Abstract
We present the complete sequence of the nuclear-encoded small-ribosomal-subunit RNA inferred from the cloned gene sequence of the dinoflagellate Prorocentrum micans. The dinoflagellate 17S rRNA sequence of 1798 nucleotides is contained in a family of 200 tandemly repeated genes per haploid genome. A tentative model of the secondary structure of P. micans 17S rRNA is presented. This sequence is compared with the small-ribosomal-subunit rRNA of Xenopus laevis (Animalia), Saccharomyces cerevisiae (Fungi), Zea mays (Planta), Dictyostelium discoideum (Protoctista), and Halobacterium volcanii (Monera). Although the secondary structure of the dinoflagellate 17S rRNA presents most of the eukaryotic characteristics, it contains sufficient archaeobacterial-like structural features to reinforce the view that dinoflagellates branch off very early from the eukaryotic lineage.

Abstract
Since poly-ADP ribose was discovered over 40 years ago, there has been significant progress in research into the biology of mono- and poly-ADP-ribosylation reactions. During the last decade, it became clear that ADP-ribosylation reactions play important roles in a wide range of physiological and pathophysiological processes, including inter- and intracellular signaling, transcriptional regulation, DNA repair pathways and maintenance of genomic stability, telomere dynamics, cell differentiation and proliferation, and necrosis and apoptosis. ADP-ribosylation reactions are phylogenetically ancient and can be classified into four major groups: mono-ADP-ribosylation, poly-ADP-ribosylation, ADP-ribose cyclization, and formation of O-acetyl-ADP-ribose. In the human genome, more than 30 different genes coding for enzymes associated with distinct ADP-ribosylation activities have been identified. This review highlights the recent advances in the rapidly growing field of nuclear mono-ADP-ribosylation and poly-ADP-ribosylation reactions and the distinct ADP-ribosylating enzyme families involved in these processes, including the proposed family of novel poly-ADP-ribose polymerase-like mono-ADP-ribose transferases and the potential mono-ADP-ribosylation activities of the sirtuin family of NAD(+)-dependent histone deacetylases. A special focus is placed on the known roles of distinct mono- and poly-ADP-ribosylation reactions in physiological processes, such as mitosis, cellular differentiation and proliferation, telomere dynamics, and aging, as well as "programmed necrosis" (i.e., high-mobility-group protein B1 release) and apoptosis (i.e., apoptosis-inducing factor shuttling). The proposed molecular mechanisms involved in these processes, such as signaling, chromatin modification (i.e., "histone code"), and remodeling of chromatin structure (i.e., DNA damage response, transcriptional regulation, and insulator function), are described. A potential cross talk between nuclear ADP-ribosylation processes and other NAD(+)-dependent pathways is discussed.

Abstract
Semen cryopreservation is widely used in clinical medicine, agriculture, aquaculture and biomedical research, but it is an inefficient technique that induces extensive cytoplasmic damage and loss of fertilising ability. Whether any genetic damage (i.e. DNA strand breakage or mutation) is also induced is still unclear. However, previous data has indicated that this is likely. The present study was designed to explore this possibility further by using inhibitors of the DNA repair system to block DNA repair in embryos derived from cryopreserved spermatozoa. If cryopreservation causes strand breaks in sperm DNA it might be expected that inhibition of a repair enzyme such as poly(ADP-ribose) polymerase (PARP) would enhance any such negative effect of cryopreservation. To check this hypothesis 3-aminobenzamide (3-AB) was used as an inhibitor of PARP. Weather loach (Misgurnus fossilis) eggs were fertilised using cryopreserved as well as fresh spermatozoa. Embryos derived from cryopreserved spermatozoa were exposed to 10 mM 3-AB for 2 h after fertilisation. The experiments were carried out using 43,544 embryos from 5 females and 10 males. Embryo survival was evaluated at different stages until the hatching stage. Sperm cryopreservation significantly decreased embryo survival (53.6+/-2.79% compared to 76.97+/-2.79% of control; P<0.01). The addition of 3-AB to the medium with embryos derived from cryopreserved sperm further decreased embryo survival from 53.6+/-2.79% to 46.1+/-2.79% (P<0.01) whereas there was no adverse effect of 3-AB exposed embryos derived from fresh sperm (76.97+/-2.79% of control compared to 74.8+/-2.79% of control+3-AB). The effect of 3-AB provides indirect evidence that cryopreservation might induce instability in sperm DNA, and that such damage can be repaired by the oocyte repair system after fertilisation.

