WebProtein expression in bacteria is quite simple; DNA coding for your protein of interest is inserted into a plasmid expression vector that is then transformed into a bacterial cell. Transformed cells propagate, are induced to produce your protein of interest, and then lysed. Protein can then be purified from the cellular debris.
