ERQC machinery as broad spectrum Antivirals

All viruses depend on host cell proteins for replication. Denying viruses’ access to the function of critical host proteins can result in antiviral activity against multiple virus families. In particular, small-molecule drug candidates which inhibit the α-glucosidase enzymes of the endoplasmic reticulum (ER) translation quality control (QC) pathway [a-GluI] have demonstrated broad-spectrum antiviral activities and low risk

 

 

for development of viral resistance. Crystal structures of Ct α-GluI in complex with UV-4, UV-5, and EB-0159 revealed extensive interactions with all four enzyme subsites and provided insights into the catalytic mechanism. Identification of ER Ct α-GluI as a surrogate for mammalian α-GluI will accelerate the structure-guided discovery of broad-spectrum antivirals. The study also highlights Ct as a source of thermostable eukaryotic proteins, such as ER α-Glu I, that lack orthologs in bacterial or archaeal thermophiles.
