Nitroxides are broadly used as molecular probes and labels in biophysics, structural biology, and biomedical research. Resistance of a nitroxide group bearing an unpaired electron to chemical reduction with low-molecular-weight antioxidants and enzymatic systems is of critical importance for these

Terminally protected homopeptides of tert-leucine, from the dimer to the hexamer, co-oligopeptides of tert-leucine in combination with alpha-aminoisobutyric acid or glycine residues up to the hexamer level, and simple dipeptides representing known scaffolds for catalysts in asymmetric organic reactions were

The unique reactivity pattern elicited by the crowded tert-butyl group is highlighted by summarising characteristic applications. Starting from the use of this simple hydrocarbon moiety in chemical transformations, via its relevance in Nature and its implication in biosynthetic and biodegradation
Stabilizing and destabilizing effects of placing beta-branched amino acids in protein alpha-helices.

Biochemistry, 33(40), 12022-12031 (1994-10-11)
In order to gain greater insight into the effects of beta-branched amino acids on protein alpha-helices, hydrophobic amino acids with varying degrees of beta-branching, including the fully beta-substituted L-2-amino-3,3-dimethylbutanoic acid (ADBA), were incorporated into the protein T4 lysozyme. The unnatural

Penicillin G acylase (PGA) from Kluyvera citrophila immobilized on Amberzyml was used for enantioselective hydrolysis of N-phenylacetylated-DL-tert-leucine (N-Phac-DL-Tle) to produce L-tert-leucine (L-Tle). The effects of various organic cosolvents on hydrolysis of N-Phac-DL-Tle have been investigated in aqueous-cosolvent medium. It was
