G-Protein-coupled receptors: Decoding mixed signals

February 15th, 2017 by Thomas J Gardella

Nature Chemical Biology 13, 247 (2017). doi:10.1038/nchembio.2316

Author: Thomas J Gardella

A new mechanism of functional crosstalk between two distinct G-protein-coupled receptors (GPCRs)—the parathyroid hormone receptor (PTHR) and β2-adrenergic receptor (β2 Ar)—that occurs at the level of G protein βγ subunits and a specific adenylyl cyclase isoform is identified. This crosstalk augments cAMP signaling by the PTHR from endosomes, and thus promotes the actions of PTH ligands in bone target cells.

Structure and specificity of a permissive bacterial C-prenyltransferase

February 6th, 2017 by Sherif I Elshahawi

Nature Chemical Biology 13, 366 (2017). doi:10.1038/nchembio.2285

Authors: Sherif I Elshahawi, Hongnan Cao, Khaled A Shaaban, Larissa V Ponomareva, Thangaiah Subramanian, Mark L Farman, H Peter Spielmann, George N Phillips, Jon S Thorson & Shanteri Singh

This study highlights the biochemical and structural characterization of the L-tryptophan C6 C-prenyltransferase (C-PT) PriB from Streptomyces sp. RM-5-8. PriB was found to be uniquely permissive to a diverse array of prenyl donors and acceptors including daptomycin. Two additional PTs also produced novel prenylated daptomycins with improved antibacterial activities over the parent drug.
