Deletion Analysis of the Escherichia coli Taurine and Alkanesulfonate Transport Systems

Eichhorn, Eric, Van Der Ploeg, Jan R., Leisinger, Thomas

The Escherichia coli tauABCD and ssuEADCB gene clusters are required for the utilization of taurine and alkanesulfonates as sulfur sources and are expressed only under conditions of sulfate or...

Transformation of Isopropylamine to l-Alaninol by Pseudomonas sp. Strain KIE171 Involves N-Glutamylated Intermediates

De Azevedo Wäsch, Susana I., Van Der Ploeg, Jan R., Maire, Tere, Lebreton, Alice, Kiener, Andreas, Leisinger, Thomas

Pseudomonas sp. strain KIE171 was able to grow with isopropylamine or l-alaninol [S-(+)-2-amino-1-propanol] as the sole carbon source, but not with d-alaninol. To investigate the hypothesis that...

Regulation of Bacteriocin Production in Streptococcus mutans by the Quorum-Sensing System Required for Development of Genetic Competence

Van Der Ploeg, Jan R.

In Streptococcus mutans, competence for genetic transformation and biofilm formation are dependent on the two-component signal transduction system ComDE together with the inducer peptide pheromone...
