Summary
N-terminus of purified HisH was sequenced by Klem and Davisson (1993), and the fMet is not clipped. [More information is available at EcoGene: EG10450]. Imidazole glycerol phosphate synthase (HisFH) is a heterodimer that carries out the fifth step in histidine biosynthesis, as well as generating aminoimidazole carboxamide ribonucleotide, an intermediate in purine nucleotide biosynthesis. [More information is available at EcoCyc: EG10450].
