The insect pathogen Serratia marcescens Db10 uses a hybrid non-ribosomal peptide synthetase-polyketide synthase to produce the antibiotic althiomycin [PDF]
, 2012 There is a continuing need to discover new bioactive natural products, such as antibiotics, in genetically-amenable micro-organisms. We observed that the enteric insect pathogen, Serratia marcescens Db10, produced a diffusible compound that inhibited the

Iterative polyketide biosynthesis by modular polyketide synthases in bacteria [PDF]
Applied Microbiology and Biotechnology, 2015 Modular polyketide synthases (type I PKSs) in bacteria are responsible for synthesizing a significant percentage of bioactive natural products. This group of synthases has a characteristic modular organization, and each module within a PKS carries out one cycle of polyketide chain elongation; thus each module is non-iterative in function.

Isolation of pigment cell specific genes in the sea urchin embryo by differential macroarray screening [PDF]
, 2003 New secondary mesenchyme specific genes, expressed exclusively in pigment cells, were isolated from sea urchin embryos using a differential screening of a macroarray cDNA library. The comparison was performed between mRNA populations of embryos having an

Profile of PKS and NRPS Gene Clusters in the Genome of Streptomyces cellostaticus NBRC 12849T
Fermentation, 2023 Polyketides and nonribosomal peptides are major secondary metabolites in members of the genus Streptomyces. Streptomyces cellostaticus is a validly recognized species and the type strain produces cellostatin. However, little is known about whether it has
