Abstract
Deimination (or citrullination) is a post-translational modification catalyzed by a calcium-dependent enzyme family of five peptidylarginine deiminases (PADs). Deimination is involved in physiological processes (cell differentiation, embryogenesis, innate and adaptive immunity, etc.) and in autoimmune diseases (rheumatoid arthritis, multiple sclerosis and lupus), cancers and neurodegenerative diseases. Intermediate filaments (IF) and associated proteins (IFAP) are major substrates of PADs. Here, we focus on the effects of deimination on the polymerization and solubility properties of IF proteins and on the proteolysis and cross-linking of IFAP, to finally expose some features of interest and some limitations of citrullinomes.

Abstract
Protein arginine deiminase type IV (PAD4) is responsible for the posttranslational conversion of peptidylarginine to peptidylcitrulline. Citrullinated protein is the autoantigen in rheumatoid arthritis, and therefore, PAD4 is currently a promising therapeutic target for the disease. Recently, we reported the importance of the furan ring in the structure of PAD4 inhibitors. In this study, the furan ring was incorporated into peptides to act as the "warhead" of the inhibitors for PAD4. IC50 studies showed that the furan-containing peptide-based inhibitors were able to inhibit PAD4 to a better extent than the furan-containing small molecules that were previously reported. The best peptide-based inhibitor inhibited PAD4 reversibly and competitively with an IC50 value of 243.2 ± 2.4 μm. NMR spectroscopy and NMR-restrained molecular dynamic simulations revealed that the peptide-based inhibitor had a random structure. Molecular docking studies showed that the peptide-based inhibitor entered the binding site and interacted with the essential amino acids involved in the catalytic activity. The peptide-based inhibitor could be further developed into a therapeutic drug for rheumatoid arthritis.

Abstract
BACKGROUND Peptidylarginine deiminases (PADs) catalyze deimination (or citrullination), a calcium-dependent post-translational modification involved in several physiological processes and human diseases, such as rheumatoid arthritis and cancer. Deimination of filaggrin (FLG) by PAD1 and PAD3 during the last steps of keratinocyte differentiation is a crucial event for the epidermis function and homeostasis. This allows the complete degradation of FLG, leading to the production of free amino acids and their derivatives that are essential for epidermal photoprotection and moisturizing of the stratum corneum. OBJECTIVE To increase the flux of this catabolic pathway, we searched for activators of PADs. METHODS A large chemical library was screened first in silico and then by using an automated assay based on an indirect colorimetric measurement of recombinant human PAD activity. Potential activators were then confirmed using a recombinant human FLG as a substrate, and secondly after topical application at the surface of three-dimensional reconstructed human epidermis. RESULTS The data obtained after the library screening pointed to xanthine derivatives as potential PAD activators. Among seven xanthine derivatives tested at 50-300μM, caffeine, theobromine and acefylline proved to be the most potent enhancers of in vitro deimination of FLG by PAD1 and PAD3. After topical application of a gel formulation containing 3% acefylline at the surface of reconstructed epidermis, immunoblotting analysis showed an increase in the total amount of deiminated proteins, and confocal microscopy showed an enhanced deimination in the stratum corneum. This demonstrated the activation of PADs in living cells. CONCLUSION As a PAD activator, acefylline will be useful to study the role of deimination and could be proposed to increase or correct the hydration of the cornified layers of the epidermis.

Abstract
BACKGROUND The conversion of arginine into citrulline, termed citrullination, has important consequences for the structure and function of proteins. Studies have found PADI4, an enzyme performing citrullination, to be highly expressed in a variety of malignant tumours and have shown that PADI4 participates in the process of tumorigenesis. However, as citrullinated proteins have not been systematically investigated in tumours, the present study aimed to identify novel citrullinated proteins in tumours by 2-D western blotting (2-D WB). METHODS Two identical two-dimensional electrophoresis (2-DE) gels were prepared using extracts from ECA, H292, HeLa, HEPG2, Lovo, MCF-7, PANC-1, SGC, and SKOV3 tumour cell lines. The expression profiles on a 2-DE gel were trans-blotted to PVDF membranes, and the blots were then probed with an anti-citrulline antibody. By comparing the 2-DE profile with the parallel 2-D WB profile at a global level, protein spots with immuno-signals were collected from the second 2-DE gel and identified using mass spectrometry. Immunoprecipitation was used to verify the expression and citrullination of the targeted proteins in tumour cell lines. RESULTS 2-D WB and mass spectrometry identified citrullinated α-enolase (ENO1), heat shock protein 60 (HSP60), keratin 8 (KRT8), tubulin beta (TUBB), T cell receptor chain and vimentin in these cell lines. Immunoprecipitation analyses verified the expression and citrullination of ENO1, HSP60, KRT8, and TUBB in the total protein lysates of the tumour cell lines. CONCLUSIONS The citrullination of these proteins suggests a new mechanism in the tumorigenic process.

