Abstract
Nanoparticles based on chitosan modified with epigallocatechin gallate (EGCG) were synthetized by nanoprecipitation (EGCG-g-chitosan-P). Chitosan was modified by free-radical-induced grafting, which was verified by Fourier transform infrared (FTIR). Furthermore, the morphology, particle size, polydispersity index, and zeta potential of the nanoparticles were investigated. The grafting degree of EGCG, reactive oxygen species (ROS) production, antibacterial and antioxidant activities of EGCG-g-chitosan-P were evaluated and compared with those of pure EGCG and chitosan nanoparticles (Chitosan-P). FTIR results confirmed the modification of the chitosan with EGCG. The EGCG-g-chitosan-P showed spherical shapes and smoother surfaces than those of Chitosan-P. EGCG content of the grafted chitosan nanoparticles was 330 μg/g. Minimal inhibitory concentration (MIC) of EGCG-g-chitosan-P (15.6 μg/mL) was lower than Chitosan-P (31.2 μg/mL) and EGCG (500 μg/mL) against Pseudomonas fluorescens (p < 0.05). Additionally, EGCG-g-chitosan-P and Chitosan-P presented higher Staphylococcus aureus growth inhibition (100%) than EGCG at the lowest concentration tested. The nanoparticles produced an increase of ROS (p < 0.05) in both bacterial species assayed. Furthermore, EGCG-g-chitosan-P exhibited higher antioxidant activity than that of Chitosan-P (p < 0.05) in 2,2'-azino-bis (3-ethyl-benzothiazoline-6-sulfonic acid) (ABTS), 2,2-diphenyl-1-picrylhydrazyl radical (DPPH) and ferric-reducing antioxidant power assays. Based on the above results, EGCG-g-chitosan-P shows the potential for food packaging and biomedical applications.

Abstract
BACKGROUND Trypsin from fish species is considered as a cold-adapted enzyme that may find potential biotechnological applications. In this work, the recombinant expression, refolding and activation of Trypsin I (TryI) from Monterey sardine (Sardinops sagax caerulea) are reported. METHODS TryI was overexpressed in Escherichia coli BL21 as a fusion protein of trypsinogen with thioredoxin. Refolding of trypsinogen I was achieved by dialysis of bacterial inclusion bodies with a recovery of 16.32 mg per liter of Luria broth medium. RESULTS Before activation, the trypsinogen fusion protein did not show trypsin activity. Trypsinogen I was activated by adding 0.002 U of native TryI purified from the sardine pyloric caeca (nonrecombinant). The activated recombinant trypsin showed three times more activity than the nonrecombinant trypsin alone. CONCLUSION The described protocol allowed obtaining sufficient amounts of recombinant TryI from Monterey sardine fish for further biochemical and biophysical characterization of its coldadaptation parameters.

Abstract
Nucleoside diphosphate kinase (NDK; EC 2.7.4.6) is an enzyme that catalyzes the third phosphorylation of nucleoside diphosphates, leading to nucleoside triphosphates for DNA replication. Expression of the NDK from Litopenaeus vannamei (LvNDK) is known to be regulated under viral infection. Also, as determined by isothermal titration calorimetry, LvNDK binds both purine and pyrimidine deoxynucleoside diphosphates with high binding affinity for dGDP and dADP and with no heat of binding interaction for dCDP [Quintero-Reyes et al. (2012), J. Bioenerg. Biomembr. 44, 325-331]. In order to investigate the differences in selectivity, LvNDK was crystallized as binary complexes with both acceptor (dADP and dCDP) and donor (ADP) phosphate-group nucleoside diphosphate substrates and their structures were determined. The three structures with purine or pyrimidine nucleotide ligands are all hexameric. Also, the binding of deoxy or ribonucleotides is similar, as in the former a water molecule replaces the hydrogen bond made by Lys11 to the 2'-hydroxyl group of the ribose moiety. This allows Lys11 to maintain a catalytically favourable conformation independently of the kind of sugar found in the nucleotide. Because of this, shrimp NDK may phosphorylate nucleotide analogues to inhibit the viral infections that attack this organism.

Abstract
Biosynthesis of nucleoside triphosphates is critical for bioenergetics and nucleic acid replication, and this is achieved by nucleoside diphosphate kinase (NDK). As an emerging biological model and the global importance of shrimp culture, we have addressed the study of the Pacific whiteleg shrimp (Litopenaeus vannamei) NDK. We demonstrated its activity and affinity towards deoxynucleoside diphosphates. Also, the quaternary structure obtained by gel filtration chromatography showed that shrimp NDK is a trimer. Affinity was in the micro-molar range for dADP, dGDP, dTDP and except for dCDP, which presented no detectable interaction by isothermal titration calorimetry, as described previously for Plasmodium falciparum NDK. This information is particularly important, as this enzyme could be used to test nucleotide analogs that can block white spot syndrome virus (WSSV) viral replication and to study its bioenergetics role during hypoxia and fasting.