Abstract
Poly(ADP-ribosylation) is a post-translational modification of nuclear proteins typical of most eukaryotic cells. This process participates in DNA replication and repair and is mainly regulated by two enzymes, poly(ADP-ribose) polymerase, which is responsible for the synthesis of polymers of ADP-ribose, and poly(ADP-ribose) glycohydrolase, which performs polymer degradation. The aim of this work was to investigate in the cockroach Periplaneta americana L. (Blattaria: Blattidae) the behaviour of poly(ADP-ribosylation). In particular, we addressed: (i) the possible modulation of poly(ADP-ribosylation) during the embryonic development; (ii) the expression of poly(ADP-ribose) polymerase and glycohydrolase in different tissues; and (iii) the role of poly(ADP-ribosylation) during spermatogenesis. In this work we demonstrated that: (i) as revealed by specific biochemical assays, active poly(ADP-ribose) polymerase and glycohydrolase are present exclusively in P. americana embryos at early stages of development; (ii) an activity carrying out poly(ADP-ribose) synthesis was found in extracts from testes; and (iii) the synthesis of poly(ADP-ribose) occurs preferentially in differentiating spermatids/spermatozoa. Collectively, our results indicate that the poly(ADP-ribosylation) process in P. americana, which is a hemimetabolous insect, displays catalytical and structural features similar to those described in the holometabolous insects and in mammalian cells. Furthermore, this process appears to be modulated during embryonic development and spermatogenesis.

Abstract
Poly(ADP-ribosyl)ation is a post-translational modification of proteins. During this process, molecules of ADP-ribose are added successively on to acceptor proteins to form branched polymers. This modification is transient but very extensive in vivo, as polymer chains can reach more than 200 units on protein acceptors. The existence of the poly(ADP-ribose) polymer was first reported nearly 40 years ago. Since then, the importance of poly(ADP-ribose) synthesis has been established in many cellular processes. However, a clear and unified picture of the physiological role of poly(ADP-ribosyl)ation still remains to be established. The total dependence of poly(ADP-ribose) synthesis on DNA strand breaks strongly suggests that this post-translational modification is involved in the metabolism of nucleic acids. This view is also supported by the identification of direct protein-protein interactions involving poly(ADP-ribose) polymerase (113 kDa PARP), an enzyme catalysing the formation of poly(ADP-ribose), and key effectors of DNA repair, replication and transcription reactions. The presence of PARP in these multiprotein complexes, in addition to the actual poly(ADP-ribosyl)ation of some components of these complexes, clearly supports an important role for poly(ADP-ribosyl)ation reactions in DNA transactions. Accordingly, inhibition of poly(ADP-ribose) synthesis by any of several approaches and the analysis of PARP-deficient cells has revealed that the absence of poly(ADP-ribosyl)ation strongly affects DNA metabolism, most notably DNA repair. The recent identification of new poly(ADP-ribosyl)ating enzymes with distinct (non-standard) structures in eukaryotes and archaea has revealed a novel level of complexity in the regulation of poly(ADP-ribose) metabolism.

Abstract
There are one million molecules of poly(ADP-ribose) polymerase (PARP) in mammalian cell nuclei and the enzyme is found in most eukaryotes, with the notable exception of yeasts. In response to DNA damage caused by ionizing radiation or alkylating agents, PARP binds to strand interruptions in DNA and undergoes rapid automodification with synthesis of long branched polymers of highly negatively charged poly(ADP-ribose). DNA repair occurs after dissociation of modified PARP from DNA strand breaks. Biochemical data with enzyme-depleted extracts and studies of enzyme-deficient mice show that PARP does not participate directly in DNA repair. Possible roles for poly(ADP-ribose) synthesis are discussed.

Abstract
Sequence similarities between the enzymatic region of poly-ADP-ribose polymerase and the corresponding region of mono-ADP-ribosylating bacterial toxins suggest similarities in active site structure and catalytic mechanism. Glu988 of the human polymerase aligns with the catalytic glutamic acid of the toxins, and replacement of this residue with Gln, Asp, or Ala caused major reductions in synthesis of enzyme-linked poly-ADP-ribose. Replacement of any of 3 other nearby Glu residues had little effect. The Glu988 mutations produced similar changes in activity in the carboxyl-terminal 40-kDa catalytic fragment fused to maltose-binding protein: E988Q and E988A reduced polymer elongation > 2000-fold, and E988D approximately 20-fold. Smaller changes were seen in chain initiation. The mutations had little effect on the Km of NAD, indicating a predominantly catalytic function for Glu988. The results support the concept of similar active sites of the polymerase and the ADP-ribosylating toxins. Glu988 may function in polymer elongation similarly to the toxins' active site glutamate, as a general base to activate the attacking nucleophile (in the case of the polymerase, the 2'-OH of the terminal adenosine group of a nascent poly-ADP-ribose chain).