Abstract
Histone arginine methylation is a posttranslational modification linked to the regulation of gene transcription. Unlike other posttranslational modifications, methylation has generally been regarded as stable, and enzymes that demethylate histone arginine residues have not been identified. However, it has recently been shown that human peptidylarginine deiminase 4 (PAD4), a Ca(2+)-dependent enzyme previously known to convert arginine residues to citrulline in histones, can also convert monomethylated arginine residues to citrulline both in vivo and in vitro. Citrullination of histone arginine residues by the enzyme antagonizes methylation by histone arginine methyltransferases and is thus a novel posttranslational modification that regulates the level of histone arginine methylation and gene activity. Here we present the crystal structures of a Ca(2+)-bound PAD4 mutant in complex with three histone N-terminal peptides, each consisting of 10 amino acid residues that include one target arginine residue for the enzyme (H3/Arg-8, H3/Arg-17, and H4/Arg-3). To each histone N-terminal peptide, the enzyme induces a beta-turn-like bent conformation composed of five successive residues at the molecular surface near the active site cleft. The remaining five residues are highly disordered. The enzyme recognizes each peptide through backbone atoms of the peptide with a possible consensus recognition motif. The sequence specificity of the peptide recognized by this enzyme is thought to be fairly broad. These observations provide structural insights into target protein recognition by histone modification enzymes and illustrate how PAD4 can target multiple arginine sites in the histone N-terminal tails.

Abstract
Three types of peptidylarginine deiminase (PAD), which converts a protein arginine residue to a citrulline residue, are widely distributed in animal tissues. Little is known about PAD of hemopoietic cells. We found that PAD activity in human myeloid leukemia HL-60 cells was induced with the granulocyte-inducing agents retinoic acid and dimethyl sulfoxide and with the monocyte-inducing agent 1alpha,25-dihydroxyvitamin D(3). We cloned and characterized a PAD cDNA from retinoic acid-induced cells. The cDNA was 2,238 base pairs long and encoded a 663-amino acid polypeptide. The HL-60 PAD had 50-55% amino acid sequence identities with the three known enzymes and 73% identity with the recently cloned keratinocyte PAD. The recombinant enzyme differs in kinetic properties from the known enzymes. Immunoblotting and Northern blotting with an antiserum against the enzyme and the cDNA, respectively, showed that a protein of approximately 67 kDa increased concomitantly with increase of mRNA of approximately 2.6 kilobases during granulocyte differentiation. During monocyte differentiation the same mRNA and protein increased as in granulocyte differentiation. Neither the enzyme activity nor the protein was found in macrophage-induced cells. These results suggested that expression of the PAD gene is tightly linked to myeloid differentiation.

Abstract
A novel proteinase inhibitor, Lentinus proteinase inhibitor, has been purified from the fruiting bodies of the edible mushroom, Lentinus edodes, by buffer extraction and affinity chromatography on immobilized anhydrotrypsin. The protein simultaneously inhibits bovine beta-trypsin and alpha-chymotrypsin at independent sites, with apparent dissociation constants of 3.5 x 10(-10) M and 4 x 10(-8) M, respectively. The purified protein is eluted as two well-separated peaks on reversed-phase HPLC, one of which is inhibitory-active and the other inactive, and they are interconvertible under folding/unfolding conditions. Among the mammalian and microbial serine proteinases examined, including human enzymes of blood coagulation and fibrinolysis, activated factor XI was inhibited by the Lentinus proteinase inhibitor. Chemical modification studies suggest involvement of one or more arginine residues in the inhibition of trypsin. The complete primary structure composed of 142 amino acids with an acetylated N-terminus was determined by protein analysis. The theoretical molecular mass (15999.2) from the sequence is close to the experimental value of 15999.61 +/- 0.61 determined by mass spectrometry. Although there are no apparently homologous proteinase inhibitors in the protein database, there is a rather striking similarity to the propeptide segment of a microbial serine proteinase, as well as to the N-terminal region of the mature enzyme.

