Papers of the month

2011

• July 2011
  • Domínguez-Escobar et al. from Rut Carballido-Lopez' lab and Garner et al. report that movement of actin-like filaments is driven by the peptidoglycan elongation machinery. Both papers suggest that the MreB-like filaments serve to restrict the mobility of the peptidoglycan synthesizing machinery
    
  • Relevant SubtiWiki pages: Rut Carballido-Lopez, David Rudner, MreB, MreBH, Mbl, MreC, MreD, RodA, RodZ, cell shape, cell wall synthesis

• June 2011
  • Oppenheimer-Shaanan et al. from Sigal Ben-Yehuda's lab report that cyclic di-AMP acts as a secondary messenger that couples DNA integrity with progression of sporulation
