Abstract
Ten marine species, including different crabs, bivalve molluscs, and fish intestines were selected to screen the natural antimicrobial protein or peptide as they are enriched with various microorganisms. The crude extract from Varuna litterata, a marine crab which is used as a raw material in the preparation of pickled crabs in Chaoshan area of China, was proved to have a potent bacteriostatic effect against gram-negative bacterium (Escherichia coli) and gram-positive bacterium(Staphylococcus aureus) compared with other marine species. The crude proteins of Varunalitterata were salted-out for preliminary purification and further purified by gel filtration (Sephadex G-150) or anion exchange (DEAE-cellulose 52) chromatographic column. An increase in the antimicrobial activity was noted with the increase in the purity level of the protein. A relatively pure protein was eventually obtained, which was determined to be belonging to the hemocyanin family based on the mass spectrometric data analysis. The purified proteins solution (1 mg/ml) from Varuna litterata exhibited similar antimicrobial activity to that of gentamycin sulfate (0.2 mg/ml), which were relatively stable in a certain pH or temperature range. A structure-activity relationship of the purified hemocyanin was determined based on the interaction of hemocyanin and different chromatographic medium, which revealed that the integrated hexamers played a remarkable role in its bacteriostatic activity. Moreover, the phenoloxidase activity of hemocyanin from Varuna litterata was found as the underlying cause of its antimicrobial potential.

Abstract
In this study, an improved, rapid, high yield synthesis of N,N'-4,4'-bis(benzyl-2-boronic acid)-bipyridinium dibromide (o-BBV) is described. The obtained o-BVV is applied in a two-component saccharide sensing system (complex) where it serves as a fluorescence quencher and a saccharide receptor. This system was applied to different natural oligosaccharides isolated from molluscan Rapana venosa (RvH1-a) and arthropodan Carcinus aestuarii (CaeH) hemocyanins (Hcs) and cyclodextrins (CDs). The carbohydrate contents of both Hcs were calculated in our previous work to be 1,6 % and 7 % for CaeH and RvH1-a, respectively. We propose that the difference in fluorescence increase of the native CaeH and RvH1-a when titrating them with the complex is due to the fact that the carbohydrate content of CaeH is lower and the carbohydrate chains are buried in between the structural subunits of the native molecule, while the glycans of the functional unit RvH1-a are exposed on the surface of the molecule leading to a 4-fold fluorescence's intensity change.

Abstract
The understanding of the function of macromolecular complexes is mainly related to a precise knowledge of their structure. Recently, the development of suitable mass spectrometric techniques (electrospray ionization (ESI) and matrix-assisted laser desorption/ionization (MALDI)) and multi-angle laser light scattering has enabled mass determination of native complexes and of their subunits. By these techniques, the structure and association/dissociation behavior of huge molecules of molluscan Octopus vulgaris, Sepia officinalis and Rapana venosa have been characterized. Molecular masses of the native and dissociated molecule of cephalopodan Hcs O. vulgaris (3545 and 359.3 kDa, respectively) and S. officinalis (4134 and 443.8 kDa, respectively) revealed that only one type subunit organizes their molecules, while the presence of two isoforms with different masses (422.8 and 400.0 kDa) has been determined for gastropodan R. venosa Hc, aggregated into didecamers. The difference of their structural subunits was also established after limited proteolysis with TPCK-trypsin. Eight functional units (FUs) with masses of ~ 50 kDa were isolated from both subunits of RvH and isoform of Sepia officinalis, while seven FUs were purified from OvH. Further characterization of proteins by ESI-mass spectrometry (MS) and MALDI-MS, methods gave insights into post-translational modifications such as glycosylation. Glycosylation of O. vulgaris and S. officinalis Hcs was suggested based on the differences (11.6 and 40.0 kDa, respectively) between the masses measured by ESI-MS and those calculated by their gene sequences.

