Question
which of the following modified amino acids is incorporated during translation rather than being modified post-translationally? y-carboxyglutamate, phosphoserine, selenocysteine, 4-hydroxyproline, n-e-acetyllysine which of the following modified amino acids is incorporated during translation rather than being modified post-translationally? y-carboxyglutamate, phosphoserine, selenocysteine, 4-hydroxyproline, n-e-acetyllysine which of the following modified amino acids is incorporated during translation rather than being modified post-translationally? y-carboxyglutamate, phosphoserine, selenocysteine, 4-hydroxyproline, n-e-acetyllysineExplanation / Answer
answer : selenocysteine
explanation :
two new standard biogenic amino acids other than the standard 20 were discovered rather more recently they are incorporated into proteins during transiliation rather than as a result of post-translational modification. selenocysteine the 21 st amino acid was discovered in 1986 and arises through the modification of serine after it attachment to t-RNA' most other non-standard amino acids results from post translational modification of standard amino acids with whole protein chain subsequent to ribosomal processing .
