The flavohemoglobin Yhb1 is a new interacting partner of the heme transporter Str3

open access: yesMolecular Microbiology, Volume 122, Issue 1, Page 29-49, July 2024.
A new mechanism for Yhb1 (orange) heme‐dependent activation involves direct interaction with the cell‐surface heme transporter Str3 (blue) in the presence of exogenous heme (red). Upon exposure to nitric oxide (˙NO), the expression of yhb1+ is induced, as its promoter is liberated from Fep1 repression (violet).

Cultivating the uncultured: Harnessing the “sandwich agar plate” approach to isolate heme‐dependent bacteria from marine sediment

open access: yesmLife, 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 ...

Mechanistics of pH‐Dependent Sulfmyoglobin Formation: Spin Control and His64 Proton Relay

open access: yesJournal 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

Influence of the freezing process upon fluoride binding to hemeproteins [PDF]

open access: yesBiophysical 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 ...
