Why do all polypeptide chains start with methionine?
Because the nucleotide that codes for methionine also is the "start" signal, so whenever a polypeptide starts it uses the exact same code (AUG) so methionine must start every polypeptide chain.
Is methionine the same compound as methianine?
No, methionine and methianine are not the same compound. It is possible that "methianine" is a misspelling or a different term for methionine. Methionine is an essential amino acid that is found in proteins, while "methianine" does not have a recognized meaning or chemical structure.
Why methionine is n formylated in prokaryotes but not in eukaryotes?
i think formylated methionine is more efficient recognizer of AUG
What can I eat to get methionine?
High levels of methionine is found in sesame seeds, Brazil nuts, fish, meats and some other plant seeds; methionine is also found in cereal grains. Most fruits and vegetables contain very little of it. Most legumes also has low quantity of methionine.
What amino acid has AUG?
METHIONINE
What is the start codon and what amino acid does it code for?
AUG. The amino acid methionine. Bases read; adenine-uracil-guanine
What does atgaaagcctatgcacca code for?
Methionine; Proline; Serine and STOP.
Why do all polypeptide chains start with methionine?
Because the nucleotide that codes for methionine also is the "start" signal, so whenever a polypeptide starts it uses the exact same code (AUG) so methionine must start every polypeptide chain.
Why methionine is the first amino acid in every growing polypeptide?
Start Codon Methionine's code is AUG which is also a start codon causing initiation of translation.
When a protein is synthesized what amino acid is always the first amino acid that is positioned during any protein synthesis?
"AUG" actually corresponds to a region of code on mRNA and is NOT an amino acid. The tRNA that has the anticodon 5' CAU 3' and recognizes AUG is a tRNA charged with Methionine. Therefore, methionine is the first amino acid incorporated into a growing polypeptide. Note this is true for only eukaryotes, prokaryotes have N-formyl methionine as their first amino acid.
Is methionine the same compound as methianine?
No, methionine and methianine are not the same compound. It is possible that "methianine" is a misspelling or a different term for methionine. Methionine is an essential amino acid that is found in proteins, while "methianine" does not have a recognized meaning or chemical structure.
What amino acid is encoded by the initiation codon AUG?
The amino acid that is encoded by the initiation codon AUG is methionine. It is the only amino acid which is specified by just one codon.
What portion of tsp is 62.5 mg of L methionine?
what portion of tsp is 12 mg of l methionine
Why methionine is n formylated in prokaryotes but not in eukaryotes?
i think formylated methionine is more efficient recognizer of AUG
How many different mrna correspond to methionine?
Only one mRNA codon codes for Methionine - AUG.
What can I eat to get methionine?
High levels of methionine is found in sesame seeds, Brazil nuts, fish, meats and some other plant seeds; methionine is also found in cereal grains. Most fruits and vegetables contain very little of it. Most legumes also has low quantity of methionine.
Which two amino acids contain a sulfur atom?
The sulfur containing amino acids that are found in proteins are cysteine and methionine.
