2H5D: 0.9a Resolution Crystal Structure Of Alpha-Lytic Protease Co With A Transition State Analogue, Meosuc-Ala-Ala-Pro-Val Bo
reference: Subangstrom crystallography reveals that short ionic hydrogen bonds, and not a His-Asp low-barrier hydrogen bond, stabilize the transition state in serine protease catalysis., Fuhrmann CN, Daugherty MD, Agard DA, J Am Chem Soc. 2006 Jul 19;128(28):9086-102. PMID: 16834383
