Perosamine (or GDP-perosamine) is a mannose-derived 4-aminodeoxysugar produced by some bacteria.

==Biological role== N-acetyl-perosamine is found in the O-antigen of Gram-negative bacteria such as Vibrio cholerae O1, E. coli O157:H7 and Caulobacter crescentus CB15. The sugar is also found in perimycin, an antibiotic produced by the Gram-positive organism Streptomyces coelicolor var. aminophilus.
