Cooperative Photometallobiocatalysis: Nonheme Fe Enzyme‐Catalyzed Enantioconvergent Radical Decarboxylative Azidation, Thiocyanation, and Isocyanation of Redox‐Active Esters

Angewandte Chemie, EarlyView.
Through the directed evolution of an underexploited nonheme Fe extradiol dioxygenase, we developed a unified cooperative photobiocatalytic strategy to allow for three types of enantioconvergent radical transformations, including azidation, thiocyanation, and isocyanation.

Phylogenetic Resolution and Quantifying the Phylogenetic Diversity and Dispersion of Communities

PLoS ONE, 2009
Conservation biologists and community ecologists have increasingly begun to quantify the phylogenetic diversity and phylogenetic dispersion in species assemblages. In some instances, the phylogenetic trees used for such analyses are fully bifurcating, but in many cases the phylogenies being used contain unresolved nodes (i.e. polytomies).

Invariants for level-1 phylogenetic networks under the random walk 4-state Markov model [PDF]

arXiv
Phylogenetic networks can represent evolutionary events that cannot be described by phylogenetic trees, such as hybridization, introgression, and lateral gene transfer. Studying phylogenetic networks under a statistical model of DNA sequence evolution can aid the inference of phylogenetic networks.

Bounding the softwired parsimony score of a phylogenetic network [PDF]

arXiv
In comparison to phylogenetic trees, phylogenetic networks are more suitable to represent complex evolutionary histories of species whose past includes reticulation such as hybridisation or lateral gene transfer. However, the reconstruction of phylogenetic networks remains challenging and computationally expensive due to their intricate structural ...

Identification of an Activity Selector for the Nitroso‐Forming Activity in Bacterial Type‐III Copper Enzymes

Angewandte Chemie International Edition, EarlyView.
Small but crucial difference: Type‐III copper enzymes, like tyrosinase (TYR) and o‐aminophenol oxidase (AO), catalyze the oxidation of o‐aminophenols (AP) to quinone imines. Unlike TYR, AO can further oxidize AP to nitrosophenols. This nitroso‐forming activity is controlled by a key amino acid near the Cu(A) ion.

Mixing and Matching of Hybrid Megasynthases is a Hub for the Evolution of Metabolic Diversity in Cyanobacteria

Angewandte Chemie International Edition, EarlyView.
Natural combinatorics: Evolutionary mixing and matching of three cyanobacterial biosynthetic gene clusters resulted in the emergence of minutumamides, a novel family of peptide‐polyketide hybrids. Retro‐evolutionary analysis led to the discovery of nostopeptolide KVJ3, an evolutionary ancestor that links nostopeptolide and minutumamide biosynthesis and
