| 21. | Methionine itself can be loaded either onto tRNA fMet or tRNA Met.
|
| 22. | Then methionine aminopeptidase ( MAP ) removes the residue from the chain.
|
| 23. | As with many oil seeds, the protein is low in methionine.
|
| 24. | The methionine residue can be further removed by the enzyme methionine aminopeptidase.
|
| 25. | The methionine residue can be further removed by the enzyme methionine aminopeptidase.
|
| 26. | Aspartate can be converted into lysine, asparagine, methionine and threonine.
|
| 27. | Importantly, only HemN utilizes S-adenosyl Methionine ( SAM ).
|
| 28. | Methionine synthase eventually becomes inactive due to the oxidation of its cofactor.
|
| 29. | In humans, methionine is an essential amino acid that must be ingested.
|
| 30. | Instead, it is biosynthesized from methionine via a multi-step process.
