Crystal Structure of an (R)-Selective ω-Transaminase from Aspergillus terreus

open access: yesPLoS ONE, 2014
Chiral amines are important building blocks for the synthesis of pharmaceutical products, fine chemicals, and agrochemicals. ω-Transaminases are able to directly synthesize enantiopure chiral amines by catalysing the transfer of an amino group from a ...

Engineering Bacterial Secretion Systems for Enhanced Tumor Imaging and Surgical Guidance

open access: yesAdvanced Materials, EarlyView.
This study presents a novel contrast agent platform, Streptavidin Associated Salmonella (SAS), for fluorescence image guided surgery. SAS selectively colonizes tumors and secretes streptavidin, enabling precise delineation of invasive tumor margins with prolonged signal retention.

Analysis of serum glutamic pyruvic transaminase and serum glutamic oxaloacetic transaminase levels in tuberculosis patients who are undergoing oat treatment in Kendari City General Hospital, Kota Kendari, Indonesia

open access: yesInfectious Disease Reports, 2020
In the treatment of tuberculosis (TB), the patient is generally directly given Anti Tuberculosis Drugs (Obat Anti Tuberculosis/OAT) without examining Serum Glutamic Pyruvic Transaminase (SGPT) and Serum Glutamic Oxaloacetic Transaminase (SGOT) to see ...

Reengineering Endogenous Targeting Lipid Nanoparticles (ENDO) for Systemic Delivery of mRNA to Pancreas

open access: yesAdvanced Materials, EarlyView.
ENDO lipid nanoparticles containing cholecalciferol as a fifth component demonstrate mRNA delivery to the pancreas with 99% selectivity, including beta cells. This platform shows minimal toxicity and sustained protein expression for up to 3 days in a dose‐dependent manner, offering a novel approach to pancreas‐specific mRNA delivery and gene therapy ...

Development of Photo‐Biocatalytic Redox System for Asymmetric Synthesis of Optically Active Amines Using Blue Light and Transaminases. A Case Study Toward Mavacamten

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
Abstract α‐Chiral amines are versatile building blocks for the asymmetric synthesis of optically pure high‐added‐value chemicals, including pharmaceuticals, agrochemicals, and natural products. Herein, we report a one‐pot, two‐step sequential deracemization of racemic sec‐alcohols to optically enriched primary amines throught a photo‐biocatalytic ...

Anion-π transaminase mimics

open access: yesSupramolecular Chemistry, 2016
The possibility to stabilise anionic transition states on π-acidic aromatic surfaces has been explicitly demonstrated first in 2013. Since then, anion-π catalysis has been introduced to asymmetric enamine and iminium chemistry and to cascade processes, and the first anion-π enzyme has been created.

Ammonia Dynamics in the Human Body: Insights in Biomedical Sensing Technologies

open access: yesAdvanced Sensor Research, EarlyView.
Ammonia (NH3) is a significant biomarker in diagnostics, affecting the respiratory system, stomach, liver, kidneys, bladder, and gastrointestinal tract. NH3 detection, using sensors, has the potential to improve medical diagnosis. This review examines recent advancements in NH3 sensing technologies and explores future research directions, including ...
