Proposed interaction between LytC and PG substrate attached to teichoic acid chains. (a) Details of the active site of LytC with the bound PG fragment (green sticks). Choline molecule attached to the site formed by repeats p7 and p8 is about 9 Å away from the PG bound to the active site. Loop Lc (residues 364–381) is labeled. (b) Computational model of PG-TA moiety bound to LytC active site based on the crystal structure of the LytC–choline–PG ternary complex and the NMR structure of a TA chain from S. pneumoniae R6 strain15. The docked choline moieties are represented as spheres.
