TL;DR: The thoroughly updated antiSMASH version 4 is presented, which adds several novel features, including prediction of gene cluster boundaries using the ClusterFinder method or the newly integrated CASSIS algorithm, improved substrate specificity prediction for non-ribosomal peptide synthetase adenylation domains based on the new SANDPUMA algorithm, and several usability features have been updated and improved.
Journal ArticleDOI
A new genome-mining tool redefines the lasso peptide biosynthetic landscape
Jonathan I. Tietz,Christopher J. Schwalen,Parth S. Patel,Tucker Maxson,Patricia M. Blair,Hua Chia Tai,Uzma I. Zakai,Douglas A. Mitchell +7 more
TL;DR: RODEO (Rapid ORF Description and Evaluation Online), which combines hidden Markov model-based analysis, heuristic scoring, and machine learning to identify biosynthetic gene clusters and predict RiPP precursor peptides to provide a framework for future genome-mining efforts.
Journal ArticleDOI
YcaO-Dependent Posttranslational Amide Activation: Biosynthesis, Structure, and Function
Brandon J. Burkhart,Christopher J. Schwalen,Greg Mann,James H. Naismith,James H. Naismith,Douglas A. Mitchell +5 more
TL;DR: The formerly enigmatic YcaO superfamily (DUF181), has been found to catalyze a unique phosphorylation of a ribosomal peptide backbone amide upon attack by different nucleophiles.
Journal ArticleDOI
Bioinformatic Expansion and Discovery of Thiopeptide Antibiotics.
TL;DR: A combination of whole-genome sequencing, comparative genomics, and heterologous expression experiments confirmed that the thioamide moiety of saalfelduracin is installed post-translationally by the joint action of two proteins, TfuA and YcaO, reconciling the previously unknown origin of the thaiamide in two long-known thiopeptides.
Journal ArticleDOI
Bioinformatic Mapping of Radical S-Adenosylmethionine-Dependent Ribosomally Synthesized and Post-Translationally Modified Peptides Identifies New Cα, Cβ, and Cγ-Linked Thioether-Containing Peptides

TL;DR: This work bioinformatically mapped the sactipeptide RiPP class via the radical S-adenosylmethionine (SAM) enzymes that form the characteristic sactionine-to-α carbon cross-links between cysteine and acceptor residues and proposed the renaming of the SCIFF family as radical non-α thioether peptides (ranthipeptides) to better distinguish them from the saCTipeptid and lanthipePTide