Abstract
Poly ADP-ribosylation is a post-translational modification of protein structure and function that occurs in the nucleus of most eukaryotic cells. Although its function has not been fully elucidated it is thought to have a role in the processing DNA strand breaks. Poly(ADP-ribose) polymerase, a highly conserved enzyme, is well studied in animal cell systems but is less well characterised in plants. Our present understanding of mono and poly ADP-ribosylation reactions in plants is reviewed in this article.

Abstract
The coding sequence for human poly(ADP-ribose) polymerase was expressed inducibly in Saccharomyces cerevisiae from a low-copy-number plasmid vector. Cell free extracts of induced cells had poly(ADP-ribose) polymerase activity when assayed under standard conditions; activity could not be detected in noninduced cell extracts. Induced cells formed poly(ADP-ribose) in vivo, and levels of these polymers increased when cells were treated with the alkylating agent N-methyl-N'-nitro-N- nitrosoguanidine (MNNG). The cytotoxicity of this agent was increased in induced cells, and in vivo labelling with [3H]adenine further decreased their viability. Increased levels of poly(ADP-ribose) found in cells treated with the alkylating agent were not accompanied by lowering of the NAD concentration.

Abstract
Poly(ADP-ribose) polymerase cDNAs have been isolated from different classes of animals. Cloning of genes from lower eukaryotes has allowed us to investigate directly the biological functions of poly(ADP-ribosyl)ation in vivo. The conservation of specific regions among mammals, chicken, Xenopus laevis, and Drosophila melanogaster reveals the essential structural elements required for recognition of breaks in DNA and for catalytic activity. Cys, His and basic residues in the zinc-finger consensus region are conserved. The carboxyl terminal region corresponding to an NAD-binding domain is strongly conserved. The dinucleotide-binding consensus sequence and beta 1-alpha A-beta 2, Rossmann fold structure, and beta-sheet structures are completely conserved from mammals to insect. In Drosophila, a putative leucine-zipper motif has been identified, and other poly(ADP-ribose) polymerases also contain an alpha-helical, amphipathic structure in the auto-modification domain. In this article, we review the recent structural analyses of the functional domains of poly(ADP-ribose) polymerase in phylogenetically divergent species, and discuss the implications of structural conservation for its biological functions.

Abstract
Post-translational modification of nuclear proteins with poly(ADP-ribose) modules chromatin structure and may be required for DNA processing events such as replication, repair and transcription. The polymer-catabolizing enzyme, poly(ADP-ribose) glycohydrolase, is crucial for the regulation of polymer metabolism and the reversibility of the protein modification. Previous reports have shown that glycohydrolase digests poly(ADP-ribose) via an exoglycosidic mechanism progressing from the protein-distal end of the polymer. Using two independent approaches, we investigated the possibility that poly(ADP-ribose) glycohydrolase also engages in endoglycosidic cleavage of polymers. First, partial glycohydrolase digestion of protein-bound poly(ADP-ribose) led to the production of protein-free oligomers of ADP-ribose. Second, partial glycohydrolase digestion of a fixed number of protein-free poly(ADP-ribose) polymers resulted in a transient increase in the absolute number of polymers while polymer size continuously decreased. Furthermore, endoglycosidic activity produced linear polymers from branched polymers although branch points themselves were not a preferential target of cleavage. From these data, we propose a mechanism whereby poly(ADP-ribose) glycohydrolase degrades polymers in three distinct phases; (a) endoglycosidic cleavage, (b) endoglycosidic cleavage plus exoglycosidic, processive degradation, (c) exoglycosidic, distributive degradation.

Abstract
The abundant nuclear enzyme poly(ADP-ribose) polymerase catalyses the synthesis of poly(ADP-ribose) from nicotinamide adenine dinucleotide (NAD+). This protein has an N-terminal DNA-binding domain containing two zinc-fingers, which is linked to the C-terminal NAD(+)-binding domain by a short region containing several glutamic acid residues that are sites of auto-poly(ADP-ribosyl)ation. The intracellular production of poly(ADP-ribose) is induced by agents that generate strand interruptions in DNA. The branched homopolymer chains may attain a size of 200-300 residues but are rapidly degraded after synthesis. The function of poly(ADP-ribose) synthesis is not clear, although it seems to be required for DNA repair. Here we describe a human cell-free system that enables the role of poly(ADP-ribose) synthesis in DNA repair to be characterized. The results indicate that unmodified polymerase molecules bind tightly to DNA strand breaks; auto-poly(ADP-ribosyl)ation of the protein then effects its release and allows access to lesions for DNA repair enzymes.

