The substrate of the enzyme provides an electron (the first of two single electron transfers) that reduces Compound I to form Compound II.
That is, it acts in an analogous manner to catalase where hydrogen peroxide also reduces Compound I directly in a two-electron reaction to produce dioxygen [32].
Ascorbate is a classical peroxidase substrate that reduces Compound I and Compound II [18] with a single electron whereas bromide is a halogenation substrate that donates two electrons to Compound I and is oxidized to hypobromous acid [17].
The characteristics of reduced compounds are consistent with the electrochemical schemes proposed.
By contrast, in organic falls, like dead whales or wood logs that reach the seafloor, reduced compounds directly originate from the biological degradation of the substrate itself.
We thus demonstrate that microorganisms alone could produce a significant amount of reduced compounds essential for the chemolithotrophic growth of symbiotic or free-living microorganisms.
Partially reduced compounds crystallize within the same structure as fully oxidized ones.
Treatment of chemically (CEH1H2) bleached pulp with laccase showed significant effect on release of chromophores, hydrophobic and reducing compounds.
Further, these two reduced compounds along with six other congeners were produced by chemical or microbiological methods and evaluated against T. cruzi.
In detail, indole and tryptamine derivatives were investigated for their ability to reduce compounds I and II and to affect the chlorinating activity of MPO.
