WebJun 4, 2024 · Citrinin dominates the fermentation extracts of WT, but no citrinin can be detected in Δcits, suggesting that CitS is essential for citrinin biosynthesis. Besides, intriguingly, as shown in Figure 4 , several peaks with retention time from 26 to 28 min were emerged and enhanced in Δcits when compared with WT. WebIn comparison to the parental strain, the ΔctnB mutants barely produced citrinin. These data confirmed that the ctnB gene is directly involved in citrinin biosynthesis. Moreover, the yields of the pigments of two disruptants were similar to that of the wild-type strain, but the yield of another mutant was slightly higher than that of the ...
WebLadderane lipids (found in the membranes of anaerobic ammonium-oxidizing [anammox] bacteria) have unique ladder-like hydrophobic groups, and their highly strained exotic structure has attracted the attention of scientists. Although enzymes encoded in type II fatty acid biosynthesis (FASII) gene clusters in anammox bacteria, such as S-adenosyl-l … 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 species which produce citrinin. They are citS, mrl1, mrl2, mrl4, mrl6, and mrl7. CitS produces a citrinin synthase (CitS). The product of the mrl1 gene is a serine hydrolase (CitA), but its function is not known yet. Mrl2 encodes a non heme Fe(II) dependent oxygenase (CitB) which is involved i…
