  • By use of techniques described recently for lac permease [Roepe, P.D., & Kaback, H.R. (1989) Proc. Natl. Acad. Sci. U.S.A. 86, 6087], the melibiose permease from Escherichia coli, another polytopic integral plasma membrane protein, has been purified in a metastable soluble form after overexpression of the melB gene via the T7 RNA polymerase system [9].
