Many of the Antibiotics and Other Pharmaceutical Agents Isolated from Streptomyces

Question

Many of the antibiotics and other pharmaceutical agents isolated from Streptomyces species are
A) amides.
B) polyketides.
C) thioesters.
D) fatty acids.
E) lipids.

Accepted Answer

Many of the antibiotics and other pharmaceutical agents produced by Streptomyces species are polyketides. Polyketides are a class of natural products synthesized by the polyketide synthase (PKS) pathway. Streptomyces species have a rich repertoire of PKS genes, which allows them to produce a wide range of structurally diverse polyketide-based compounds.
