  • Promoters and usage thereof
    Patent number: 7534602
    Abstract: Promoters and usage thereof. Two promoters, acuF and hsp promoters, comprise the nucleotide sequences of SEQ ID NO: 1 and 2, respectively.
    Type: Grant
    Filed: December 9, 2004
    Date of Patent: May 19, 2009

  • Monacolin K biosynthesis genes
    Patent number: 7482157
    Abstract: Cholesterol inhibitor produced by Monascus, monacolin k, is a secondary metabolite of polyketides. The invention provides probes specific to monacolin k biosynthesis gene cluster. BAC clones having putative monacolin k gene cluster were screened from BAC (bacterial artificial chromosome) library, and sequencing and annotation were performed on these clones. The results show that 2 polyketide synthase (PKS) genes and 7 regulatory genes related to monacolin k synthesis were obtained. Full-length cDNAs of these genes were then obtained by RT-PCR and cloned to expression vectors for the expression of these genes.

  • mutants and their use in preparing fermentation products having blood pressure lowering activity
    Patent number: 7067304
    Abstract: The invention relates to Monascus purpureus mutants, which are useful in the preparation of fermentation products having blood pressure lowering activity with a very low amount of citrinin. The invention also provides a process for preparing the fermentation products having blood pressure lowering activity using the Monascus purpureus mutants, and the use of the fermentation products in lowering blood pressure.
