High impact information on dsbA

  • But so far, neither in vitro nor in vivo phenotype could be identified in a staphylococcal dsbA mutant, leaving its physiological role unknown [1].
  • After fusion to pelB, dsbA or ompT signal peptides no recombinant product could be obtained in the periplasm using the T7 promoter [2].
