| 1 | D-histidine is a necessary amino acid for man and animal. | |
| 2 | The results indicated that the modification of cysteine and histidine residues had no effect on the activity. | |
| 3 | Our finding implicates functional importance of histidine in exchange of arginine at amino acid 481 of transferrin receptor 2 in iron homeostasis. | |
| 4 | The conjugation of histidine onto helper lipid enhances transgene expression contrast with unmodified liposomes. | |
| 5 | Irreversibly inhibits trypsin but not chymotrypsin by alkylating the histidine residue in the active site of the enzyme. |
