Offloading Role of a Discrete Thioesterase in Type II Polyketide Biosynthesis.

abstract：:Emerging zoonotic viral diseases remain a challenge to global public health. Recent surveillance studies have implicated bats as potential reservoirs for a number of viral pathogens, including coronaviruses and Ebola viruses. Caliciviridae represent a major viral family contributing to emerging diseases in both human ...
