[PMID: 1878971](1991)
actinorhodin biosynthetic gene clusterのactII 領域の解析論文。

actII-ORF4導入でactinorhodin産生増加。
actII-ORF4破壊でactinorhodin非産生。
actII mutant strainでは、act生合成遺伝子転写物がなくなったり減ったりした(unpublished)。
actIII geneの転写にはactII 領域が同時に存在することが必要(Hallam et al. 1988)。
actII-ORF4にはTTA codonが含まれているため、翻訳にはBldAが必要。

[PMID:7683365](1993) abstract
対数期→静止期でactII-ORF4転写(↑)
同時に、actIII, actVI-ORF1転写(↑)、actinorhodin産生(↑)

対数期でmulticopy plasmidによってactII-ORF4を増やすと、
→actII-ORF4 mRNA(↑)
→actIII 転写、actinorhodin産生をもたらす
