Effect of peptidoglycan modifying enzymes PgdA and Adr on hydrolysis of pneumococcal cell walls in the presence of lysozyme.

<p>Hydrolysis of peptidoglycan (50 µg/ml), purified from the wild-type (WT) strain or the defined mutants indicated with lysozyme (100 µg/ml) from A) chicken egg (+L) or B) human (+Hu L). Representative experiment showing percentage of hydrolysis based on the optical density (OD 600 nm) of each reaction at time 0 min.
