Citrinin pathway
Citrinin is a mycotoxin which is often found in food. It is a secondary metabolite produced by fungi that contaminates long-stored food and it causes different toxic effects, like nephrotoxic, hepatotoxic and cytotoxic effects. Citrinin is mainly found in stored grains, but sometimes also in fruits and other plant products. See more Citrinin was one of the many mycotoxins discovered by H. Raistrick and A.C. Hetherington in the 1930s. In 1941 H. Raistrick and G. Smith identified citrinin to have a broad antibacterial activity. After this discovery the … See more Citrinin is a polyketide mycotoxin, which is a secondary metabolite of some fungi species. Its IUPAC name is (3R,4S)-4,6-dihydro-8-hydroxy-3,4,5-trimethyl-6-oxo-3H-2-benzopyran-7-carboxylic acid and the molecular formula is C13H14O5. Citrinin has a … See more Citrinin is biosynthesized by fungi species of Penicillium, Monascus and Aspergillus. For the production of citrinin, a minimal set of genes is needed. These genes are conserved in most … See more Reddy et al. (1982) described the distribution and metabolism of [ C]Citrinin in pregnant rats. These rats were subcutaneously administered with 35 mg/kg C-labeled citrinin on day 12 of pregnancy. From plasma concentrations it could be concluded … See more The existing information on occurrence of citrinin in food suggests that relatively high citrinin concentrations can be found in stored grains and … See more There are different types of toxicity. The types of toxicity that have been studied for citrinin are acute toxicity, nephrotoxicity, genotoxicity and its carcinogenicity. Acute toxicity See more Various in vitro studies have revealed the involvement of citrinin toxicity in reduced cytokine production, inhibition of RNA and DNA synthesis, … See more WebTo learn more about the citrinin biosynthetic pathway, a ctnG-replacement vector was constructed to disrupt ctnG with the hygromycin resistance gene as the selection marker, then transformed into M. aurantiacus Li AS3.4384 by a protoplast-PEG method. The citrinin content of three disruptants was reduced to about 50%, meanwhile pigment ...
