Tryptathionine biosynthesis
WebTrypanothione is an unusual form of glutathione containing two molecules of glutathione joined by a spermidine ( polyamine) linker. It is found in parasitic protozoa such as leishmania and trypanosomes. [1] These protozoal parasites are the cause of … WebSynthetic methods on the macrocyclization of peptides are of high interest since they facilitate the synthesis of various types of potentially bioactive compounds, e.g. addressing targets like protein–protein-interactions. Herein, we report on an efficient method to …

WebMay 26, 2010 · Both contain an unusual Trp-Cys cross-bridge known as tryptathionine. We have shown that, in Amanita bisporigera, the amatoxins and phallotoxins are synthesized as proproteins on ribosomes and not by nonribosomal peptide synthetases. The proproteins … WebThis review reports on the various methodologies employed in tryptathionine synthesis, and discusses some of the advantages and disadvantages associated with each of them. The tryptathionine linkage is a crosslink formed between tryptophan and cysteine. This feature is characteristic of the bicyclic peptides: the phallotoxins and the amatoxins. These peptides …
