1. The tetrapeptide Ala2-Nph2 (where Nph = p-nitrophenylalanyl) is treated by porcine pepsin to study the mechanism of aminotranspeptidation reactions. 2. The major initial product is Ala2-Nph and the major transpeptidation products are Nph2 and Nph3 accompanied by some Nph

The unnatural amino acid p-nitrophenylalanine (pNO2-Phe) was genetically introduced into proteins in Escherichia coli in response to the amber nonsense codon with high fidelity and efficiency by means of an evolved tRNA/aminoacyl-tRNA synthetase pair from Methanocuccus jannaschii. It was shown

Four-base codon strategy was applied to incorporate a fluorophore-quencher pair into specific positions on a single protein; beta-anthraniloyl-L-alpha,beta-diaminopropionic acid (atnDap) was employed as a fluorophore and p-nitrophenylalanine (ntrPhe) as a quencher. Their positions were directed by the CGGG/CCCG and GGGC/CCCG

A rapid test for detection of p-nitrophenylalanine ammonia-lyase is described. The test is performed by suspending a loopful of bacteria in 0.5 ml of a buffered 1 mM solution of p-nitro-DL-phenylalanine (PNPA). The enzymatic activity is revealed by the formation
