| 41. | Glutaminyl-tRNA synthetase belongs to the class-I aminoacyl-tRNA synthetase family.
|
| 42. | The active site of the synthetase is modified to accept only the novel amino acid.
|
| 43. | It is formed by glutamate cysteine ligase and used by glutathione synthetase to form glutathione.
|
| 44. | L-Canavaninosuccinic acid is cleaved to form L-canavanine by argininosuccinic acid synthetase.
|
| 45. | The enzyme aminoacyl tRNA synthetase " charges " the tRNA molecules with the correct amino acids.
|
| 46. | Thus, glutamate tRNA synthetase charges tRNA-glutamine ( tRNA-Gln ) with glutamate.
|
| 47. | All of these reactions take place inside the aminoacyl-tRNA synthetase specific for that tRNA.
|
| 48. | In one family mutations in the mitochondrial histidyl tRNA synthetase have been described as the cause.
|
| 49. | This enzyme is also called "'nondiscriminating asparaginyl-tRNA synthetase " '.
|
| 50. | Indeed, SIRT3 deacetylates and activates the mammalian mitochondrial acetyl-coA synthetase ( AceCS2 ).
