The GAP1Δ2 truncation bypasses lst4Δ to restore Gap1p activity in the plasma membrane. (A) Wild-type (CKY482), lst4Δ (CKY702), and a bul1Δ bul2Δ (CKY701) strain were transformed with pGAP1 (pCK233) or pGAP1Δ2 (pCK234). Three transformants of each strain were cultured in minimal medium (SD Ammonia) at 24°C and assayed for [14C]citrulline uptake. Values are the mean and standard deviation for three transformants for each strain and are expressed as a percentage of the activity in wild-type (gap1Δ [pGAP1]).
