    摘要: Linking sequence which modulate cross-talk between modules of Type I polyketide synthases have been identified. Thus, arbitrarily chosen modules can be mixed and matched by supplying the appropriate linkers to obtain desired polyketide synthases and new polyketides. The modules are provided suitable linkers so that the polyketide chain is passed from one module to the other in the correct sequence. Synthetic peptides which mimic linkers can be used to inhibit the synthesis of polyketides. Kinetic channeling, both intrapolypeptide and interpolypeptide, of diketide intermediates in a Type I polyketide synthase can occur. In addition, the role of protein-protein interactions between a donor acryl carrier protein (ACP) domain and a downstream ketosynthase (KS) domain and enzyme-substrate interactions in the channeling of intermediates between polyketide synthase modules and between a polyketide synthase module and a NRPS module has been identified.

    摘要: Modified PKS gene clusters which produce novel polyketides in an efficient system in a host cell or in a cell free extract are described. The novel polyketides result from the incorporation of diketides of the formula wherein A is a moiety that activates the diketide, and at least one of R1 and R2 is a substituent other than that natively occurring in the diketide normally processed by the modified PKS cluster. The polyketides may also be glycosylated to provide antibiotics.
