcoRI making mistakes in cleaving DNA not only in its recognition sequence but also in sequences closely related to it. Due to the fact that the rates of cleavage in the two strands of a degenerate sequence generally are widely different, these mistakes are most likely not occurring in vivo, since nicked intermediates can be repaired by DNA ligase.

PATIENTS AND METHODS Plasma 8-epi-PGF2alpha (oxidative stress marker) was measured by gas chromatography-mass spectrometry in 36 patients with systemic lupus erythematosus (SLE), 13 with systemic sclerosis (SSc), 13 with systemic vasculitis [Wegener's granulomatosis (WG), n = 4; Churg Strauss syndrome (CSS), n = 3; Behcet syndrome, n = 6], 12 with rheumatoid arthritis (RA) and in 23 healthy controls (n = 23). RESULTS 8-epi-PGF2alpha levels were higher in patients with SLE (P = 0.007), SSc (P < 0.001) and vasculitis (P = 0.001) than in controls. In SLE, a positive Coombs' test and arterial hypertension independently predicted 8-epi-PGF2alpha concentrations (P = 0.004 and P = 0.001, respectively). SLE patients not taking prednisolone showed higher 8-epi-PGF2alpha concentrations than SLE patients on prednisolone (P = 0.02). In the latter group, a dose response relationship was noted between 8-epi-PGF2alpha and steroid dosage (r = 0.6, P = 0.0003). In WG and CSS, 8-epi-PGF2alpha concentrations correlated with disease activity (r = 0.8, P = 0.01) and were higher than in patients with Behcet disease (P = 0.003). CONCLUSIONS Oxidative stress may be pathogenetically relevant in some autoimmune rheumatic diseases with vascular involvement. Amelioration of some clinical manifestations of these diseases may be envisaged by targeting lipid peroxidation with dietary or pharmacological antioxidants.

(1986) Science 234, 1526], sequence specificity is mediated by 12 hydrogen bonds, 6 from each of the two identical subunits of the dimeric enzyme to the recognition site -GAATTC-: Arg200 forms two hydrogen bonds with guanine, while Glu144 and Arg145 form four hydrogen bonds to adjacent adenine residues. Changing the hydrogen-bonding potential at the recognition site without perturbing the rest of the interface should lead to the recognition of degenerate sequences [Rosenberg et al. (1987) in Protein Engineering (Oxender, D. L., & Fox, C. F., Eds.) pp 237-250, Liss, New York]. We have shown previously that replacing Glu144 by Gln and Arg145 by Lys affects the activity of the enzyme, not, however, its specificity [Wolfes et al. (1986) Nucleic Acids Res. 14, 9063]. We show now that also the mutation of Arg200 to Lys, the double mutation Glu144Arg145 to GlnLys, and the triple mutation Glu144Arg145Arg200 to GlnLysLys do not lead to a detectable degeneracy of the specificity of cleavage by EcoRI but significantly impair the catalytic activity of this enzyme. A detailed analysis of the steady-state kinetics of cleavage of pUC8 DNA and a tridecadeoxynucleotide substrate demonstrates that the reduction in activity for all DNA binding site mutants investigated so far is mainly due to a decrease in kcat, with the exception of the Arg200 to Lys mutant, which is only impaired in its KM.(ABSTRACT TRUNCATED AT 250 WORDS) Collapse Key Words Collapse MESH Headings Base Sequence Binding Sites DNA/metabolism Deoxyribonuclease EcoRI/genetics Deoxyribonuclease EcoRI/metabolism Escherichia coli/enzymology Kinetics Molecular Sequence Data Mutation Oligodeoxyribonucleotides/metabolism Protein Conformation Substrate Specificity Collapse Grants Collapse		36	62

