The molecule is a glycoside phosphate that is ribostamycin (vistamycin) in which the ribofuranosyl residue is substituted at position 5 by a phosphate group. It is an amino cyclitol glycoside and a glycoside phosphate. It derives from a ribostamycin. It is a conjugate base of a 5''-phosphoribostamycin(2+).
