Sulfmyoglobin formation pathway upon reaction of oxy-myoglobin and hydrogen sulfide
Myoglobin (Mb) binds oxygen with high affinity as a low spin singlet complex and thus functions as an oxygen storage protein. Quantum chemical calculations of oxy-Mb models with hydrogen sulfide (H2S) in the active site ...
Structural aspects and chemical species involved in the hemeperoxidases catalytic oxidation of hydrogen sulfide by hydrogen peroxide and oxygen
Hydrogen sulfide (H2S) has gained attention since it is implied in human physiological functions with potential therapeutically effects. Furthermore, H2S interacts with physiologically important hemeproteins such as ...
Surface characterization of chemically modified electrodes with gold nanoparticles and (His)6-rHbI from Luciana pectinata for H2S Detection
The recombinant polyhistidine-tagged hemoglobin I ((His)6-rHbI) from bivalve Lucina pectinata is an ideal biocomponent for a hydrogen sulfide (H2S) biosensor due to its high affinity for H2S. Nowadays it is clear that H2S ...