Therefore, it is possible to perform DNA binding experiments with the EcoRV-D90A mutant both in the absence and in the presence of Mg2+. Like wild-type EcoRV [Taylor et al. (1991) Biochemistry 30, 8743-8753], it does not show a pronounced specificity for binding to its recognition site in the absence of Mg2+ as judged by the appearance of multiple shifted bands in an electrophoretic mobility shift assay with a 377-bp DNA fragment carrying a single EcoRV recognition sequence. In the presence of Mg2+, however, only one band corresponding to a 1:1 complex appears even with a high excess of protein over DNA. This complex most likely is the specific one, because its formation is suppressed much more effectively by a 13-bp oligodeoxynucleotide with an EcoRV site than by a corresponding oligodeoxynucleotide without an EcoRV site. The preferential interaction of the EcoRV-D90A mutant with specific DNA in the presence of Mg2+ was also demonstrated directly: a 20-bp oligodeoxynucleotide with an EcoRV site is bound with KAss = 4 x 10(8) M-1, while a corresponding oligodeoxynucleotide without an EcoRV site is bound with KAss less than or equal to 1 x 10(5) M-1. From these data it appears that Mg2+ confers DNA binding specificity to this mutant by lowering the affinity to nonspecific sites and raising the affinity to specific sites as compared to binding in the absence of Mg2+. It is concluded that this is also true for wild-type EcoRV.

The maintenance of cellular and intraorganelle ionic homeostasis, particularly for Ca2+, can determine cell survival or death. Mitochondrial death decision is centered on two processes: inner membrane permeabilization, such as that promoted by the mitochondrial permeability transition pore, formed across inner membranes when Ca2+ reaches a critical threshold, and mitochondrial outer membrane permeabilization, in which the pro-apoptotic proteins BID, BAX, and BAK play active roles. Membrane permeabilization leads to the release of apoptogenic proteins: cytochrome c, apoptosis-inducing factor, Smac/Diablo, HtrA2/Omi, and endonuclease G. Cytochrome c initiates the proteolytic activation of caspases, which in turn cleave hundreds of proteins to produce the morphological and biochemical changes of apoptosis. Voltage-dependent anion channel, cyclophilin D, adenine nucleotide translocase, and the pro-apoptotic proteins BID, BAX, and BAK may be part of the molecular composition of membrane pores leading to mitochondrial permeabilization, but this remains a central question to be resolved. Other transporting pores and channels, including the ceramide channel, the mitochondrial apoptosis-induced channel, as well as a non-specific outer membrane rupture may also be potential release pathways for these apoptogenic factors. In this review, we discuss the mechanistic models by which reactive oxygen species and caspases, via structural and conformational changes of membrane lipids and proteins, promote conditions for inner/outer membrane permeabilization, which may be followed by either opening of pores or a rupture of the outer mitochondrial membrane.

Bacteria have been shown to penetrate the root canal obturating materials and influence the periapical tissues. Endotoxin, a component of Gram-negative bacteria, is a potent inflammatory agent and may be able to penetrate obturating materials faster than bacteria. This in vitro study examined the possible penetration of post-prepared canals by endotoxin and bacterial cells derived from mixed bacterial communities. Results showed that both bacteria and endotoxin were able to penetrate the obturating materials in post-prepared canals; however, endotoxin penetration was faster than bacterial. If one speculates that a similar sequence of events occurs clinically, then such a rapid penetration of endotoxin could lead to an early periapical reaction, with subsequent treatment failure and need for retreatment or periapical surgery. The need for an immediate and proper coronal restoration after root canal treatment is therefore reinforced.

For this purpose two decadeoxynucleotides, d(G-G-G-A-A-T-T-C-T-T) (Ia) and d(A-A-G-A-A-T-T-C-C-C) (Ib) were synthesized. The duplex Ia X Ib is cleaved by EcoRI preferentially in the dA-rich strand (approximately 10 times over the dG-rich strand). The individual nucleotides Ia and Ib are also cleaved by EcoRI, Ib at a higher rate than Ia and both at a lower rate than Ia X Ib. The temperature dependence of the reaction rate shows that only double-stranded oligodeoxynucleotides are substrates for the EcoRI endonuclease. We have, furthermore, synthesized oligomers of d(G-G-A-A-T-T-C-C), which contain two, three and four EcoRI sites, respectively. These oligodeoxynucleotides are preferentially cleaved at the sites next to the 5' end, where the recognition site is only flanked by one dG X dC base pair, in contrast to the other sites which are flanked by three such pairs. These data indicate that sequences adjacent to the recognition site influence the rate of cleavage: dA X dT base pairs enhance and dG X dC base pairs slow down the hydrolytic activity of the EcoRI endonuclease.

