Methods to Assess Autophagy and Chronological Aging in Yeast.

abstract：:The diverse structures of polyketide natural products are reflected by the equally diverse polyketide biosynthetic enzymes, namely polyketide synthases (PKSs). Three major classes of PKSs are known-noniterative type I PKSs, iterative type II PKSs and acyl carrier protein-independent type III PKSs, each of which consis...
