A heat shock promoter drives expression of a mutated form of Mad which contains the amino acid replacement T312V.
MadT312V.hs partially rescues Madk00237
Expression of MadT312V.hs using heat shock partially rescues the lethality of Madk00237 mutants, with the rescue efficiency being increased with more frequent heat shocks. The degree of rescue with MadT312V.hs is more effective than that seen with Madhs.PK under the same conditions.
