Reducing Properties

А new way of the free radical ROS- and HOCl-induced destruction of serine, threonine, and their peptide derivatives due to the nitrogen-centered radicals formation and their subsequent decomposition with the side chain elimination has been established. It has been shown that substances with reducing properties are inhibitors of this process, while oxygen does not affect the probability of its occurrence. The data obtained are relevant for the development of novel approaches to the search for effective free radical processes regulators.

AbstractMany important natural products are produced by non-ribosomal peptide synthetases (NRPSs) 1.These giant enzyme machines activate amino acids in an assembly line fashion in which a set of catalytically active domains is responsible for the section, activation, covalent binding and connection of a specific amino acid to the growing peptide chain 1,2. Since NRPS are not restricted to the incorporation of the 20 proteinogenic amino acids, their efficient manipulation would give access to a diverse range of peptides available biotechnologically. Here we describe a new fusion point inside condensation (C) domains of NRPSs that enables the efficient production of peptides, even containing non-natural amino acids, in yields higher than 280 mg/L. The technology called eXchange Unit 2.0 (XU2.0) also allows the generation of targeted peptide libraries and therefore might be suitable for the future identification of bioactive peptide derivatives for pharmaceutical and other applications.
