From theCambridge English Corpus This assumes that the key functional group in all human tissues (including brain) ishistidineimidazole. From theCambridge English Corpus Sensor domains were identified as the segment between predicted transmembrane helices associated withhistidinekinase domains. From theCambridge English Corpus The reason for this is easily understood since ammonia forms a hydrogen bond that imidazole (orhistidine) cannot form.
