Members of the matrix metalloproteinase (MMP) family have biological functions that are central to human health and disease, and MMP inhibitors have been investigated for the treatment of cardiovascular disease, cancer and neurodegenerative disorders.
Post-PKS enzyme complexes
This review highlights the protein–protein interactions between type II post-PKS tailoring enzymes with an emphasis on gilvocarcin and mithramycin.
Is it time for artificial intelligence to predict the function of natural products based on 2D-structure
One of chemistry's grand challenges is to find a function for every known metabolite. We explore the opportunity for artificial intelligence to provide rationale interrogation of metabolites to predict their function.
3-Ketoacyl-ACP synthase (KAS) III homologues and their roles in natural product biosynthesis
KAS III-like enzymes play a significant role in natural product biosynthesis through C–C, C–O, and/or C–N bond formation.
Diversification of polyketide structures via synthase engineering
We present examples of polyketide structure diversification along with a perspective on the present and future of polyketide synthetic biology.
Using Drosophila as a platform for drug discovery from natural products in Parkinson's disease
The review provides an overview of discovery of new drug leads from natural extracts using Drosophila as a screening platform to evaluate the therapeutic potential of phytochemicals against Parkinson's disease.
Recent advances in the genome mining of Aspergillus secondary metabolites (covering 2012–2018)
This review covers advances made in genome mining SMs produced by Aspergillus nidulans, Aspergillus fumigatus, Aspergillus niger, and Aspergillus terreus in the past six years (2012–2018).
