Penicillin resistance and tolerance has been an increasing threat to the treatment of pneumococcal pneumoniae. However, no penicillin tolerance-related genes have been claimed. Here we show that a major heat shock protein ClpL/HSP100 could modulate the expression of a cell wall synthesis enzyme PBP2x, and subsequently increase cell wall thickness and penicillin tolerance in Streptococus pneumoniae.
