Due to the lowered pKa of 4-fluorohistidine relative to histidine, peptides and proteins containing this amino acid are potentially endowed with novel properties. We report here the optimized synthesis of 4-fluorohistidine and show that it can efficiently replace histidine in in vitro translation reactions. Moreover, peptides containing 6×-fluorohistidine tags are able to be selectively captured and eluted from nickel resin in the presence of his-tagged protein mixtures.
