ATCC 29050 strainでdnrI を不活化したら、RHO産生とdaunorubicin (DNR)産生ができなくなり、DNRへの抵抗性が著しく減った。

[PMID: 7868593](1995)
dnrI::aphII mutantでは、DNR生合成におけるearly- and late-acting enzymesの両方をコードする転写物が存在しない。よってdnrI は、直接または間接的にDNR生合成遺伝子のすべてを調節している。

dnrI::aphII and dnrN::aphII strainsでresistance genes=drrAB and drrC転写物は消失。
よって、dnrI はDNR抵抗性の重大なregulatorであり、dnrNはdnrI を通して間接的にその影響を発現する、と示唆される。

dnrI promoter活性を増やすためにはDnrO and DnrN の両方が必要であった。

[PMID: 20529134]や[PMID: 20158521]で、dnrO, dnrN, dnrI, DNRが関与する細胞内DNR濃度維持システムが提唱されている。
dnrI promoterにはDnrNが結合し活性化される。

上記論文と同じ著者ら。
srrY geneはsrrZ mutantで転写されたが、srrZ geneはsrrY mutantで転写されなかった。
SrrY proteinは特異的にsrrZの promoter regionに結合することを確認。
srrZの相補はsrrY mutantにおいてlankamycin産生を回復した。

--->SARP gene srrYはpositive mannerでsecond SARP gene srrZの発現を直接的に制御する。
