ID 3.1.1.103 DE teichoic acid D-alanine hydrolase. CA [(4-D-Ala)-(2-GlcNAc)-Rib-ol-P]n-[Gro-P]m-beta-D-ManNAc-(1->4)-alpha-D- CA GlcNAc-P-peptidoglycan + n H2O = [(2-GlcNAc)-Rib-ol-P]n-[Gro-P]m-beta-D- CA ManNAc-(1->4)-alpha-D-GlcNAc-P-peptidoglycan + n D-alanine. CC -!- The enzyme, characterized from the bacterium Staphylococcus aureus, CC removes D-alanine groups from the teichoic acid produced by this CC organism, thus modulating the electrical charge of the bacterial CC surface. CC -!- The activity greatly increases methicillin resistance in MRSA CC strains.
