Nonheme Fe Enzyme‐Catalyzed Enantiodivergent Nitrogen Migration: Directed Evolution and Computational Study of Isopenicillin N Synthases for Biocatalytic Synthesis of Arylglycines

open access: yesAngewandte Chemie, EarlyView.
Nonheme Fe enzyme isopenicillin N synthase was reprogrammed and evolved as an efficient nitrogen migratase IPNSNim, converting diverse azanyl esters to valuable l‐arylglycines with up to 16 000 TTN and 97:3 e.r. IPNSNim and ACCONim allowed enantiodivergent preparation of both l‐ and d‐arylglycines.

Total Synthesis of (+)‐Melonine and (+)‐N4‐Oxy Melonine Enabled by an Intramolecular Alkene Diamination Reaction

open access: yesAngewandte Chemie, EarlyView.
A complexity‐generating intramolecular alkene diamination constitutes the pivotal step in the enantioselective synthesis of the title natural products featuring a strained, cage‐like pentacyclic architecture. Abstract Among more than four thousand monoterpene indole alkaloids (MIAs) isolated to date, only a few feature a 2,2,3‐trisubstituted indoline ...

Structural problems without structural solutions? Youth leaders' perceptions of their community

open access: yesAmerican Journal of Community Psychology, EarlyView.
Abstract As young people explore and reflect on the conditions of their neighborhoods and communities, they can forge a critical consciousness—merging their perspectives and analysis to direct both individual and collective actions. Photovoice is a methodological tool that allows participants to document their perspectives and analysis and discuss with

Marfan Syndrome Associated With Intellectual Disability and Behavioral Anomalies: Further Evidence for the Effect of Compound Heterozygous Variants in FBN1 on Phenotypic Severity

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Marfan syndrome (MFS) is a rare connective tissue disorder characterized by involvement of the cardiovascular, ocular, and musculoskeletal systems. Pathogenic variants in FBN1 cause most of the MFS cases; however, intellectual disability (ID) is rarely observed. A non‐consanguineous Pakistani family with four affected individuals was recruited.
