Abstract
In this study, the effect of free and encapsulated transglutaminase (TGase) on physicochemical, textural, microstructural, microbial, and sensorial properties of white cheese was investigated. For this purpose, different types of white cheese incorporated with 20 and 60 ppm free enzyme (F20 and F60) and encapsulated enzyme (E20 and E60) were prepared and then compared with control (C) white cheese without TGase. The results showed that the addition of encapsulated TGase significantly (p ˂ .05) increased protein and fat content, dry matter, nitrogen recovery, and pH, as well as the production yield of cheeses. The hardness of treated samples was increased during the storage time, while the reverse trend was observed for the control sample. F60 and E60 samples showed more oriented and compact structures compared with other samples. Based on the results of sensory evaluation, E60 sample received the highest taste and flavor scores. Generally, the physicochemical, sensorial, and microstructural properties of white chesses were improved by the presence of encapsulated enzyme in the formulation.

Abstract
Several proteins from animal and plant origin act as microbial transglutaminase substrate, a crosslinking enzyme capable of introducing isopeptide bonds into proteins between the aminoacids glutamines and lysines. This feature has been widely exploited to modify the biological properties of many proteins, such as emulsifying, gelling, viscosity, and foaming. Besides, microbial transglutaminase has been used to prepare bioplastics that, because made of renewable molecules, are able to replace the high polluting plastics of petrochemical origin. In fact, most of the time, it has been shown that the microbial enzyme strengthens the matrix of protein-based bioplastics, thus, influencing the technological characteristics of the derived materials. In this review, an overview of the ability of many proteins to behave as good substrates of the enzyme and their ability to give rise to bioplastics with improved properties is presented. Different applications of this enzyme confirm its important role as an additive to recover high value-added protein containing by-products with a double aim (i) to produce environmentally friendly materials and (ii) to find alternative uses of wastes as renewable, cheap, and non-polluting sources. Both principles are in line with the bio-economy paradigm.

Abstract
The aim of this work was to prepare bioplastics, from renewable and biodegradable molecules, to be used as edible films. In particular, grass pea (Lathyrus sativus L.) flour was used as biopolymer source, the proteins of which were structurally modified by means of microbial transglutaminase, an enzyme able to catalyze isopeptide bonds between glutamines and lysines. We analyzed, by means of Zeta-potential, the flour suspension with the aim to determine which pH is more stable for the production of film-forming solutions. The bioplastics were produced by casting and they were characterized according to several technological properties. Optical analysis demonstrated that films cast in the presence of the microbial enzyme are more transparent compared to the untreated ones. Moreover, the visualization by scanning electron microscopy demonstrated that the enzyme-modified films possessed a more compact and homogeneous structure. Furthermore, the presence of microbial transglutaminase allowed to obtain film more mechanically resistant. Finally, digestion experiments under physiological conditions performed in order to obtain information useful for applying these novel biomaterials as carriers in the industrial field, indicated that the enzyme-treated coatings might allow the delivery of bioactive molecules in the gastro-intestinal tract.

Abstract
In this work, techniques for monitoring the intramolecular transglutaminase cross-links of pea proteins, based on protein size determination, were developed. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis profiles of transglutaminase-treated low concentration (0.01% w/w) pea albumin samples, compared to the untreated one (control), showed a higher electrophoretic migration of the major albumin fraction band (26 kDa), reflecting a decrease in protein size. This protein size decrease was confirmed, after DEAE column purification, by dynamic light scattering (DLS) where the hydrodynamic radius of treated samples appears to be reduced compared to the control one.

Abstract
Avidin conjugates have several important applications in biotechnology and medicine. In this work, we investigated the possibility to produce site-specific derivatives of avidin using microbial transglutaminase (TGase). TGase allows the modification of proteins at the level of Gln or Lys residues using as substrate an alkyl-amine or a Gln-mimicking moiety, respectively. The reaction is site-specific, since Gln and Lys derivatization occurs preferentially at residues embedded in flexible regions of protein substrates. An analysis of the X-ray structure of avidin allowed us to predict Gln126 and Lys127 as potential sites of TGase's attack, because these residues are located in the flexible/unfolded C-terminal region of the protein. Surprisingly, incubation of avidin with TGase in the presence of alkylamine containing substrates (dansylcadaverine, 5-hydroxytryptamine) revealed a very low level of derivatization of the Gln126 residue. Analysis of the TGase reaction on synthetic peptide analogues of the C-terminal portion of avidin indicated that the lack of reactivity of Gln126 was likely due to the fact that this residue is proximal to negatively charged carboxylate groups, thus hampering the interaction of the substrate at the negatively charged active site of TGase. On the other hand, incubation of avidin with TGase in the presence of carbobenzoxy-l-glutaminyl-glycine in order to derivatize Lys residue(s) resulted in a clean and high yield production of an avidin derivative, retaining the biotin binding properties and the quaternary structure of the native protein. Proteolytic digestion of the modified protein, followed by mass spectrometry, allowed us to identify Lys127 as the major site of reaction, together with a minor modification of Lys58. By using TGase, avidin was also conjugated via a Lys-Gln isopeptide bond to a protein containing a single reactive Gln residue, namely, Gln126 of granulocyte-macrophage colony-stimulating factor. TGase can thus be exploited for the site-specific derivatization of avidin with small molecules or proteins.

Abstract
Apomyoglobin is an excellent example of a monomeric all α-helical globular protein whose folding pathway has been extensively studied and well characterized. Structural perturbation induced by denaturants or high temperature as well as amino acid substitution have been described to induce misfolding and, in some cases, aggregation. In this article, we review the molecular mechanism of the aggregation process through which a misfolded form of a mutated apomyoglobin aggregates at physiological pH and room temperature forming an amyloid fibril. The results are compared with data showing that either amyloid or aggregate formation occurs under particular denaturing conditions or upon cleavage of the residues corresponding to the C-terminal helix of apomyoglobin. The results are discussed in terms of the sequence regions that are more important than others in determining the amyloid aggregation process.

Abstract
A range of debilitating human diseases is known to be associated with the formation of stable highly organized protein aggregates known as amyloid fibrils. The early prefibrillar aggregates behave as cytotoxic agents and their toxicity appears to result from an intrinsic ability to impair fundamental cellular processes by interacting with cellular membranes, causing oxidative stress and increase in free Ca(2+) that lead to apoptotic or necrotic cell death. However, specific signaling pathways that underlie amyloid pathogenicity remain still unclear. This work aimed to clarify cell impairment induced by amyloid aggregated. To this end, we used a combined proteomic and one-dimensional (1) H-NMR approach on NIH-3T3 cells exposed to prefibrillar aggregates from the amyloidogenic apomyoglobin mutant W7FW14F. The results indicated that cell exposure to prefibrillar aggregates induces changes of the expression level of proteins and metabolites involved in stress response. The majority of the proteins and metabolites detected are reported to be related to oxidative stress, perturbation of calcium homeostasis, apoptotic and survival pathways, and membrane damage. In conclusion, the combined proteomic and (1) H-NMR metabonomic approach, described in this study, contributes to unveil novel proteins and metabolites that could take part to the general framework of the toxicity induced by amyloid aggregates. These findings offer new insights in therapeutic and diagnostic opportunities.
