POLYKETID-SYNTHASEN MIT VERÄNDERTER SPEZIFITÄT, IHRE HERSTELLUNG UND VERWENDUNG

摘要

Biosyntheses of compounds whereof at least portions are polyketides produced by means of polyketide synthase (PKS) enzyme complexes are carried out after specific alterations have been made within the acyltransferase (AT) domains of the PKSs. Particular motifs in or near the substrate binding pocket are disclosed, such that alterations therein affect substrate specificity.
