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

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

Protein engineering, 16(9), 699-706 (2003-10-16)
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
