FIG. 4.

S. pombe liz1Δ mutants are complemented by uracil, β-alanine, and ureidopropionate. Wild-type S. pombe cells or cells with deletions in liz1⁺ or in liz1⁺ and pan6⁺ were spotted on plates containing no pantothenate. All cells tested here were ura-positive. The indicated compounds were present at a concentration of 1 mM. Growth was recorded after 3 days at 30°C.
