[The nitrosophenol system of iron metabolism regulation in actinomycetes]
Abstract:
Iron-containing o-nitrosophenol compounds have been isolated from 64 strains of microorganisms of 18 species. The analysis of author's and published data allowed to divide iron-containing microbial compounds into two physiological groups: ferri-ionophores, i. e. compounds participating in active iron transfer, and those immobilizing iron at increase in its content in medium up to 10(-4)-10(-2) M. O-nitrosophenol pigments were found to belong to the latter group. A scheme of participation of o-nitrosophenol compounds in regulation of iron metabolism in actinomycetes has been proposed.

Oxidation of Phenols to Quinones
o-hydroxy phenols are oxidized to o-quinones and p-hydroxy phenols to p-quinones. Such redox reactions involve the transfer of two electrons and two protons. The reversible redox property is crucial in...
