0 any of the chemical substances found in plants and animals that combine to make protein (= a substance necessary for the body to grow) -- 氨基酸
Ammonium was the major source of mineral nitrogen, and glutamine was the most abundant free amino acid.
The position of the amino acid in the protein is indicated on the left side.
They were divided into different groups according to amino acid sequence similarities.
The focus of the book is less on biological issues than on algorithms (although alignment of nucleotide and amino acid sequences are only superficially covered).
It could also simply reflect a problem of amino acid saturation that it is difficult to correct for.
The structure proposed here is based on primary amino acid sequence and has yet to be confirmed by crystallographic studies.
The scale bar represents the phylogenetic distance expressed as expected amino acid substitutions per site.
One subunit (top right) has been displaced to display the location of the amino acid substitutions (in cyan and white).
