ABSTRACT The Tol proteins are involved in the outer membrane stability of gram-negative bacteria. The C-terminal domain of TolA was mutagenized to identify residues important for its functions. The isolation of suppressor mutants of tolA mutations in the tolB gene confirmed an interaction between TolAIII and the N-terminal domain of TolB.

ABSTRACT IS16 is a thiol-sensitive, Q-deficient mutant strain of Escherichia coli. Here, we show that IS16 harbors a mutation in the ubiG gene encoding a methyltransferase required for two O-methylation steps of Q biosynthesis. Complementation of IS16 with either ubiG or ubiX K-12 reverses this phenotype, suggesting that UbiX may interact with UbiG.
