An LH1–RC photocomplex from an extremophilic phototroph provides insight into origins of two photosynthesis proteins

Communications Biology, 2022
The cryo-EM structure of the unusual light-harvesting 1–reaction center (LH1–RC) complex from Rpi. globiformis, the most acidophilic anaerobic purple bacteria, is presented, characterized and compared to other photosynthetic bacteria.

Engineering Photosynthetic Bioprocesses for Sustainable Chemical Production: A Review

Frontiers in Bioengineering and Biotechnology, 2021
Microbial production of chemicals using renewable feedstocks such as glucose has emerged as a green alternative to conventional chemical production processes that rely primarily on petroleum-based feedstocks.

Regulation of photosynthetic gene expression in purple bacteria [PDF]

Microbiology, 1998
Purple phototrophic bacteria have the ability to capture and use sunlight efficiently as an energy source. In these organisms, photosynthesis is carried out under anaerobic conditions. The introduction of oxygen into a culture growing phototrophically results in a rapid decrease in the synthesis of components of the photosynthetic apparatus and a ...

Structural studies and functional engineering of NanX: an anhydro‐sialic acid transporter from Escherichia coli

FEBS Open Bio, EarlyView.
Biophysical characterisation shows that NanX, a membrane transport protein from the major facilitator superfamily (MFS), forms both monomers and dimers after purification. AlphaFold modelling and substrate docking provide information on residues likely involved in substrate recognition for NanX and another MFS member, NanT.

Purple Urine Bag Syndrome [PDF]

Journal of Clinical and Diagnostic Research, 2015
Purple urine bag syndrome (PUBS) is a rare disorder seen in elderly persons, wherein the urinary bag and the tubing turn in to purple colour. It is usually seen in patients who are on urinary catheters for a long time.

Heterotropic regulation and negative homotropic cooperativity

FEBS Open Bio, EarlyView.
We identified a structural module common to some proteins that couple negative cooperativity with heterotropic regulation, two features that rarely coexist. These proteins are ring‐like and present an ordered asymmetry whereby noncontacting subunits are symmetric, and their tertiary structure differs from that of contacting subunits.

Characterization of redox-active cysteine residues of persulfide-responsive transcriptional repressor SqrR

Communicative & Integrative Biology, 2017
We recently identified the novel persulfide sensor SqrR that functions as a master regulator of sulfide-dependent gene expression in the purple photosynthetic bacterium Rhodobacter capsulatus. SqrR binds to the promoter regions of target genes to repress

Effects of chitinase-transgenic (McChit1) tobacco on the rhizospheric microflora and enzyme activities of the purple soil

Plant, Soil and Environment, 2013
In order to evaluate the bio-security of genetically modified (GM) plants in the purple soil, we carried out a pot experiment about rhizospheric microflora at different development stages of a chitinase-transgenic (McChit1) tobacco (T-Chit), a plasmid ...
