amino acid polymer

Proteins are amino acid polymers.

Like any other protein an enzyme is an amino acid polymer with added cofactors and other post-translational modifications.

Often most of the amino acid polymer is indirectly involved with the enzymes function, perhaps providing ancillary structure or connectivity, indirect activity regulation, or molecular identification of the enzyme.

Fox explored the synthesis of amino acids from inorganic molecules, the synthesis of proteinous amino acids and amino acid polymers called "proteinoids" from inorganic molecules and thermal energy, and created what he thought was the world's first "protocells" out of proteinoids and water.
