Structural Basis for a Scaffolding Role of the COM Domain in Nonribosomal Peptide Synthetases
Angewandte Chemie, EarlyView.COM domains are known as docking domains between subunits of nonribosomal peptide synthetases (NRPSs). Here, the first structure of a fused, internal COM domain with its neighboring domains is reported. Structural, biochemical and crosslinking data show that COM domains play an unexpected role in properly positioning epimerization (E) and condensation (

A three-dimensional reduced MHD model consistent with full MHD [PDF]
Physics of Plasmas, 2019 Within the context of a viscoresistive magnetohydrodynamic (MHD) model with anisotropic heat transport and cross field mass diffusion, we introduce novel three-term representations for the magnetic field (background vacuum field, field line bending, and field compression) and velocity (E→×B→ flow, field-aligned flow, and fluid compression), which are ...

Angewandte Chemie, EarlyView.A new genetically encoded amino acid is chemically converted into homocysteine (Hcy) under mild conditions to probe and to activate protein active sites. Surprisingly, Hcy can replace cysteine or serine residues in several enzymes. Its potential for a widespread use in proteins is further underlined by rendering Escherichia coli dependent on Hcy ...

Mixed Properties of MHD Waves in Non-uniform Plasmas
Frontiers in Astronomy and Space Sciences, 2019 This paper investigates the mixed properties of MHD waves in a non-uniform plasma. It starts with a short revision of MHD waves in a uniform plasma of infinite extent. In that case the MHD waves do not have mixed properties. They can be separated in Alfv\

Global regularity for the 2D MHD equations with partial hyperresistivity [PDF]
, 2017 This paper establishes the global existence and regularity for a system of the two-dimensional (2D) magnetohydrodynamic (MHD) equations with only directional hyperresistivity.

Neuromodulation: Technology at the Neural Interface, EarlyView., 2021 Abstract Background Refractory chronic migraine (rCM) is a highly disabling condition for which novel safe and effective treatments are needed. Safety and long‐term efficacy of paresthesia‐free high cervical 10 kHz spinal cord stimulation (SCS) were here prospectively evaluated for the treatment of rCM.
