Summary:PROBLEM TO BE SOLVED: To genetically create a microorganism which can efficiently produce reveromycin A and a synthetic intermediate thereof; to provide a method for efficiently obtaining a spiroketal ring-containing compound; and to provide a novel anticancer agent, an antifungal agent, and a therapeutic agent for bone disorders.SOLUTION: The invention relates to a Streptomyces bacteria having productivity of reveromycin A or a synthetic intermediate thereof, wherein the expression of a revQ gene encoding an amino acid sequence of sequence ID number 36 or an amino acid sequence having 80% or more identity with the amino acid sequence is modified to increase compared with a parent strain, and thereby the productivity is increased more than the parent strain.SELECTED DRAWING: Figure 2 【課題】リベロマイシンAおよびその合成中間体を効率よく生産することのできる微生物を遺伝子組み換えにより創製すること、スピロケタール環含有化合物を効率よく得るための方法を提供すること、新規抗癌剤、抗真菌剤および骨疾患治療剤を提供することを課題とする。【解決手段】リベロマイシンA またはその合成中間体の生産能を有するストレプトマイセス属細菌であって、配列番号36のアミノ酸配列または該アミノ酸配列と80%以上の同一性を有するアミノ酸配列をコードするrevQ遺伝子の発現が親株と比較して増大するように改変され、それにより前記生産能が該親株よりも向上したストレプトマイセス属細菌。【選択図】図2