Abstract
Allergens from cockroaches cause major asthma-related health problems worldwide. Among them Per a 3 belongs to the most potent allergens. Although the sequences of some members of the Per a 3-family are known, their biochemical and biophysical properties have not been investigated. Here we present for the first time a thorough structural characterization of these allergens, which have recently been tested to induce an increase of allergy specific indicators in blood of Europeans. We isolated two Per a 3 isoforms, which occur freely dissolved in the hemolymph as hexamers with molecular masses of 465+/-25kDa (P II) and 512+/-25kDa (P I). Their sedimentation coefficients (S(20,W)) were determined to be 17.4+/-0.7 S (P II) and 19.0+/-0.9 S (P I), respectively. Sequence analysis revealed that P II consists of two subunit types known as allergens Per a 3.01 and Per a 3.0201, while PI consists of a new allergenic subunit type designated as Per a 3.03. A 3D model of the hexameric allergen Per a 3 was obtained by homology modelling. Almost all of the recently predicted 11 putative antigenic peptides and reported IgE-epitopes could be located on the surface of the hexamer, thus being freely accessible in the hexameric structure of the native molecules. We propose this might contribute to their allergic potential as well as their extreme stability with respect to temperature.

Abstract
Hemocyanins are giant extracellular oxygen carriers in the hemolymph of many molluscs and arthropods with different quaternary structure. They are represented in the hemolymph of molluscs with one, two or three isoforms, as decameric, didecameric, multidecameric and tubules aggregates. We describe here the structure of the hemocyanin Helix lucorum (HlH), species in the series of molluscan hemocyanins. In contrast with other molluscan hemocyanins, three different hemocyanin isopolypeptides were isolated from the hemolymph of the garden snail H. lucorum, named as beta-HlH, alpha(D)-HlH and alpha(N)-HlH. Their molecular masses were determined by size exclusion chromatography to be 1068 kDa (beta-HlH) and 1079 kDa (alpha(D)-HlH, and alpha(N)-HlH). Native HlH exhibits a predominant didecameric structure as revealed by electron microscopy and additionally few tridecamers are shown in the electron micrographs of HlH resulting from the association of a further decamer with one didecamer. The three isoforms are represented mainly as homogeneous didecamers, but they have different behaviour after dissociation and reassociation in the pH-stabilizing buffer, containing 20 mM CaCl(2). All isoforms were reassociated into didecamers and tubules with different length, but in contrast to alpha(D)-HlH isoform, longer tubules were observed in beta-HlH. Moreover the structure of beta-HlH was analysed after limited proteolysis with trypsin followed by FPLC and HPLC separation of the cleavage products. Eight different functional units were identified by their N-terminal sequences and molecular masses. The protein characteristics, including UV absorption at 340 nm, fluorescence and CD spectra of the native molecule and its units confirmed the structure of multimer protein complexes.

Abstract
The blue copper protein hemocyanin from the horseshoe crab Limulus polyphemus is among the largest respiratory proteins found in nature (3.5 MDa) and exhibits a highly cooperative oxygen binding. Its 48 subunits are arranged as eight hexamers (1x6mers) that form the native 8x6mer in a nested hierarchy of 2x6mers and 4x6mers. This quaternary structure is established by eight subunit types (termed I, IIA, II, IIIA, IIIB, IV, V, and VI), of which only type II has been sequenced. Crystal structures of the 1x6mer are available, but for the 8x6mer only a 40 A 3D reconstruction exists. Consequently, the structural parameters of the 8x6mer are not firmly established, and the molecular interfaces between the eight hexamers are still to be defined. This, however, is crucial for understanding how allosteric transitions are mediated between the different levels of hierarchy. Here, we show the 10 A structure (FSC(1/2-bit) criterion) of the oxygenated 8x6mer from cryo-electron microscopy (cryo-EM) and single-particle analysis. Moreover, we show its molecular model as obtained by DNA sequencing of subunits II, IIIA, IV and VI, and molecular modelling and rigid-body fitting of all subunit types. Remarkably, the latter enabled us to improve the resolution of the cryo-EM structure from 11 A to the final 10 A. The 10 A structure allows firm assessment of various structural parameters of the 8x6mer, the 4x6mer and the 2x6mer, and reveals a total of 46 inter-hexamer bridges. These group as 11 types of interface: four at the 2x6mer level (II-II, II-IV, V-VI, IV-VI), three form the 4x6mer (V-V, V-VI, VI-IIIB/IV/V), and four are required to assemble the 8x6mer (IIIA-IIIA, IIIA-IIIB, II-IV, IV-IV). The molecular model shows the amino acid residues involved, and reveals that several of the interfaces are intriguingly histidine-rich and likely to transfer allosteric signals between the different levels of the nested hierarchy.
