Solving the scalability issue in quantum-based refinement: Q|R#1

An interaction-based fragmentation scheme for solving the issue of scalability in quantum refinement has been developed, implemented in the Q|R software and validated on an amyloid cross-β spine (PDB entry 2ona).

Molecular architectures of benzoic acid-specific type III polyketide synthases

The structures of biphenyl synthase, of biphenyl synthase complexed with benzoyl-CoA and of benzophenone synthase are compared with a chalcone synthase homolog. These structures reveal that benzoic acid-specific type III polyketide synthases contain distinct structural elements, including a novel pocket, which underlies their evolutionary emergence.

A standardized technique for high-pressure cooling of protein crystals

A standardized technique for high-pressure cooling of protein crystals has been developed that encompasses all steps from crystal retrieval to automated mounting of the sample at the synchrotron. A wide chemical space for sample cooling has been tested. Amorphous ice was formed in more than 89% of the solutions.
