[7592377] Cloning and characterization of a polyketide synthase gene from Streptomyces fradiae Tu2717, which carries the genes for biosynthesis of the angucycline antibiotic urdamycin A and a gene probably involved in its oxygenation. (J Bacteriol. , 1995)
comment
Blast 4th, id79%, 0.0
Streptomyces fradiae_urdA
Putative ketoacyl synthase

urdEFABCDを含むcosmid purd8をS.lividans TK24へ導入すると、urdamycin抵抗性を獲得。
urdamycin産生株S.fradiae Tu2717染色体から、urdE-C末+urdFABを含むfragment g領域を削除するとurdamycin産生不可。

AA配列解析で、UrdAはPKS gene clustersのbeta-ketoacyl synthasesに高い類似性あり。
UrdAとUrdBはid36%で似ているが、UrdBにはないactive site cysteineをUrdAは持っている。

TcmK ketoacyl synthase or TcmL chain length factorのどちらかを障害してtetracenomycin C非産生にしたStreptomyces glaucescensのmutantで、urdFABを異種性発現したらどちらのmutantも相補され、tetracenomycin Cを産生できた。
