A stereochemical mechanism for the open-to-closed transition that involves the electrostatic neutralization of two active site arginine residues by the negative charges of the incoming substrate, a large change in the backbone (φ,ψ) conformational angles of two key glycine residues, and the entropy-driven burial of a stretch of hydrophobic residues on the N-terminal helix is proposed.

We have fitted over 160 electronic absorption spectra of over 95 aromatic compounds and some other substances with lognormal distribution curves to evaluate the shapes of the bands. The compounds…

The analysis establishes that in all species a proton remains on either the phenolic oxygen or the imine nitrogen, and suggests that the latter may, in fact, be a quinonoid form, either alone or in rapid equilibrium with the Schiff base.

X-ray diffraction studies show that the crystals with erythro-beta-hydroxy aspartate and alpha-methylaspartate are isomorphous with those of both alpha and beta subforms of the native enzyme.
