Food-protein derived bioactive peptides are short amino acid chains that are inactive within the sequence of the parent protein, but can be released through hydrolysis by proteolytic enzymes. Several physiological effects have been attributed to these peptides, such as blood pressure reduction, scavenging of oxidative compounds, induction of satiety and reduction of cholesterol. Due to their ab...

Biointerface design that targets osteogenesis is a growing area of research with significant implications in biomedicine. Materials known to either support or stimulate osteogenesis are composed of a biomimetic ceramic material, such as bioactive glass. Bioactive glass is osteoproductive, and the potential for osteoproductivity can be enhanced by the addition of proteins or other additives desi...

Bioactive peptide database (BioPD) is a web-based knowledge base that contains more than 1100 protein sequences from human, mouse and rat, which are putative or are known to be bioactive peptides. In addition to peptide sequences and the annotation, the database also contains gene sequences with annotation, protein interaction and disease data related to the peptides. Each entry has as many ref...

Anginex is a designed peptide 33mer that functions as a cytokine-like agent to inhibit angiogenesis. Although this short linear peptide has been shown by NMR and CD to form a nascent beta-sheet conformation in solution, the actual bioactive structure formed upon binding to its receptor on the surface of endothelial cells could be quite different. By using a series of double-cysteine disulphide-...

Traumatic brain injury (TBI) is a common reason of brain tissue loss as a result of tumors, accidents, and surgeries. Renewal of the brain parenchyma is restricted by many reasons such as inimical substances produced as the result of trauma and also inflammatory responses. A strong cascade of inflammatory responses begins as a result of TBI which include recalling peripheral leukocytes into the...

Present study highlights on isolation of bioactive peptide from the sesame protein hydrolysate with an objective of better utilization sesame meal. Sesame protein isolate was enzymatically modified to prepare sesame protein hydrolysate using enzyme ‘Protease A Amano 2G’ in an enzyme membrane reactor and the hydrolysate was subsequently fractionated by ultrafiltration using membranes of decreasi...

Antioxidative and antihypertensive bioactive peptides were successfully derived from Parkia speciosa seed using alcalase. The effects of temperature (25 and 50 °C), substrate-to-enzyme ratio (S/E ratio, 20 and 50), and incubation time (0.5, 1, 2 and 5h) were evaluated based on 2,2-diphenyl-1-picrylhydrazyl (DPPH), ferric reducing antioxidant power (FRAP) and angiotensin-converting enzyme (ACE) ...

It has been well recognized that the modification of biomaterials with appropriate bioactive peptides could further enhance their functions. Especially, it has been shown that peptide-modified bone repair materials could promote new bone formation more efficiently compared with conventional ones. The purpose of this article is to give a general review of recent studies on bioactive peptide-modi...

Peptide-amphiphiles are amphiphilic structures with a hydrophilic peptide headgroup that incorporates a bioactive sequence and has the potential to form distinct structures, and a hydrophobic tail that serves to align the headgroup, drive self-assembly, and induce secondary and tertiary conformations. In this paper we review the different self-assembled structures of peptide-amphiphiles that ra...

Understanding the dynamic behavior of nanostructural systems is important during the development of controllable and tailor-made nanomaterials. This is particularly true for nanostructures that are intended for biological applications because biomolecules are usually highly dynamic and responsive to external stimuli. In this Article, we investigated the structural and conformational dynamics of...
