Evolution of Rhodopseudomonas palustris to degrade halogenated aromatic compounds involves changes in pathway regulation and enzyme specificity

I. Ul Haq, A. Christensen, K. R. Fixen

This paper shows that Rhodopseudomonas palustris evolved to degrade 3-chlorobenzoate through a regulatory mutation and a promiscuous enzyme variant with enhanced specificity.

Selecting a new electron transfer pathway for nitrogen fixation uncovers an electron bifurcating-like enzyme involved in anaerobic aromatic compound degradation

N. M. Lewis, A. Sarne, K. R. Fixen

The paper identifies mutations that redirect electron transfer pathways in Rhodopseudomonas palustris to support nitrogen fixation by repurposing an anaerobic aromatic compound degradation pathway.

Iron oxidation is regulated by the two-component system, RegSR, and plays a role in photolithoheterotrophic growth in Rhodopseudomonas palustris

N. W. Haas, A. Jain, Z. Hying, S. J. Arif, J. A. Gralnick, K. R. Fixen

This study shows RegSR regulates Fe(II) oxidation in R. palustris, enabling photolithoheterotrophic growth using Fe(II) under specific conditions.
