(2006) Biochemistry 45: 2114-2121

  • DOI: 10.1021/bi0517133

  • PubMed Abstract: 
  • Atomic resolution (<or=1.2 A) serine protease intermediate structures revealed that the strength of the hydrogen bonds between the enzyme and the substrate changed during catalysis. The well-conserved hydrogen bonds of antiparallel beta-sheet between ...
