A chemocentric view of the natural product inventory

August 18th, 2015 by Christopher T Walsh

Nature Chemical Biology 11, 620 (2015). doi:10.1038/nchembio.1894

Author: Christopher T Walsh

As the identification of previously undetected microbial biosynthetic pathways burgeons, there arises the question of how much new chemistry is yet to be found. This, in turn, devolves to: what kinds of biosynthetic enzymatic transformations are yet to be characterized?

Methods: A small-molecule SMASh hit

Authors: Jeffrey Hannah & Pengbo Zhou

There are many techniques that can be employed to control gene expression at the post-translational level. However, a novel system called SMASh (small molecule–assisted shutoff), which allows for chemically-induced degradation of target proteins, presents some distinct advantages.

A wide variety of enzymatic pathways that produce specialized metabolites in bacteria, fungi and plants are known to be encoded in biosynthetic gene clusters. Information about these clusters, pathways and metabolites is currently dispersed throughout the literature, making it difficult to exploit. To facilitate consistent and systematic deposition and retrieval of data on biosynthetic gene clusters, we propose the Minimum Information about a Biosynthetic Gene cluster (MIBiG) data standard.

Looking for logic

Improved tools and expanding knowledge are enabling new insights into the biochemical basis, ecological roles and promising applications of natural product biosynthesis.

Protein degradation: Prime time for PROTACs

August 18th, 2015 by Raymond J Deshaies

Nature Chemical Biology 11, 634 (2015). doi:10.1038/nchembio.1887

Author: Raymond J Deshaies

PROTACs are heterobifunctional small molecules that simultaneously bind a target protein and a ubiquitin ligase, enabling ubiquitination and degradation of the target. Major progress in developing potent and specific PROTACs has recently been reported, invigorating prospects for novel PROTAC-based therapies.
