IUBMB Comments

The enzyme, characterized from the bacterium Staphylococcus aureus, removes D-alanine groups from the teichoic acid produced by this organism, thus modulating the electrical charge of the bacterial surface. The activity greatly increases methicillin resistance in MRSA strains.

The expected taxonomic range for this enzyme is: Staphylococcus aureus