Abstract
A method is described for the direct colorimetric determination of citrulline residues in proteins based on the reaction with diacetylmonoxime in the presence of lower concentrations of sulfuric acid. The reduced sensitivity due to the lower acid concentration was overcome by the addition of ferric chloride which also contributed to the color stabilization. Insoluble proteins or proteins resulting in turbidity can be analyzed following partial hydrolysis of those with enzyme or acid. The molar absorption coefficient (epsilon) for citrulline at 464 nm was 2.8 x 10(4). The method enabled us to determine low levels of protein-bound citrulline which are beyond the limitations of conventional methods using an amino acid analyzer. We determined the citrulline contents in the cornified cells of the epidermis of newborn rats, as well as soybean trypsin inhibitor.

Abstract
Antithrombin, a plasma serpin, is relatively inactive as an inhibitor of the coagulation proteases until it binds to the heparan side chains that line the microvasculature. The binding specifically occurs to a core pentasaccharide present both in the heparans and in their therapeutic derivative heparin. The accompanying conformational change of antithrombin is revealed in a 2.9-A structure of a dimer of latent and active antithrombins, each in complex with the high-affinity pentasaccharide. Inhibitory activation results from a shift in the main sheet of the molecule from a partially six-stranded to a five-stranded form, with extrusion of the reactive center loop to give a more exposed orientation. There is a tilting and elongation of helix D with the formation of a 2-turn helix P between the C and D helices. Concomitant conformational changes at the heparin binding site explain both the initial tight binding of antithrombin to the heparans and the subsequent release of the antithrombin-protease complex into the circulation. The pentasaccharide binds by hydrogen bonding of its sulfates and carboxylates to Arg-129 and Lys-125 in the D-helix, to Arg-46 and Arg-47 in the A-helix, to Lys-114 and Glu-113 in the P-helix, and to Lys-11 and Arg-13 in a cleft formed by the amino terminus. This clear definition of the binding site will provide a structural basis for developing heparin analogues that are more specific toward their intended target antithrombin and therefore less likely to exhibit side effects.

Abstract
This review covers selected methods of isolation and purification of mainly alpha s-casein, beta-casein, kappa-casein, beta-lactoglobulin, and alpha-lactalbumin. Selected methods of alteration of some functional groups of these proteins also were reviewed. Isolation and purification of milk proteins per se are methods of modifying the individual milk proteins. Gram quantities of these proteins can now be purified in a relatively short time using ion-exchange resins. Due to the prominent use of non-food-grade reagents in the procedures for preparation of these milk proteins, individual proteins are not maximally utilized for the manufacture of food/feed and pharmaceutical products. Therefore, intensive research efforts are needed to obviate the problems associated with underutilization of milk proteins.

Abstract
Antithrombin, the principal plasma inhibitor of coagulation proteinases, circulates in a form with low inhibitory activity due to partial insertion of its reactive site loop into the A-beta-sheet of the molecule. Recent crystallographic structures reveal the structural changes that occur when antithrombin is activated by the heparin pentasaccharide, with the exception of the final changes, which take place at the reactive center itself. Here we show that the side chain of the P1 Arg of alpha-antithrombin is only accessible to modification by the enzyme peptidylarginine deiminase on addition of the heparin pentasaccharide, thereby inactivating the inhibitor, whereas the natural P1 His variant, antithrombin Glasgow, is unaffected, indicating that only the P1 Arg becomes accessible. Furthermore, the deimination of P1 Arg converts antithrombin to a form with 4-fold higher affinity for the heparin pentasaccharide, similar to the affinity found for the P1 His variant, due to a lowered dissociation rate constant for the antithrombin-pentasaccharide complex. The results support the proposal that antithrombin circulates in a constrained conformation, which when released, in this study by perturbation of the bonding of P1 Arg to the body of the molecule, allows the reactive site loop to take up the active inhibitory conformation with exposure of the P1 Arg.

