Figure 1. SDS-PAGE of purified deletion mutants
A: Purified leader mutant 51 (LM51). B: Purified deletion mutant 51 (DM51) before and after removal of the His-tag. The estimated molecular mass for each mutant is correct, with DM51 slightly more mobile than LM51 as determined by the molecular weight standards.
