2.A.1.25.2
Cell wall degradation product (peptides and glycopeptides including N-acetylglucosaminyl β-1,4-anhydro-N-acetyl-muramyl-tri or tetra-peptide) as well as penicillin derivative uptake porter, AmpG (Cheng and Park 2002). The AmpG permease is also required for AmpC beta-lactamase induction (Chahboune et al. 2005; Park and Uehara 2008). AmpG mediates a dynamic relationship between serine beta-lactamase induction and biofilm-formation (Mallik et al. 2018).
