ABSTRACT: To better understand the structural basis of enzyme specificity, the structures of complexes formed
between a-lytic protease, an extracellular serine protease of Lysobacter enzymogenes, and five inhibitory
peptide boronic acids (R2-boroX, where R2is methoxysuccinyl-Ala-Ala-Pro-and boroX is the a-aminoboronic
acid analogue of Ala, Val, Ile, Norleu, or Phe) have been studied at high resolution by X-ray crystallography.
