"SpletWe identified two OM lipoproteins, LpoA and LpoB, which are absolutely required for the in vivo function of PBP1A and PBP1B, respectively. Each Lpo protein interacts specifically with its cognate PG synthase and stimulates its TPase in vitro. LpoB, like PBP1B, is recruited to the divisome but also to the lateral wall, whereas LpoA concentrates ... " - Pbp1a function
