The number of both naturally occurring and synthesized biologically active cyclic peptides, modified peptides, and peptide mimics is rapidly increasing. So far, many of these sometimes biologically very potent peptides have unfortunately unknown molecular targets or mechanisms of action. This certainly opens up very interesting and challenging research areas with respect to uncovering these tar...
The recent increase in extensively drug-resistant bacterial pathogens and the associated increase of morbidity and mortality demonstrate the immediate need for new antibiotic backbones with novel mechanisms of action. Here, we report the development of the PepSAVI-MS pipeline for bioactive peptide discovery. This highly versatile platform employs mass spectrometry and statistics to identify bio...
Bioactive molecules (or signaling molecules) are involved in tissue regeneration and have an important role modulating the microenvironment vivo. chemicals ability to govern host cell motility, proliferation, differentiation, as well enabling cells interact with their surrounding via particular receptors for chemical recognition. This chapter introduces ion-exchange chromatography (IEC) a metho...
BACKGROUND The Resonant Recognition Model (RRM) is a physico-mathematical model that interprets protein sequence linear information using digital signal processing methods. In this study the RRM concept was employed for structure-function analysis of myxoma virus (MV) proteins and the design of a short bioactive therapeutic peptide with MV-like antitumor/cytotoxic activity. METHODOLOGY/PRINCI...
Solid-phase peptide synthesis in the N-to-C direction, opposite to the classical C-to-N direction of peptide synthesis, provides the synthetically versatile C-terminal carboxyl group for further modification into C-terminally modified peptide mimetics. These are of general interest as potential bioactive agents, particularly as protease inhibitors. Elaboration of peptide mimetics on the solid-p...
Peptide amphiphiles are a class of molecules that combine the structural features of amphiphilic surfactants with the functions of bioactive peptides and are known to assemble into a variety of nanostructures. A specific type of peptide amphiphiles are known to self-assemble into one-dimensional nanostructures under physiological conditions, predominantly nanofibers with a cylindrical geometry....
Most growth factors are initially synthesized as precursors and it was cleaved into bioactive mature domain and pro-domain. However, compared with the expression and function of bioactive mature domain, the biological role of the pro-domain is poorly understood. Unexpectedly, we found that the pro-domain (or pro-peptide) of brain-derived neurotrophic factor (BDNF), which is well-known neurotrop...
Recent research has shown that fish residual materials contain a range of components with interesting biological activity. Therefore, there is a great potential in the marine bioprocess industry to utilize these by-products as starting material for generating more valuable products. The aim of the present study was to search for bioactive peptides (in particular small natural bioactive peptides...
Modular polyketide synthases and nonribosomal peptide synthetases are giant multienzymes that catalyze the assembly of a wide variety of bioactive natural products including several important clinical drugs. In simple mechanical terms, these systems function as molecular assembly lines, where each domain in the multienzyme performs its task once during the assembly process. However, several pol...
