3.1 Table of standard amino acid abbreviations and properties. ... Amino acids are organic compounds that contain both amino and carboxylic acid functional groups. [1]
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.
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).
Amino acids are listed by type: Proteinogenic amino acid; Non-proteinogenic amino acids This page was last edited on 5 January 2020, at 17:16 (UTC). Text is ...
Sequences are expected to be represented in the standard IUB/IUPAC amino acid and nucleic acid codes, with these exceptions: lower-case letters are accepted and are mapped into upper-case; a single hyphen or dash can be used to represent a gap character; and in amino acid sequences, U and * are acceptable letters (see below). Numerical digits ...
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]

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 ...