Peptidylarginine deiminases, which are commonly found in mammalian cells, catalyze the deimination of protein-bound arginine residues to citrullines. However, very little is known about their substrate requirements and the significance or consequences of this postsynthetic modification. We have explored this reaction in vitro with two known substrates filaggrin and trichohyalin. First, the degree and rate of modification of arginines to citrullines directly correlates with the structural order of the substrate. In filaggrin, which has little structural order, the reaction proceeded rapidly to >95% completion. However, in the highly alpha-helical protein trichohyalin, the reaction proceeded slowly to about 25% and could be forced to a maximum of about 65%. Second, the rate and degree of modification depends on the sequence location of the target arginines. Third, we show by gel electrophoresis, circular dichroism, and fluorescence spectroscopy that the reaction interferes with organized protein structure: the net formation of >/=10% citrulline results in protein denaturation. Cyanate modification of the lysines in model alpha-helix-rich proteins to homocitrullines also results in loss of organized structure. These data suggest that the ureido group on the citrulline formed by the peptidylarginine deiminase enzyme modification functions to unfold proteins due to decrease in net charge, loss of potential ionic bonds, and interference with H bonds.

Abstract
Examination of the properties of Escherichia coli and rabbit muscle D-glyceraldehyde-3-phosphate dehydrogenase (GPDHs) modified by 2,3-butanedione has shown that both tetrameric enzymes are stabilized, on selective modification of arginine residues (probably Arg 231), in an asymmetric state with only two active centers capable of performing the dehydrogenase reaction. The functionally incompetent active centers can be alkylated by iodoacetate or iodoacetamide in the case of E. coli enzyme, but are inaccessible for these reagents in the case of rabbit muscle D-GPDH. These results are consistent with the idea that the two homologous enzymes share common principles of the protein design, but differ somewhat in their active centers geometries. Modification of the arginine procedures marked changes in the shape of the charge transfer complex spectrum in the region of 300-370 nm, suggestive of the alterations in the microenvironment of the nicotinamide ring of NAD(+), although the coenzyme binding characteristics remain largely unaltered. On arginine modification, the enzyme becomes insensitive to the effect of AMP on the kinetic parameters of p-nitrophenyl acetate hydrolysis reaction.

Abstract
The kinetics of the native glycogen phosphorylase b from rabbit skeletal muscle and of the enzyme specifically deiminated by peptidylarginine deiminase have been studied. One arginine residue per phosphorylase b monomer is transformed into citrulline after 3 h of incubation with peptidylarginine deiminase. The maximal velocity of the enzymatic reaction for the modified phosphorylase b is 7-20% higher than that for the native enzyme. Deiminated phosphorylase b, like the native enzyme, shows a positive kinetic cooperativity with respect to glucose-1-phosphate. The affinity of the modified phosphorylase b for the allosteric activator AMP is one order of magnitude higher than that of the native enzyme. Deimination caused a pronounced reduction of the values of [I]0.5 for FMN and glucose, but the sensitivity of the deiminated enzyme to glucose-6-phosphate is much lower than that of the native phosphorylase b. Deiminated phosphorylase b, unlike the native enzyme, shows the positive cooperativity for FMN binding. Deiminated phosphorylase b, unlike the native enzyme, shows less capability to form tetramers in the presence of AMP as compared to the native enzyme.

