This protein may use the morpheein model of allosteric regulation.

The analysis of the complete primary sequence of a protein using only one protease is usually not possible.

Genetics Institute's scientists have produced a biochemical "library" of 250 proteins using this information.

For example, certain proteins may use alternative initiation (start) codons not normally used by that species.

The current focus is proteins using WikiProteins as knowledge portal.

The standard code allows cells to manufacture proteins using only 20 amino acids.

Genetic systems have also been developed which allow the production of recombinant proteins using E. coli.

Another approach is to describe the hydrophobic features of the protein using turns in the main-chain atoms.

It has also been shown that under certain circumstances it is possible to reconstruct the 3D coordinates of a protein using its contact map.

The transport mechanism which proteins use to progress through the Golgi apparatus is not yet clear; however a number of hypotheses currently exist.
