Do cytochromes function as oxygen sensors in the regulation of nitrate reductase biosynthesis?

Abstract

The observation that oxygen represses nitrate reductase biosynthesis in a hemA mutant grown aerobically with or without delta-aminolevulinic acid indicates that cytochromes are not responsible for nitrate reductase repression in aerobically grown cells.