To gain a comprehensive view of the coagulation/fibrinolytic balance in SSc, a number of haemostatic and fibrinolytic variables were measured in 26 SSc patients (11 limited, 15 diffuse) and in 22 control subjects. Of the coagulation activation markers, the mean plasma level of prothrombin fragment 1 + 2 (F1 + 2), but not of thrombin-antithrombin complexes (TAT), was higher in SSc patients than in controls (P < 0.001). Plasma levels of fibrin split product D-dimer (DD), fibrinogen (FNG) and von Willebrand factor (vWF) were higher amongst patients than controls (P < 0.001). vWF and FNG levels were positively correlated (P < 0.001). Mean levels of DD and vWF were more elevated in patients with diffuse than limited disease (P = 0.001 and P = 0.04, respectively). On the fibrinolytic side, defective tissue plasminogen activator (tPA) release (venous occlusion test, stimulated level < basal level) was noted in 46% (12/26) of SSc patients, but only in 4% (1/22) of controls. Patients had higher mean levels of tPA inhibitor (PAI) than controls (P < 0.001), levels being more elevated amongst patients with diffuse than limited disease (P = 0.01). An abnormally high lipoprotein (a) [Lp(a)] level was found in 9% (2/20) of control subjects, but in 30% (8/26) of SSc patients (P = 0.04) where it clustered with fibrinolytic defects. Altogether, these data suggest that patients with SSc are in a hypercoagulable state characterized by elevated plasma levels of FNG and vWF, by a dual hypofibrinolytic pattern (defective tPA release and elevated PAI), and by increased thrombin generation with enhanced fibrin formation. Higher levels of vWF, DD and PAI in patients with diffuse disease are consistent with more extensive (micro)vascular involvement, although no causal relationship can be inferred. The lack of a parallel increase of TAT with F1 + 2, in the presence of normal levels of antithrombin III (ATIII), indirectly suggests an impairment of the heparan sulphate-ATIII system which would favour thrombin generation. Since thrombin may act as a mitogen for fibroblasts, may upregulate vWF, PAI and endothelin production by endothelial cells, and may promote fibrin deposition on the vessel wall leading to worsening of microvascular occlusions, limitation of thrombin generation, besides fibrinolytic enhancement, could represent a possible coadjuvant interventional strategy.

However, there is little information about the substrate recognition patterns in vivo. The prediction and characterization of proteolytic cleavage sites in natural substrates could be useful for uncovering these structural relationships. RESULTS PEST-like sequences rich in the amino acids Ser (S), Thr (T), Pro (P), Glu or Asp (E/D), including Asn (N) and Gln (Q) are adjacent structural/sequential elements in the majority of cleavage site regions of the natural caspase substrates described in the literature, supporting its possible implication in the substrate selection by caspases. We developed CaSPredictor, a software which incorporated a PEST-like index and the position-dependent amino acid matrices for prediction of caspase cleavage sites in individual proteins and protein datasets. The program predicted successfully 81% (111/137) of the cleavage sites in experimentally verified caspase substrates not annotated in its internal data file. Its accuracy and confidence was estimated as 80% using ROC methodology. The program was much more efficient in predicting caspase substrates when compared with PeptideCutter and PEPS software. Finally, the program detected potential cleavage sites in the primary sequences of 1644 proteins in a dataset containing 9986 protein entries.

At low concentrations of spermine and spermidine, the rate of DNA cleavage by EcoRI is increased, while high concentrations of spermine as well as of spermidine are inhibitory. These phenomena are also observed with other restriction endonucleases. They are, therefore, probably due to the interaction of the polyamines with the DNA. Putrescine does not have such an effect within the concentration range investigated. Remarkably, low concentrations of spermine and spermidine very efficiently suppress EcoRI activity. An inhibition of the EcoRI-catalyzed cleavage of DNA is also observed with NS1 and NS2, an effect that can be mimicked with other basic proteins that interact with DNA. The results are discussed in terms of the mechanism of restriction in vivo.

