Abstract:
:Resonance Raman spectra were observed for compound II of horseradish peroxidase A2, and the Fe(IV) = O stretching Raman line was identified at 775 cm-1. This Raman line shifted to 741 cm-1 upon a change of solvent from H2(16)O to H2(18)O, indicating occurrence of the oxygen exchange between the Fe(IV) = O heme and bulk water. The oxygen exchange took place only at the acidic side of the heme-linked ionization with pKa = 6.9.

FEBS LETTERS文献大全abstract::Tyrosyl radicals can catalyze LDL oxidation. In addition to their LDL oxidizing ability, superoxide (O2.-)/nitric oxide (NO.) generate phenoxyl radicals when reacting with tyrosine. Therefore we tested if tyrosine can act as a pro-oxidant in O2.-/NO.-initiated LDL oxidation. When LDL was exposed to O2.-/NO., tyrosine ...
