Multimerization-defective variants of dodecameric secretin PulD.

Research in microbiology - 1 Jan 2000

Guilvout Ingrid, Nickerson Nicholas N, Chami Mohamed, Pugsley Anthony P

Abstract excerpt

The C-terminal core domain of the secretin PulD from Klebsiella oxytoca forms heat-resistant dodecameric complexes within less than 10min in an Escherichia coli in vitro transcription-translation system containing liposomes, and is toxic when made in the cytoplasm without a signal peptide. Random mutagenesis of DNA encoding this region of PulD revealed that amino acid changes throughout almost its entire length...
