Nitrogen-limitation independent control of glnA (glutamine synthetase) expression in Escherichia coli by urea, several amino acids, and post-transcriptional regulation.

K. Urs, P. E. Zimmern, L. Reitzer

This paper shows that glnA expression in uropathogenic E. coli grown in urine is not due to nitrogen limitation but is induced by urea and urinary amino acids through post-transcriptional control.

Extensive transfer of genes for edible seaweed digestion from marine to human gut bacteria

N. A. Pudlo, G. Vasconcelos Pereira, J. Parnami, M. Cid, S. Markert, J. P. Tingley, F. Unfried, A. Ali, A. Campbell, K. Urs, Y. Xiao, R. Adams, D. Martin, D. N. Bolam, D. Becher, , E. C. Martens

The paper shows gut bacteria have extensively adapted to digest seaweed polysaccharides through gene transfer from marine bacteria, revealing widespread metabolic plasticity in the human gut microbiome.