Upon transformation of this plasmid into E. coli and infection with bacteriophage f1 single stranded plasmids are produced which can be used for sequencing and site directed mutagenesis. Using this single stranded DNA and synthetic oligodeoxynucleotides we have introduced point mutations at defined positions of the EcoRI gene. Since in pRIF309+ the EcoRI gene is under the control of the pL-promoter, high level expression of the mutated EcoRI gene could be obtained upon induction. Mutant EcoRI enzymes were purified to homogeneity and characterized in structural and functional terms. Our results demonstrate that the Glu 111----Gln, Glu 144----Gln and Arg 145----Lys -mutants adopt a very similar conformation as the wild type enzyme, but have by two orders of magnitude smaller specific activities than the wild type enzyme, mainly due to a reduction of the Vmax-value.

The two plasmid DNAs with the EcoRI sites 318 and 96 base pairs apart are cut in a distributive fashion, while the oligonucleotide with the EcoRI sites 8 base pairs apart is cut in a partially processive manner. It is concluded that a linear diffusion of the EcoRI endonuclease on its substrate across long stretches of DNA is not likely to be operative during the recognition process. Microscopic dissociation-reassociation processes, however, increase the probability of the enzyme to attack further sites located in the immediate vicinity of a given site.

This outbreak occurred on Santiago Island (Republic of Cabo Verde), a region where malaria is hypoendemic and controlled, and thus the population is considered non-immune. Blood samples were collected from the inhabitants over 1 month and during cross-sectional surveys in the following year. The presence and nature of the parasites was determined by PCR. Plasmodium falciparum was the only species detected. Genetic analysis revealed that the circulating parasites were genetically homogeneous, and probably clonal. Gametocytes were found throughout this period. Our data suggest that this represented a focal outbreak, resulting in the infection of at least 40% of the villagers with a clonal parasite line. Thus, P. falciparum infections can persist for at least 1 year in a substantial proportion (10%) of the hosts. Implications for malaria control and the interpretation of epidemiological data are discussed.

To evaluate the antioxidant susceptibility of some of the above pathways, probucol (500 mg/d orally, a cholesterol lowering agent bearing antioxidant properties) was administered for a three week period to 14 subjects with aPL and to seven healthy controls. At baseline aPL participants showed higher plasma levels of vWF (P = 0.006), ET-1 (P = 0.0002) and enhanced urinary excretion of 11-dehydro-thromboxane-B2 (TXB2) (P = 0.0004), F2-isoprostanes (marker of lipid peroxidation) (P = 0.02) and albumin (P = 0.04) than controls. In the aPL group baseline IgG anticardiolipin (aCL) titre positively related with urinary TXB2 (r2 = 0.43, P = 0.01) and inversely with urinary NOx (r2 = -0.6, P = 0.005) whereas urinary NOx and TXB2 were negatively correlated (r2 = -0.42, P = 0.01). After the treatment period significant decreases from baseline values were noted for PAI (P = 0.01), ET-1 (P = 0.006), TXB2 (P = 0.02), F2-isoprostanes (P = 0.01) and albuminuria (P = 0.01) in aPL participants but not in controls. These pilot data support oxidative sensitive mechanisms and a potential role for antioxidant treatment in the pathogenesis of aPL induced vasculopathy.

