The first table—the standard table—can be used to translate nucleotide triplets into the corresponding amino acid or appropriate signal if it is a start or stop codon. The second table, appropriately called the inverse, does the opposite: it can be used to deduce a possible triplet code if the amino acid is known.
If amino acids were randomly assigned to triplet codons, there would be 1.5 × 10 84 possible genetic codes. [81]: 163 This number is found by calculating the number of ways that 21 items (20 amino acids plus one stop) can be placed in 64 bins, wherein each item is used at least once. [82]

Protein sequence is typically notated as a string of letters, listing the amino acids starting at the amino-terminal end through to the carboxyl-terminal end. Either a three letter code or single letter code can be used to represent the 22 naturally encoded amino acids, as well as mixtures or ambiguous amino acids (similar to nucleic acid ...
The table below lists the abundance of amino acids in E.coli cells and the metabolic cost (ATP) for synthesis of the amino acids. Negative numbers indicate the metabolic processes are energy favorable and do not cost net ATP of the cell. [12] The abundance of amino acids includes amino acids in free form and in polymerization form (proteins).
Even the smallest proteins contain no fewer than 20 amino acids, making for some pretty long names in their own right; titin, however, is the human body’s largest protein. Total amino acid count ...
Amino acids: ala = alanine; arg = arginine; asn = asparagine; Some pathways produce metabolites that are precursors of more than one pathway. Hence, loss of one of these enzymes will lead to a requirement for more than one amino acid. For example: ilv: isoleucine and valine; Nucleotides: gua = guanine; pur = purines; pyr = pyrimidine; thy ...
