Understanding the chemistry of the artificial electron acceptors PES, PMS, DCPIP and Wurster’s Blue in methanol dehydrogenase assays
Bérénice Jahn,Niko S. W. Jonasson,Hurina Hu,Helena Singer,Arjan Pol,Nathan Good,Huub J. M. Op den Camp,N. Cecilia Martinez-Gomez,Lena J. Daumann +8 more
TL;DR: Using mass spectrometry, UV–Vis and electron paramagnetic resonance (EPR) spectroscopy, it is shown that the side reactions of the assay mixture are mainly due to the degradation of assay components.
Americium preferred: LanM, a natural lanthanide-binding protein favors an actinide over lanthanides
TL;DR: In this paper, the authors used the natural lanthanide chelator Lanmodulin and the luminescent probes Eu3+ and Cm3+ to investigate the inter-metal competition behavior of all lanthanides (except Pm) and the major actinide plutonium as well as three minor actinides neptunium, americium and curium to LanModulin.
Neodymium as Metal Cofactor for Biological Methanol Oxidation: Structure and Kinetics of an XoxF1-Type Methanol Dehydrogenase.
Rob A. Schmitz,Nunzia Picone,Helena Singer,Andreas Dietl,Kerstin-Anikó Seifert,Arjan Pol,Mike S. M. Jetten,Thomas R. M. Barends,Lena J. Daumann,Huub J. M. Op den Camp +9 more
TL;DR: In this paper, a neodymium-containing methanol dehydrogenase from a thermoacidophilic methanotroph was shown to have an affinity constant of 1.4 ± 0.6 μM.

Sulfur mustard alkylates steroid hormones and impacts hormone function in vitro
Robin Lüling,Helena Singer,Tanja Popp,Harald John,Ingrid Boekhoff,Horst Thiermann,Lena J. Daumann,Konstantin Karaghiosoff,Thomas Gudermann,Dirk Steinritz +9 more
TL;DR: GCs are presented as new biological targets of SM associated with a disturbance of hormone function as well as biological function of SM-alkylated GCs investigated using GC-regulated dual-luciferase reporter gene assays.
