pimaricin biosynthetic gene clusterの報告。
PimE: cholesterol oxidase

pimE productは、cholesterol oxidasesととても高い相同性がある。
Brevibacterium sterolicumのcholesterol oxidase_ChoB(id 58.9%)
Streptomyces sp. strains A19249_ChoM(id 79.9%)
Streptomyces sp. strains SA-COO_ChoA(id 82.6%)

PimEはpolyketide productのoxidative modification stepsにたぶん関与するが、正確な機能は測定されていない。

[PMID: 17379143](2007)
pimEは機能的なcholesterol oxidaseをコードし、pimaricin生合成にも関与する。PimE不活化はpimaricinを非産生にし、それはPimEやその他のcholesterol oxidaseで回復できる。よって、これらのcholesterol oxidasesはpolyene生合成のためのsignaling proteinsとして働きうると示唆される。

ただ、他の解析済のpolyene macrolides生合成に関するgene clusterにcholesterol oxidasesは見つかっていない（と述べられているが、rimocidin/CE-108 clusterにid91% RimDあり） 。
