摘要:The complete sequence of the gene cluster for the monensin type I polyketide synthase, from S. cinnamonensis, is provided. Thus variant polyketides containing monensin-derived elements can be genetically engineered. Furthermore there are novel features, e.g. a regulatory protein mon RI, which are of wide utility.

摘要:Erythromycins, particularly ones with novel C-13 substituents R1 (e.g. C3-C6 cycloalkyl or cycloalkenyl groups) are prepared by fermenting suitable organisms in the presence of R1CO2H. A preferred organism is Saccharopolyspora erythraea preferably containing an integrated plasmid capable of directing synthesis of desired compounds.