Abstract
Peptidylarginine deiminase is localized in the cytosol of the luminal and glandular epithelia of the nonpregnant murine uterus and its expression is regulated by sex hormones [Takahara et al., [1989]: J Biol Chem 264, 13361-13368; Takahara et al. [1992]: J Biol Chem 267,520-525]. Here, we demonstrate that changes occur in the enzyme level in the mouse uterus during pregnancy and parturition. After a rapid decrease in enzymatic activity from day 1 to day 5 of pregnancy, the activity sharply increased during the middle stage of pregnancy (day 8 to day 10) and then gradually decreased during late pregnancy. Expression of the enzyme occurred only in the decidual cells that had differentiated from endometrial stroma cells surrounding the implantation site. The immunochemical properties of the enzyme expressed in the decidualized cells was indistinguishable from those in the uterine epithelia. These results suggest that peptidylarginine deiminase has important roles in decidual cells and not just in the epithelia of the nonpregnant uterus. Moreover, the level of enzyme activity increased slightly just before parturition (day 17), and then decreased during the 12 h period after parturition. The tissue localization of the enzyme expressed around the time of parturition changed from decidua to the luminal and glandular epithelia. Semiquantitative analyses of the enzyme mRNA content in the pregnant uteri showed a remarkable increase from day 7 leading to the onset of the enzyme synthesis in the decidual cells. After reaching the maximal level at day 12, small peaks in the mRNA level were observed at two times during late pregnancy. Since these serial changes in the mRNA level did not correlate with changes in sex hormones, the expression of decidual peptidylarginine deiminase seemed to be controlled by factors other than sex hormones.

Abstract
Peptidylarginine deiminase is a protein-modulating enzyme which converts the arginine residues in proteins to citrulline residues. This study describes the complete primary structure of mouse peptidylarginine deiminase, which was deduced from nucleotide sequence analysis of cDNA clones plus proteochemical analysis of the purified enzyme. The composite cDNA sequence contained a 5' untranslated region of 7 bases, an open reading frame of 2019 bases that encoded 673 amino acids, a 3' untranslated region of 2662 bases, and part of a poly(A) tail. The N-terminal and C-terminal sequences of the enzyme matched the sequences deduced from nucleotide analysis. Furthermore, we determined that the N-terminal sequence was N alpha-acetyl-Met-Gln-, a sequence which has never previously been reported among N alpha-acetyl-Met proteins. The Arg 352 of the enzyme was converted to a citrulline residue and the potential Asn-linked glycosylation site (Asn542-Glu543-Ser544) had no carbohydrate moiety. Thus, mouse peptidylarginine deiminase consists of 673 amino acids with a molecular mass of 76,260. Mouse peptidylarginine deiminase mRNA has two AU-rich structures in the 3' untranslated region which exhibit a high degree of similarity to those in lymphokine, cytokine and proto-oncogene mRNA species. Since the rat enzyme (previously reported) does not possess these characteristic structures, we compared the levels of enzyme activity and mRNA in the mouse and rat uterus at four defined phases of the estrous cycle. The degradation of peptidylarginine deiminase and its mRNA proceeded significantly faster in the mouse than in the rat. We speculate that the unusual structure of the mouse enzyme and its mRNA be involved in this species-specific rapid degradation.

Abstract
The primary and secondary specificities and mode of action of the muscle-type protein-arginine deiminase (PAD) were investigated using various derivatives of Arg and its homologues, as well as Arg-containing peptides by quantitative analyses of the reaction products on reverse-phase HPLC. The enzyme converted benzoyl-D-Arg-p-nitroanilide into its citrulline derivative at 18% of the rate of the L-isomer, while the D-Arg residues in peptides were not deiminated to a significant extent. This suggests that PAD does not have strict stereospecificity and it is dependent on the structure of the residues or groups on both sides of the target Arg residue. In contrast, the benzoyl-/-ethyl ester derivatives of homoarginine, alpha-amino-beta-guanidino-propionic acid, canavanine, and NG-methyl-Arg, exhibited poor PAD susceptibility, suggesting that the length and nature of the arm as exactly three CH2 groups, and the integrity of the guanidyl group are quite strict specificity determinants. The enzyme action on Arg residues in peptides depends greatly on their position in the sequence, and on the nature of the neighboring residues. For example, deimination of Arg residues situated at positions 1-3 from the NH2-terminus, except for those preceded by a carbobenzoxy- or benzoyl-group, were in most cases very slow, whereas those at the COOH-terminus were deiminated relatively faster. A single Arg residue sandwiched between two Pro residues was not deiminated at all, while a pair of Arg residues between two Pro were deiminated moderately. Consequently, PAD exhibited a variety of modes of action on more than one Arg residues in the peptides tested. The results suggest the applicability of PAD, albeit quite limited, for selective modification of certain Arg residues in peptides and proteins by appropriately controlling reaction time and several other parameters. The PAD's mode of action was compared with those of three Arg-bond cleaving proteases.

