英文摘要
Project Summary
This renewal application builds upon a productive collaboration between the Moore
(biosynthesis/natural products chemistry) and Jensen (bioinformatics/microbiology) labs. It seeks to
capitalize on the biosynthetic potential maintained in bacterial genomes by developing three specific
areas of research: 1) Transcriptome guided natural product discovery, 2) Heterologous expression,
production, and characterization of Salinispora secondary metabolites, and 3) Characterization and
exploitation of secondary metabolite regulation. The research will be implemented using the model
marine actinomycete genus Salinispora, for which a unique culture collection and a large number of
genome sequences are available. Comparative transcriptomics will be used to distinguish between
silent and expressed gene clusters, identify key regulatory elements associated with their silencing, and
prioritize clusters for heterologous expression and product characterization. The resulting compounds
will be isolated, characterized, and subjected to biological testing. A workflow has been developed to
target gene clusters that possess the highest probability to yield structurally unique and biologically
active compounds. The mechanistic enzymology associated with unique structural features will be
interrogated and used to inform future structure predictions. This project will specifically address the
regulation of secondary metabolism by testing the effects of salinipostin as an A-factor-like regulator,
identifying the genetic basis for a spontaneous, pigment-less mutant that is reduced in secondary
metabolite production, and introducing regulatory elements whose disruption has been linked to gene
cluster silencing in specific strains. The fundamental goals are to develop new tools and approaches to
identify the natural products encoded in bacterial genomes, obtain new information about the
mechanistic biochemistry responsible for their assembly, and to develop more efficient approaches to
mine bacterial genomes for the structurally unique and biologically active compounds they encode. The
research effectively combines the complimentary expertise of two research groups in the areas of
marine microbiology, biosynthesis, and natural product discovery.
