Rubredoxins

01/01/2022 - "Thus, we quantified the strength of Co(II)-thiolate bonds in rubredoxin with a rupture force of ∼140 pN, revealing that it is a mechanostable chemical bond. "
01/01/2022 - "To prove this, we used atomic force microscopy-based single-molecule force spectroscopy (AFM-SMFS) to directly measure the rupture force of Co(II)-thiolate bond in Co-substituted rubredoxin (CoRD). "
05/27/2020 - "Instead, the rupture mechanism of rubredoxin is far more complex than previously thought and requires more than just a hydrogen bond network."
05/27/2020 - "While structural anisotropy as well as the contribution of angle bendings in the FeS4 unit have a significant influence on the mechanical properties of rubredoxin, these factors are insufficient to explain the experimentally observed low rupture force. "
05/27/2020 - "The surprisingly low rupture force and remarkable mechanical anisotropy of rubredoxin have been known for several years. "

10/01/2004 - "Treponema pallidum (Tp), the syphilis spirochete, expresses the gene for a superoxide reductase called neelaredoxin, having the iron protein rubredoxin as the putative electron donor necessary to complete the catalytic cycle. "

01/01/2021 - "In Mycobacterium tuberculosis, oxidative and acidic stresses as well as iron starvation induce rubredoxins expression. "

01/01/2021 - "Genes that exhibited significantly higher transcript levels during rabbit infection included those encoding multiple ribosomal proteins, several prominent membrane proteins, glycolysis-associated enzymes, replication initiator DnaA, rubredoxin, thioredoxin, two putative regulatory proteins, and proteins associated with solute transport.
