Abstract

O2, NO, and CO are substrates, products, and/or modulators in many enzymatic reactions including O2 respiration, denitrification, N2 fixation, and methanogenesis. Over the last decade, O2, NO, and CO have been reported to act as signaling molecules in the control of several distinct biological functions. Here, the heme-based mechanisms of CO sensing by the bacterial homodimeric CooA and the mammalian heterodimeric NPAS2-BMAL1 transcriptional factors are reviewed, and the signal transduction pathways are discussed.
