| 43. | It uses the recommended OECD Guideline 471 tester strains ( histidine auxotrophs and tryptophan auxotrophs ).
|
| 44. | In plants, VirA is a protein histidine kinase which senses certain sugars and phenolic compounds.
|
| 45. | DEPC derivatization of histidines is also used to study the importance of histidyl residues in enzymes.
|
| 46. | The equivalent Serine-Histidine-" Glutamate " triad is used in acetylcholinesterase.
|
| 47. | This Histidine is bound to the Type 2 Cu center responsible for binding and reducing nitrite.
|
| 48. | These histidines all work in conjunction to keep the heptamer from inserting prematurely before endocytosis occurs.
|
| 49. | The zinc coordination sphere is composed of three histidines, one aspartate and two water molecules.
