摘要:
The present invention provides an isolated polynucleotide comprising the kstD promoter from Rhodococcus erythrypolis. The polynucleotide can very advantageously be used as a controllable transcription activator. Said controlling function can be provided by providing said isolated polynucleotide with a nucleotide sequence encoding a transcription regulator of said promoter. In the present invention, such a transcription regulator may be externally induced, such as by introduction of steroidal compounds. In an alternative embodiment of the present invention the isolated polynucleotide may comprise the kstR gene or a homologue or a functional part thereof as the transcription regulator of the kstD promoter.

摘要:
A method is described to construct genetically modified strains of steroid degrading micro-organisms wherein the method comprises inactivation of at least one gene involved in methylhexahydroindanedione propionate degradation. Strains with (multiple) inactivated steroid degrading enzyme genes according to the invention can be used in the accumulation of steroid intermediates. Accumulation products are for example 3aα-H-4α(3′-propionic acid)-7aβ-methylhexahydro-1,5-indanedione (HIP), 3-hydroxy-9,10-secoandrosta-1,3,5(10)-triene-9,17-dione (3-HSA), 1,4-androstadiene-3,17-dione (ADD) and 3aα-H-4α(3′-propionic acid)-5α-hydroxy-7aβ-methylhexahydro-1-indanone-δ-lactone (HIL).
