The invention provides Bacillus host cell deficient in the production of a neutral protease and of a alkaline protease which host cell comprises a nucleic acid construct, wherein the nucleic acid construct comprises a polynucleotide encoding a compound of interest or encoding a compound involved in the synthesis of a compound of interest operably linked to a promoter sequence allowing for expression of the polynucleotide in the host cell, wherein the promoter comprises a bacteriophage promoter sequence, more preferably a bacteriophage SPO1 promoter sequence. Said host cell can advantageously be used in a method of production of a compound of interest.
本发明提供了缺乏中性
蛋白酶和
碱性蛋白酶生产的芽孢杆菌宿主细胞,该宿主细胞包括核酸构建体,其中核酸构建体包括编码感兴趣的化合物或编码参与合成感兴趣的化合物的多核苷酸,该多核苷酸与启动子序列可操作地连接,允许多核苷酸在宿主细胞中表达,其中启动子包括噬菌体启动子序列,更优选噬菌体
SPO1启动子序列。所述宿主细胞可用于相关化合物的生产方法中。
