The amino acid derivative Boc-Asp-OBzl (Boc=N-butyloxycarbonyl; Asp=aspartic acid; Bzl=benzyl) was functionalized by coupling its carboxylate side chain to dipicolylamine. This yielded the tridentate nitrogen donor ligand Boc-Asp(Dpa)-OBzl (-OBzl). The compound -OBzl contains three different carbonyl groups: a tertiary amide linkage...

The rat liver microsomal vitamin K-dependent carboxylase has been shown to carboxylate the aspartyl residue in N alpha-t-butyloxycarbonylaspartic acid alpha-benzyl ester to a beta-carboxyaspartyl residue. The enzyme also carboxylates aspartyl residues in low molecular weight peptides to beta-carboxyaspartyl residues, but...

Cavity creation is a key to the origin of biological functions. Small cavities such as enzyme pockets are created simply through liner peptide folding. Nature can create much larger cavities by threading and entangling large peptide rings, as learned from...
