Protein transport: two translocons are better than one.

abstract：:MazF and MazE are components of a chromosomal toxin-antitoxin system of Escherichia coli. In this issue of Molecular Cell, Kamada et al. describe the crystal structure of a MazE/MazF heterohexamer and propose that the mechanism of toxin-antidote recognition is common to other homologous chromosomal and plasmid-borne s...
