    • Substrate residues are labeled according to the nomenclature of Schechter and Berger, 1967, where residues extending N-terminal from the cleaved bond are P1, P2, etc.; those extending C-terminally are P1′, P2′, etc. The corresponding enzyme binding pockets are labeled S1, S1′, etc.

    • X-ray crystallographic values for donor-hydrogen distances are shorter than true internuclear distances due to displacement of the hydrogen electron density toward the donor atom, and librational effects.

    • 9). Regardless, the His57-boroVal hydrogen atom in our structure is located on His57 and is not at all displaced towards boroVal; therefore, the His57-boroVal hydrogen bond is not a LBHB by either definition.
