LC/MS analysis of the mannose capping of LAM in <i>capA</i>-expressing <i>M</i>. <i>abscessus</i> strains either proficient or deficient in LAM succinylation.

Shown in bold letters are the relative percentages of total (including, unmodified and covalently modified) Ara4, Ara5 and Ara6 oligoarabinosides released upon Cellulomonas gelida endoarabinanase digestion of LAM from M. abscessus WT and ΔsucT expressing or not capA (from pVV16-MT1671) and the individual representation (expressed as percentages) of unmodified and covalently modified oligoarabinosides within each group. Suc, succinate; Manx, mannoside cap containing x mannose residues.
