Identification of the Flavobacterium johnsoniae cysteate-fatty acyl transferase required for capnine synthesis and for efficient gliding motility.

Sulfonolipids (SLs) are bacterial lipids that are structurally related to sphingolipids. Synthesis of this group of lipids seems to be mainly restricted to Flavobacterium, Cytophaga and other members of the phylum Bacteroidetes. These lipids have a wide range of biological activities: they can induce multicellularity in choanoflagellates, act as von Willebrand factor receptor antagonists, inhibit DNA polymerase, or function as tumour suppressing agents.
