Bacillosamine (2,4-diamino-2,4,6-trideoxy-D-glucose), a rare amino sugar, was discovered fifty years ago as a result of the follow up of a chance observation made during studies of polypeptide synthesis by a Bacillus subtilis strain later renamed Bacillus licheniformis. In the following decades this amino sugar was almost completely ignored, although it was found in a number of bacterial polysaccharides and other metabolites. Recently there has been a burst of interest in bacillosamine when it was found to be a link glycan in eubacterial glycoproteins. In this retrospective, I review the chance discovery of bacillosamine, its structural determination and its biosynthesis.
*Dedicated to Roger W. Jeanloz, mentor and friend, and glycobiology pioneer, in whose laboratory and under whose guidance I discovered bacillosamine, on the occasion of his 90th birthday, November 3, 2007.