Biochemistry 1995;34:11191-7. [PMID: 7669777 DOI: 10.1021/bi00035a026] [Citation(s) in RCA: 35] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 01/26/2023] Abstract In order to investigate the accuracy of the EcoRV restriction endonuclease, we have synthesized a set of double-stranded oligodeoxynucleotides comprising the canonical recognition sequence, the 9 star sequences (i.e., sequences deviating by one base pair from the canonical sequence), and the 18 mismatch sequences (i.e. sequences deviating by one base from the canonical sequence). For each individual single strand of all these 28 substrates we have measured the rate of phosphodiester bond cleavage under normal buffer conditions. Double-strand cleavage of star substrates is at least 5 orders of magnitude slower than cleavage of the canonical substrate. In contrast, most of the mismatch substrates are accepted more readily. In the absence of the essential cofactor Mg2+, EcoRV binds weakly but equally to the canonical and degenerate substrates, (i.e., KDiss is in the micromolar range). However, the inactive catalytic site mutant D90A in the presence of Mg2+ binds the canonical substrate 1-2 orders of magnitude better than degenerate substrates. Therefore, the EcoRV endonuclease needs the essential cofactor Mg2+ to create thermodynamic discrimination between degenerate and canonical sites. But the main discrimination is kinetically controlled and takes place during cleavage. While in the canonical substrate both single strands are cleaved with an equal velocity, in all other substrates one single strand is cleaved faster than the other one, resulting in a dissociation of the enzyme from the DNA between the two cuts. In vivo this may lead to a repair of the erroneous cleavage site by DNA ligases.(ABSTRACT TRUNCATED AT 250 WORDS) Collapse Key Words Collapse MESH Headings Base Composition Base Sequence Binding Sites Binding, Competitive DNA Repair Deoxyribonucleases, Type II Site-Specific/metabolism In Vitro Techniques Kinetics Magnesium/metabolism Molecular Sequence Data Oligodeoxyribonucleotides/chemistry Oligodeoxyribonucleotides/genetics Oligodeoxyribonucleotides/metabolism Substrate Specificity Collapse Grants Collapse		30	35

Mutational analysis of the function of Gln115 in the EcoRI restriction endonuclease, a critical amino acid for recognition of the inner thymidine residue in the sequence -GAATTC- and for coupling specific DNA binding to catalysis. J Mol Biol 1993;229:221-34. [PMID: 8421302 DOI: 10.1006/jmbi.1993.1019] [Citation(s) in RCA: 34] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 01/30/2023] Abstract The Gln115 residue of the EcoRI restriction endonuclease has been proposed to form a hydrophobic contact to the methyl group of the inner thymidine of the EcoRI recognition sequence -GAATTC- and to be involved in intramolecular hydrogen bonds to the mainchain at positions 140 and 143 as well as to the side-chain of Asn173. We have exchanged Gln115 for Ala and Glu by site-directed mutagenesis and analysed the purified mutant proteins (Q115A and Q115E) biochemically and physico-chemically. Q115A and Q115E have the same secondary structure composition as wild-type EcoRI but are less stable towards thermal denaturation than the wild-type enzyme. In contrast to wild-type EcoRI the mutant proteins show a biphasic denaturation profile under alkaline pH, presumably because the amino acid exchange labilizes one part of the molecule, which unfolds before the rest of the protein is denatured. Q115A is catalytically inactive under normal buffer conditions, in part due to a diminished affinity towards DNA. At low ionic strength and alkaline pH, as well as in the presence of Mn2+, i.e. under conditions where wild-type EcoRI shows a relaxed specificity, Q115A is active, however not as much as wild-type EcoRI. Under these conditions it cleaves the canonical sequence -GAATTC- with the same kcat/Km value as the sequence -GAAUTC-, which differs from the former sequence by a single methyl group, while wild-type EcoRI shows a tenfold lower kcat/Km for cleavage of -GAAUTC- than for -GAATTC-. Binding experiments, carried out in the absence of Mg2+, demonstrate that Q115A has a similar affinity towards -GAATTC- as to -GAAUTC-, while wild-type EcoRI binds to -GAATTC- with a tenfold preference over -GAAUTC-. On the basis of these thermodynamic and kinetic results it can be concluded that the hydrophobic contact between the gamma-methylene group of Gln115 and the methyl group of the inner thymidine contributes about 3 kJ/mol (0.7 kcal/mol) to the energy of interaction, both in the ground and the transition state. Q115E is catalytically inactive under normal buffer conditions, but becomes active at low ionic strength or in the presence of Mn2+. Different from Q115A, Q115E is inactive at alkaline pH and its DNA binding affinity is highest at acidic pH.(ABSTRACT TRUNCATED AT 400 WORDS) Collapse Key Words Collapse MESH Headings Base Sequence Binding Sites DNA-Binding Proteins/chemistry Deoxyribonuclease EcoRI/chemistry Glutamine Models, Chemical Models, Molecular Molecular Sequence Data Mutagenesis Thymidine/metabolism Collapse Grants Collapse		32	34
