Preparation and spectroscopic properties of Co III -isobacteriochlorins: relationship to the cobalt-containing proteins from Desulphovibrio gigas and D. desulphuricans

Abstract

It is concluded that prosthetic groups of the cobalt-containing proteins from Desulphovibrio gigas and D. desulphuricans are cobalt isobacteriochlorins because their absorption spectra exactly match those of authentic cobalt isobacteriochorins now prepared and characterized.
