Dependence of tyrosine oxidation in highly oxidizing bacterial reaction centers on pH and free-energy difference.

Biochemistry - 12 Oct 2004

Kálmán L, Narváez A J, LoBrutto R, Williams J C, Allen J P

Abstract excerpt

The pH and temperature dependences of tyrosine oxidation were measured in reaction centers from mutants of Rhodobacter sphaeroides containing a tyrosine residue near a highly oxidizing bacteriochlorophyll dimer. Under continuous illumination, a rapid increase in the absorption change at 420 nm was observed because of the formation of a charge-separated state involving the oxidized dimer and reduced primary...
