Conserved Distal Loop Residues in the Hsp104 and ClpB Middle Domain Contact Nucleotide-binding Domain 2 and Enable Hsp70-dependent Protein Disaggregation

Morgan E. DeSantis, Elizabeth A. Sweeny, David Snead, Eunice H. Leung, Michelle S. Go, Kushol Gupta, Petra Wendler, James Shorter
2013 Journal of Biological Chemistry  
Conclusion: Distal loop does not project out into solution and Hsp104 and ClpB are tuned differently for Hsp70 collaboration.  ...  How Hsp104 and ClpB coordinate polypeptide handover with Hsp70 to dissolve disordered protein aggregates is unknown.  ...  Isolated MD Does Not Interact with Hsp70 or Inhibit Disaggregation in Trans-Another possibility for how specific distal loop mutations impair Hsp70 collaboration is that mutation in this region disrupts  ...

Tuberculosis (TB) control programs use whole-genome sequencing (WGS) of Mycobacterium tuberculosis (Mtb) for detecting and investigating TB case clusters.  ...  However, the variable and sometimes long duration of latent infection, combined with uncertainty in the Mtb mutation rate during latency, can complicate interpretation of WGS results.  ...  to disease, allowing the TB program to conclude a recent TB case is attributable to reactivation of latent infection.  ...

Alejandra Gutiérrez-Estrada, Jesús Ramírez-Santos, María del Gómez-Eichelmann
2014 SpringerPlus  
Escherichia coli stationary-phase (SP) cells contain relaxed DNA molecules and recover DNA supercoiling once nutrients become available.  ...  In these cells, the reactivation of DNA gyrase, which is a DNA topoisomerase type IIA enzyme, is responsible for the recovery of DNA supercoiling.  ...  We also thank L Camarena and C Domenzain for assistance in preparing the Figures and I Pérez-Montfort for editorial assistance.  ...