Abstract
Unlike typical eukaryotes, the Dinoflagellate Crypthecodinium cohnii does not contain histones but six major basic, low molecular weight nuclear proteins which represent only 10% of the DNA mass and differ from histones in their electrophoretic and DNA-binding properties. These proteins are resolved in two-dimensional electrophoresis (AUT-PAGE x SDS-PAGE). Three proteins with an apparent molecular mass of 16, 16.5 and 17 kDa (p16, p16.5 and p17) are present in addition to the major 14 kDa basic nuclear component (HCc). HCc itself is resolved in three proteins (alpha, beta and gamma). When the proteins are not reduced with 2-mercaptoethanol before 2D-PAGE, the migration of HCc alpha, beta and gamma is modified in a way which suggests the formation of both inter- and intramolecular disulfide bridges and thus, the presence of at least two cysteines. The amino-acid analysis of HCc proteins resolved in 2D gels confirms that they are lysine-rich. HCc alpha, beta and gamma as well as p16, p16.5 and p17 are removed from isolated chromatin with 0.6 M NaCl, indicating that their affinity for DNA in vivo is lower than that of core histones. Furthermore, in vitro, they bind more tightly to single-stranded than to double-stranded DNA.

Abstract
The sequence of the large subunit ribosomal RNA (LsuRNA) gene of the dinoflagellate Prorocentrum micans has been determined. The inferred rRNA sequence [3408 nucleotides (nt)] is presented in its most probable secondary structure based on compensatory mutations, energy, and conservation criteria. No introns have been found but a hidden break is present in the second variable domain, 690 nt from the 5' end, as judged by agarose gel electrophoresis and primer extension experiments. Prorocentrum micans LsuRNA length and G+C content are close to those of ciliates and yeast. The conserved portions of the molecule (1900 nt) have been aligned with corresponding sequences from various eukaryotes, including five protista, one metaphyta, and three metazoa. An extensive phylogenetic study was performed, comparing two phenetic methods (neighbor joining on difference matrix, and Fitch and Margoliash on Knuc values matrix) and one cladistic (parsimony). The three methods led to similar tree topologies, except for the emergence of yeast that groups with ciliates and dinoflagellates when phenetic methods are used, but emerges later in the most parsimonious tree. This discrepancy was checked by statistical analyses on reduced trees (limited to four species) inferred using parsimony and evolutionary parsimony methods. The data support the phenetic tree topologies and a close relationship between dinoflagellates, ciliates, and yeast.

Abstract
A phylogenetic survey for the poly(ADP-ribose)polymerase has been conducted by analyzing enzyme activity in various organisms and determining the structure of the catalytic peptides by renaturation of functional activities of the enzyme in situ after electrophoresis in denaturing conditions (activity gel). The enzyme is widely distributed in cells from all different classes of vertebrates, from arthropods, mollusks and plant cells but could not be detected in echinoderms, nematodes, platyhelminths, thallophytes (including yeast) and bacteria. The presence on activity gels of a catalytic peptide with Mr = 115,000-120,000 was demonstrated in vertebrates, arthropods and mollusks but no activity bands were recovered in many lower eukaryotes, in plant cells and bacteria. By using an immunological procedure that used an antiserum against homogeneous calf thymus poly(ADP-ribose) polymerase, common immunoreactive peptides were visualized in mammals, avians, reptiles, amphibians and fishes, while lacking in non-vertebrate organisms. Our results indicate that the structure of poly(ADP-ribose) polymerase is conserved down to the mollusks suggesting its important role for DNA metabolism of multicellular organisms.

Abstract
We have studied the poly(ADP-ribosyl)ation of nuclear proteins in situ by examining the incorporation of [3H]NAD-derived ADP-ribose into polymers. We have devised a way to deliver [3H]NAD to cells growing in vitro, and we have determined the kinetics of uptake and incorporation into nuclear proteins using this delivery system. Incorporation into the histone fraction, known acceptors of poly(ADP-ribose), was examined and shown to be sensitive to the poly(ADP-ribose) polymerase inhibitor 3-aminobenzamide. Polyacrylamide gel electrophoresis of 3H-labeled proteins revealed radioactivity associated with known poly(ADP-ribose)-accepting proteins such as poly(ADP-ribose) polymerase and histones. These results were confirmed when we immunoreacted gel-separated proteins with anti-(ADP-ribose) generated in our laboratory.
