Table 1 Relative amounts of PBPs in recombinant L.monocytogenes strains

From: Re-evaluation of the significance of penicillin binding protein 3 in the susceptibility of Listeria monocytogenes to β-lactam antibiotics

Protein Amount of PBP protein a
  L. monocytogenes pAKB L. monocytogenes pAKB-lmo1438
PBP1 4.48 (± 0.45) 4.21 (± 0.81)
PBP2 1b 0.96 (± 0.08)
PBP3 1.66 (± 0.15) 5.78 (± 0.47)c
PBP4 1.67 (± 0.05) 3.2 (± 0.34)c
PBP5 12.05 (± 0.42) 12.01 (± 1.03)
  1. a Average results of densitometric analysis of three independent fluorograms.
  2. b Values were normalized to the band intensity of PBP2 from L. monocytogenes pAKB, which was assigned the value of 1.
  3. c Indicates band with intensity significantly different (P < 0.05; acc. to Student's t-test) from the corresponding band of the control strain.
