Abstract

The Sml1p protein oligomerization was characterized by ESI-FTICR-MS. Sml1p was expressed in E. coli BL21DE3pLys bacteria by an expression plasmid DNA encoding SML1. Using the expression plasmid DNA as a template, C17S SML1 mutant was made by a PCR based site-directed mutagenesis kit, Quikchange, and the mutant protein was expressed in the same manner. The results show that Sml1p forms oligomers through non-covalent interaction, and in non-reducing conditions, a small amount of wild type Sml1p was eluted with apparent mass of 50kD, which is close to mass of tetramer (48kD).
