Table 6.

Mass spectrometric analysis of core-OS of Pst DC3000 ΔwbpL and wild type. Summary of calculated and observed monoisotopic neutral masses [Da] is given. Accuracy of the measurement is stated as Δppm; n.d. = not detected; * detected, but only with <5% of relative intensity to the major base peak.
