Expression of Vitreoscilla hemoglobin in Gordonia amarae enhances biosurfactant production
The gene (vgb) encoding Vitreoscilla (bacterial) hemoglobin (VHb) was electroporated into Gordonia amarae, where it was stably maintained, and expressed at about 4 nmol VHb g -1 of cells. The maximum cell mass (OD 600) of ...
Evidence for the presence of a second electron donor for the cytoplasmic thioredoxins in the yeast Saccharomyces cerevisiae
In yeast, the cytoplasmic thioredoxin system is composed of NADPH, thioredoxin reductase-1 (TRR1) and 2 thioredoxin genes (TRX1, TRX2). In this study, using yeast knockout mutants for TRR1, TRX1 and TRX2 genes, the role ...
Structure of Halothiobacillus neapolitanus Carboxysomes by Cryo-electron Tomography
Carboxysomes are polyhedral bodies consisting of a proteinaceous shell filled with ribulose 1,5-bisphosphate carboxylase/oxygenase (RuBisCO). They are found in the cytoplasm of all cyanobacteria and some chemoautotrophic ...
Thioredoxin is required for deoxyribonucleotide pool maintenance during S phase
(American Society for Biochemistry and Molecular Biology, 2006-06)
Thioredoxin was initially identified by its ability to serve as an electron donor for ribonucleotide reductase in vitro. Whether it serves a similar function in vivo is unclear. In Saccharomyces cerevisiae, it was previously ...
