Noncanonical Peloruside A Biosynthesis by an Uncultivated Verrucomicrobiota Symbiont

open access: yesAngewandte Chemie, EarlyView.
Noncanonical biochemistry of the peloruside PKS characterized in this work, comprising double bond generation by a noncanonical tridomain (blue), acetyl‐CoA recycling (orange), and proofreading systems (purple and yellow). The Z‐double bond is installed by TEB1 through O‐acetylation and acetate elimination. The acyl ligase PelB (AL, orange) selectively

Updatable Closed‐Form Evaluation of Arbitrarily Complex Multiport Network Connections

open access: yesAdvanced Electronic Materials, EarlyView.
The inverse design of electrically large wave devices often uses reduced‐order multiport models with discrete optimization, requiring many evaluations of complex interconnections between subsystems that differ only in a few blocks. This paper introduces a closed‐form framework enabling efficient Woodbury low‐rank updates of related, previous ...

Structural and Functional Siderophore Remodeling by Enzymatic Delipidation

open access: yesAngewandte Chemie, EarlyView.
A surprising functional switch in bacterial siderophores was discovered through genome mining and the analysis of environmental and pathogenic Pandoraea species. Pandorachelin B, a lipocyclopeptide that promotes swarming motility, is cleaved by a specialized acylase, yielding a ring‐contracted, homodetic cyclopeptide, pandorachelin A, which exhibits ...
