Analysis of the Involvement of the Isoleucine Biosynthesis Pathway in Photoheterotrophic Metabolism of Rhodospirillum rubrum [PDF]

Frontiers in Microbiology, 2021
Purple non-sulfur bacteria (PNSB) are recognized as a highly versatile group of bacteria that assimilate a broad range of carbon sources. Growing heterotrophically, PNSB such as Rhodospirillum rubrum (Rs.

A singular PpaA/AerR-like protein in Rhodospirillum rubrum rules beyond the boundaries of photosynthesis in response to the intracellular redox state [PDF]

mSystems, 2023
Photosynthesis (PS) in purple non-Sulfur bacteria (PNSB) is strictly controlled to avoid energy consumption and to prevent oxidative stress when oxygen is present. PpsR, a transcriptional repressor encoded in the photosynthesis gene cluster (PGC), is one

Fundamental aspects of sucrose metabolism reveal a trophic link between Rhodospirillum rubrum and Rhodobacter capsulatus [PDF]

mBio
Purple non-sulfur bacteria (PNSB) are well known to have an exceptional metabolic versatility. However, while the growth of PNSB on sugar-rich streams has been extensively explored, their ability to metabolize sugars is poorly understood.

Computational prediction of extracellular loops of the Por39 outer membrane porin of Rhodospirillum rubrum suitable for epitope surface display [PDF]

Computational and Structural Biotechnology Journal, 2023
Outer membrane porins from Gram-negative bacteria are established vehicles for the production of vaccines. Typically, one or more of the extracellular loops of a porin are replaced by a peptide encoding a foreign epitope, and recombinant porin is then ...
