  • Shawn Reeves studied both Biochemistry and Nanotechnology Engineering at the University of Waterloo, where he graduated with Dean's Honours for the former in 2022. (catalysiscongress.com)
  • Additionally, our team has developed surface active agents built from protein blocks that localize to condensate interfaces and enable tunable control of condensate size. (upenn.edu)
  • Most recently, we developed an approach to engineer a vast universe of new proteins with tunable shapes (Pan et al. (ucsf.edu)
  • Overall, this study provides the most comprehensive structure-reactivity relationship to date on heteroaryl sulfones and highlights 2-sulfonylpyrimidine as a synthetically tractable and protein compatible covalent motif for targeting reactive cysteines, expanding the arsenal of tunable warheads for modern covalent ligand discovery.

  • The field of tissue engineering is constantly evolving as it aims to develop bioengineered and functional tissues and organs for repair or replacement. (mdpi.com)
  • Our work suggests that a high degree of structural plasticity is required to tolerate the diverse sequences, and the dynamic ensemble allows sampling of conformers competent to engage receptors. (umich.edu)
  • To select an appropriate affimer, screening is done to find suitable reagents for the target protein. (news-medical.net)
  • That's a big change from conventional sequencing procedures that require expensive reagents and machines. (ieee.org)
  • I assessed the accuracy of several algorithms using cross-validation by identity, a new benchmark strategy which explicitly models the variation in distances between query sequences and the closest entry in a reference database. (peerj.com)