Abstract
Insulin and type I insulin-like growth factor (IGF-I) suppressed growth hormone (GH) expression followed by the induction of prolactin (PRL) biosynthesis in MtT/S cells cultured with normal sera. Insulin also increased the peptidylarginine deiminase activity in a dose-dependent manner. The increase was detectable at 1 ng/ml and reached a maximum (about 16-fold higher than the control) at 1 micrograms/ml. IGF-I showed similar but less prominent effects. The enzyme activity started to increase by 15 hr after the addition of insulin (500 ng/ml), and reached a plateau level at 48 hr. There were concurrent increases in the enzyme mRNA level, enzyme biosynthesis, and enzyme protein contents detected by Northern blot hybridization, [35S]-amino-acid incorporation, and Western immunoblot analysis, respectively. Two-color immunofluorescence staining at 1 day after the insulin addition detected a small number of peptidylarginine-deiminase-positive cells (about 1% of the total cells) which were also GH-positive. The enzyme-positive cells increased to 12% on day 2 and to 24-26% on days 4-6. PRL-positive cells first appeared in the enzyme-positive cell population on day 2, and PRL-positive, enzyme-negative cells appeared later. These results suggest that peptidylarginine deiminase expression increases in association with the hormone switching in MtT/S cells. When the cells were cultured in a steroid-depleted medium, insulin failed to increase the enzyme activity. The insulin action could be specifically restored by estrogen, indicating estrogen-insulin synergism in regulation of the enzyme expression.

Abstract
Enzymic modification with peptidylarginine deiminase (EC 3.5.3.15) enabled five out of six arginyl residues in alpha s1-casein to be converted to citrullyl residues, only the N-terminal arginyl residue remaining unaffected. An increase in the net negative charge was confirmed by PAGE. The isoelectric point was decreased from 4.46 for the intact alpha s1-casein to 4.30 for the deiminated type, while simultaneously lowering the acid-precipitation starting point from pH 5.17 to pH 4.62. The deiminated alpha s1-casein self-associated less in the absence of Ca and was less Ca-sensitive than the native type, although its Ca-binding ability was slightly enhanced. In the presence of 25 mM-CaCl2 and kappa-casein, Ca-induced precipitation of alpha s1-casein did not occur, the solution of the mixture remaining transparent. Deimination of alpha s1-casein resulted in altering its characteristics, possibly by interfering with interactions through hydrophobicity and/or hydrogen bonding. The positive charge of the arginyl residues might play an important role in casein micelle formation.

Abstract
A Nonidet P-40 extract of growth hormone-producing rat pituitary MtT/S cells was found to contain peptidylarginine deiminase (EC 3.5.3.15), which was indistinguishable from an enzyme preparation from rat muscle in Western immunoblotting and immunoprecipitation. This enzyme was immunocytochemically detected in the cytoplasm but was not secreted into the medium during the cultivation. When the cells were cultured for 2 days with various concentrations of 17 beta-estradiol (E2), the enzyme activity increased in a dose-dependent manner, reaching a maximum level (four- to fivefold higher than control) at about 10(-9) M. This increase in the enzyme activity was evident by 14 hr of culture and became relatively stable after 24 hr. It correlated well with the increase in the amount of the muscle type enzyme per cell as analyzed by Western immunoblotting. Estriol and a synthetic estrogen, diethylstilbestrol, also increased the enzyme activity, whereas testosterone, progesterone, and corticosterone were without effect. An antiestrogen, tamoxifen, which by itself was inactive, partially suppressed the effect of E2. Exposure of MtT/S cells for 14 hr to E2 increased incorporation of 35S-labeled amino acids into the immunoprecipitable peptidylarginine deiminase. This increase was dependent on the concentration of E2, attaining a maximum level (about tenfold higher than the control) at about 10(-9) M. These results indicate that estrogen effects the increase in peptidylarginine deiminase content in the pituitary cells by stimulating enzyme synthesis.
