Help:Tag
Tags are small functional sequences of amino acids. Thus far, our functional tags fall into the categories of transport out of cell, and degradation tags (ie. LVA tags)
Tags are often found on Reporter parts and other types of Protein Coding parts.
Our future plans for tags involve building proteins using biobricks. To read more on this project, visit Ira Phillip's work on biobrick modification.
LVA Tag
Leucine+Valine+Alanine is an amino acid sequence which can be added to the end of a protein. This sequence marks the protein for immediate degradation by the cell.
