In Saccharomyces cerevisiae maltose utilization requires a functional MAL locus, each composed of three genes: MALR (gene 3) encoding a regulatory protein, MALT (gene 1) encoding maltose permease and MALS (gene 2) encoding
maltase
. We show that constitutive activation of the RAS/protein kinase A pathway severely reduces growth of MAL1 strains on maltose. This may be a consequence of reduction in MALT mRNA, reduced Vmax and increased catabolite inactivation of the MALT-encoded maltose transporter in the MAL1 strain. Mutations in the GGS1/
TPS1
gene, which restricts glucose influx and possibly affects signalling, relieve carbon catabolite repression on both
maltase
and maltose permease and reduce maltose permease inactivation.
