Influence of the freezing process upon fluoride binding to hemeproteins [PDF]
Biophysical Journal, 1991 Fluoride association with ferric myoglobins and hemoglobins in aqueous buffers above freezing has been well studied. We chose this reaction to investigate the feasibility of observing titration intermediates and estimating dissociation constants at the freezing temperature by electron paramagnetic resonance spectroscopy at cryogenic temperatures ...

mLife, Volume 3, Issue 1, Page 143-155, March 2024.Abstract In the classical microbial isolation technique, the isolation process inevitably destroys all microbial interactions and thus makes it difficult to culture the many microorganisms that rely on these interactions for survival. In this study, we designed a simple coculture technique named the “sandwich agar plate method,” which maintains ...

Application of Brownian motion theory to the analysis of membrane channel ionic trajectories calculated by molecular dynamics [PDF]
, 1988 This paper shows how Brownian motion theory can be used to analyze features of individual ion trajectories in channels as calculated by molecular dynamics, and that its use permits more precise determinations of diffusion coefficients than would ...

Mechanistics of pH‐Dependent Sulfmyoglobin Formation: Spin Control and His64 Proton Relay
Journal of Chemistry, Volume 2024, Issue 1, 2024.The chemistry of hydrogen sulfide (H2S) has been directed towards physiologically relevant hemeproteins, including myoglobin, hemoglobin, and other similar proteins. Despite substantial efforts, there remains a need to elucidate the mechanism and identify the species involved in the reaction between oxy‐hemeproteins and H2S. Here, we summarize both our

Fast ferrous heme-NO oxidation in nitric oxide synthases. [PDF]
, 2009 International audienceDuring catalysis, the heme in nitric oxide synthase (NOS) binds NO before releasing it to the environment. Oxidation of the NOS ferrous heme-NO complex by O2 is key for catalytic cycling, but the mechanism is unclear.
