<dc:description>Macrolides constitute a large class of natural&#xd;
metabolites produced by giant multifunctional&#xd;
enzymes in a process resembling fatty acid&#xd;
biosynthesis. Like f atty acids, macrolides and other&#xd;
polyketides are assernbled by decarboxylative&#xd;
condensations of simple carboxylic acids. But while&#xd;
fatty acid intermediates are fully reduced, macrolide&#xd;
and other polyketide intermediates suffer the&#xd;
suppression of reduction or dehydration reactions at&#xd;
given biosynthetic steps. In the last years much&#xd;
progress has 'been made in our understanding of the&#xd;
linear and modular organisation of the gene clusters,&#xd;
and the enzymes encoded by them, responsiblefor...</dc:description>
