“…Extracts from different higher plants, especially from cereals, were proven to have class I chitinase isoforms and those from oat seed extracts were demonstrated to be more effective toward Penicillium roqueforti, a major contaminating fungal species in food, as opposed to extracts of others cereal seeds [13]. Oats (Avena sativa L.) are members of the Poaceae family and are recognized as useful plants for a healthier world thanks to their beneficial and nutritional components uses [14]. Avena sativa has a complex genome, which is not completely sequenced.…”

The abundance and the diversity of oligo-and polysaccharides provide a wide range of biological roles attributed either to these carbohydrates or to their relevant enzymes, i.e., the glycoside hydrolases (GHs). The biocatalysis by these families of enzymes is highly attractive for the generation of products used in potential applications, e.g., pharmaceuticals and food industries. It is thus very important to extract and characterize such enzymes, particularly from plant tissues. In this study, we characterized novel sequences of class I chitinases from seedlings extract of the common oat (Avena sativa L.) using proteomics and sequence-structure-function analysis. These enzymes, which belong to the GH19 family of protein, were extracted from oat and identified using SDS-PAGE, trypsin digestion, LC-MS-MS, and sequence-structure-function analysis. The amino acid sequences of the oat tryptic peptides were used to identify cDNAs from the Avena sativa databases of the expressed sequence tags (ESTs) and transcriptome shotgun assembly (TSA). Based upon the Avena sativa sequences of ESTs and TSA, at least 4 predicted genes that encoded oat class I chitinases were identified and reported. The structural characterization of the oat sequences of chitinases provided valuable insights to the context.

Oat (Avena sativa) is a cereal known since antiquity as a useful grain with abundant nutritional and health benefits. It contains distinct molecular components with high antioxidant activity, such as tocopherols, tocotrienols, and flavanoids. In addition, it is a unique source of avenanthramides, phenolic amides containing anthranilic acid and hydroxycinnamic acid moieties, and endowed with major beneficial health properties because of their antioxidant, anti-inflammatory, and antiproliferative effects. In this review, we report on the biological activities of avenanthramides and their derivatives, including analogs produced in recombinant yeast, with a major focus on the therapeutic potential of these secondary metabolites in the treatment of aging-related human diseases. Moreover, we also present recent advances pointing to avenanthramides as interesting therapeutic candidates for the treatment of cerebral cavernous malformation (CCM) disease, a major cerebrovascular disorder affecting up to 0.5% of the human population. Finally, we highlight the potential of foodomics and redox proteomics approaches in outlining distinctive molecular pathways and redox protein modifications associated with avenanthramide bioactivities in promoting human health and contrasting the onset and progression of various pathologies. The paper is dedicated to the memory of Adelia Frison

“…All these nutrients and compounds possess potential properties and health benefits [6]. This cereal contain also high amounts of lipids compared with other cereal seeds, with high content of unsaturated fatty acids [10]. These components determines in large measure its technological properties and functionalities in processing [28,29].…”

Physico-chemical, functional and antioxidant capacities of 26 oat (Avena sativa L.) lines and cultivars were investigated. The results showed that the contents were considerably variable within samples, starch concentration (44,83-63,79%), carbohydrate (42,08-62,65%), protein (9,67-17,44%), fat (3,06-10,96%), β-glucan (1,37-6,05%) and ash (1,22-5,38%). The analysis of fatty acids composition indicated that, palmitic acid, oleic acid, linoleic acid, stearic acid and linolenic were the major fatty acids in oat lipids, and that the contents of total UFA in assessed material varied between72, 29-80,11%. Moreover, the phenolic content varied from 23,1 to 56,5 mg GAE/100g, carotenoids content range from 0,98 to 4,34 µg β-carotene equivalents/g and antioxidant activity, evaluated as DPPH radical scavenging activity, from 12,2 to 46,7%. The Protein profiles showed nearly identical nature of electrophoresis patterns, indicating no eventual change in protein quality. It could be concluded here that the flour of issue from these cultivars provide health benefits and high added value, if included as an ingredient for making new functional food products to meet the demands of health conscious generation.
