Legionella pneumophila


Legionaminic acid (LEG) is an essential lipopolysaccharide component exclusively synthesized by Legionella pneumophila.

The Azide-functionalized Legionaminic acid precursor pLEG-Azide (Man2NAc4NAc6-N3) provides an attractive approach for the specific detection of Legionella pneumophila in living cultures: It is cell-permeable, intracellularly processed and incorporated instead of its natural counterpart.

The resulting Azide-functionalized lipopolysaccharides can subsequently be detected via Cu(I)-catalyzed or Cu(I)-free Click Chemistry that offers the choice to introduce a Biotin group (via Alkynes of (Desthio)Biotin or DBCO-containing (Desthio)Biotin, respectively) for subsequent purification tasks or to introduce fluorescent group (via Alkynes of Fluorescent Dyes or DBCO-containing Fluorescent Dyes , respectively) for subsequent microscopic imaging.
