Several optimization strategies we commonly use are:
1/ Change the promoter to make the vector sequence more suitable for E. coli expression system.
2/ Try to insert genes into the E.coli's(or other expression system) genome to increase expression yield.
3/ Use a variety of BL21 strains (especially modified strains) to express proteins, such as some deleted protease genes' subtype.
