Evidence of carbon monoxide-mediated phase advancement of the yeast metabolic cycle.

Abstract excerpt

Prototrophic strains of budding yeast exhibit robust metabolic cycles during continuous growth under nutrient-limiting conditions. Previous studies revealed periodic fluctuations of aminolevulinic acid, a precursor of heme, indicating that heme biosynthesis is temporally regulated during these metabolic cycles. The enzyme that catabolizes heme, heme oxygenase, was found to be expressed in a highly periodic manner...
