Proteins containing unnatural amino acids have immense potential in biotechnology and medicine. We prepared several histidine analogues including a novel histidine analogue, beta-(1,2,3-triazol-4-yl)-DL-alanine. These histidine analogues were assayed for translational activity in histidine-auxotrophic Escherichia coli strain UTH780. We observed that

In contrast to wild-type cells, it was found that triazole-alanine-resistant mutants of Methanococcus voltae excreted histidine, proline, phenylalanine, and tyrosine in various combinations. These results suggest that a form of general amino acid biosynthetic control may operate in this methanogen.

The effect of the substitution of the active site histidine 48 by the unnatural 1,2,4-triazole-3-alanine (TAA) amino acid analogue in porcine pancreas phospholipase A2 (PLA2) was studied. TAA was introduced biosynthetically using a his-auxotrophic Escherichia coli strain. To study solely

A simple synthetic approach to racemic N-tert-butyloxycarbonyl-2-methyl-3-(1H-1,2,4-triazol-1-yl)alanine (5) in four steps and 68% overall yield starting from oxazoline derivative 1 is reported. This synthesis involves the alkylation of 1H-1,2,4-triazole with an O-tosyloxazoline derivative, followed by an oxazoline ring-opening reaction and

The only histidine residue in the H31N-H137N double mutant of phage lambda lysozyme (lambdaL), at position 48, was biosynthetically replaced by the analogue 1,2,4-triazole-3-alanine (Taz), the basicity of which is 3 pKa units lower. A histidine-auxotrophic strain was grown to
