The plasma membrane ferrireductase activity of Saccharomyces cerevisiae is partially controlled by cyclic AMP.

The Biochemical journal - 1 Dec 1991

Lesuisse E, Horion B, Labbe P, Hilger F

Abstract excerpt

The plasma-membrane-bound ferrireductase activity of ras1 and ras2 mutants of Saccharomyces cerevisiae is not induced in response to iron limitation. This phenotype was suppressed by the bcy1 mutation in ras2 but not in ras1 mutants. The cellular haem content of ras-1-bearing strains decreased dramatically when cells were grown in semi-synthetic medium (low yeast extract content), which could account for their...
