Friedelin synthase
WebFriedelin (friedelan-3-one) is the only one compound having a friedelane skeleton reported from genus Myrianthus, notably from trunk wood of Myrianthus serratus (Fig. 1.3) [31]. Friedelin is a triterpenoid ketone formed biosynthetically after the numerous rearrangements of the dammarenyl cation [1,2]. Additionally, the primary fundamental ... WebA 2-oxoglutarate-dependent dioxygenase (EC 1.14.11.11) which catalyzes the 4-hydroxylation of desacetoxyvindoline was purified to homogeneity. Three oligopeptides isolated from a tryptic digest of the purified protein were microsequenced and one oligopeptide showed significant homology to hyoscyamine 6β-hydroxylase from …

WebMar 30, 2024 · The friedelin synthase utilized in the present work was characterized from mRNA from the leaves of Maytenus ilicifolia and therefore named MiFRS (Souza-Moreira et al. 2016). Its substrate 2,3-oxidosqualene is produced in yeast and cyclized to lanosterol as part of the ergosterol pathway (Corey, Matsuda and Bartel 1994). Webof friedelin synthase, TwOSC1, with threonine 502 changed to glutamic acid, was able to increase the heterologous production of friedelin instead of changing its specificity, showing the potential impact of mutagenesis studies in understanding and improving friedelin production. Therefore, the goal of this paper was to evaluate the role of ...
WebNov 11, 2024 · Friedelin synthase produces friedelin, which involves the highest number of rearrangements in the triterpene biosynthetic pathways . It is hypothesized that an aspartate residue starts the carbocation reaction. Then, it promotes the hydroxylation of an intermediate, which is deprotonated by the same residue yielding a ketone.
