Spectroscopic properties of siroheme extracted from sulfite reductases.

Abstract

Siroheme has been extracted from sulfite reductases and its properties in aqueous solution have been investigated by optical absorption, electron paramagnetic resonance (EPR), and magnetic circular dichroism (MDC) spectroscopy. The absorption spectrum of siroheme exhibits a marked pH dependence, and two pK values, 4.2 and 9.0, were determined by pH… (More)
