摘要:
According to the present invention, the E . coli mutant strain having chromosomal DNA that is at least 470 kbp shorter than that of a wild-type E . coli strain exhibits such a property that the number of the cells after a certain period of culture is greater than a wild-type strain. Thus, by culturing the mutant strain in a medium so as to generate and accumulate a useful substance in the culture, a useful substance such as proteins, peptides, amino acids, nucleic acids, vitamins, saccharides, organic acids, and lipids can be efficiently produced.
摘要:
The present invention relates to a protein derived from a microorganism belonging to the genus Bacillus, which has an activity of hydroxylating a compound represented by the formula (I-a): wherein R 1 represents a hydrogen atom, a substituted or unsubstituted alkyl, or an alkali metal, and R 2 represents a substituted or unsubstituted alkyl or a substituted or unsubstituted aryl, or a ring-closed lactone form thereof; a DNA encoding said protein; and a recombinant DNA comprising said DNA.
