“…Later, two additional fungal 4-DMATS, i.e., DmaW-Cs from Periglandula (Markert et al 2008;Steiner et al 2011) and Malbranchea (Ding et al 2008), were also identified. Identification of 7-DMATS from A. fumigatus as a tryptophan C7-prenylating enzyme obligated to donate the position of the prenyl moiety at the indole ring of tryptophan for prenyltransferase names.…”

Attachment of isoprene units to various acceptors by prenylation plays an important role in primary and secondary metabolism of living organisms. Protein prenylation belongs to posttranslational modification and is involved in cellular regulation process. Prenylated secondary metabolites usually demonstrate promising biological and pharmacological activities. Prenyl transfer reactions catalyzed by prenyltransferases represent the key steps in the biosynthesis and contribute significantly to the structural and biological diversity of these compounds. In the last decade, remarkable progress has been achieved in the biochemical, molecular, and structural biological investigations of prenyltransferases, especially on those of the members of the dimethylallyltryptophan synthase (DMATS) superfamily. Until now, more than 40 of such soluble enzymes are identified and characterized biochemically. They catalyze usually regioselective and stereoselective prenylations of a series of aromatic substances including tryptophan, tryptophan-containing peptides, and other indole derivatives as well as tyrosine or even nitrogen-free substrates. Crystal structures of a number of prenyltransferases have been solved in the past 10 years and provide a solid basis for understanding the mechanism of prenyl transfer reactions.

“…In addition to 5-DMATS described in this study, several DMATSs using L-tryptophan as natural or best aromatic substrate with different regioselectivity have been studied biochemically in detail, e.g. the 4-DMATS FgaPT2 from A. fumigatus (20) and its orthologues MaPT from Malbranchea aurantiaca (50) and DmaW from a clavicipitalean fungus (51,52), the 6-DMATS IptA from Streptomyces sp. SN-593 (13), and the 7-DMATS from A. fumigatus (22).…”

Background: Known indole prenyltransferases catalyzed regioselective prenylations at N-1, C-2, C-3, C-4, C-6, and C-7 of the indole ring. Results: Recombinant 5-DMATS was assayed with tryptophan and derivatives in the presence of DMAPP. Conclusion: 5-DMATS prenylated indole derivatives at C-5. Significance: 5-DMATS fills the last prenylation gap of indole derivatives and could be used as a potential catalyst for chemoenzymatic synthesis.

Towards a natural classification and backbone tree for Sordariomycetes

et al. 2015

Sordariomycetes is one of the largest classes of Ascomycota and is characterised by perithecial ascomata and inoperculate unitunicate asci. The class includes many important plant pathogens, as well as endophytes, saprobes, epiphytes, and fungicolous, lichenized or lichenicolous taxa. The class includes freshwater, marine and terrestrial taxa and has a worldwide distribution. This paper provides an updated outline of the Sordariomycetes and a backbone tree incorporating asexual and sexual genera in the class. Based on phylogeny and morphology we introduced three subclasses; D i a p o r t h o m y c e t i d a e , L u l w o r t h i o m y c e t i d a e a n dTogniniales. The outline is based on literature to the end of 2014 and the backbone tree published in this paper. Notes for 397 taxa with information, such as new family and genera novelties, novel molecular data published since the Outline of Ascomycota 2009, and new links between sexual and asexual genera and thus synonymies, are provided. The Sordariomycetes now comprises six subclasses, 28 orders, 90 families and 1344 genera. In addition a list of 829 genera with uncertain placement in Sordariomycetes is also provided.
