| 1. | Lactacystin modifies the amino-terminal threonine of specific proteasome subunits.
|
| 2. | High levels of threonine result in low levels of homoserine synthesis.
|
| 3. | It catalyzes its autophosphorylation on serine / threonine and tyrosine residues.
|
| 4. | Cytokine-inducible kinase is a putative serine / threonine kinase.
|
| 5. | Phosphatases from the Cdc25 family dephosphorylate both the threonine and the tyrosine.
|
| 6. | Phosphorylating a serine or threonine residue on its target substrate.
|
| 7. | They bind the ATPases'C-terminus at a conserved threonine.
|
| 8. | The structural feature that governs this autoinhibition is the Threonine 286 residue.
|
| 9. | Aspartate can be converted into lysine, asparagine, methionine and threonine.
|
| 10. | These threonine-insensitive forms of HSD are used in nutritional value.
