✦ Synopsis
Cell walls of alkaliphilic Bacillus strain Y-25 are composed of gamma-peptidoglycan and two acidic polymers. An amino sugar, which was a min component of one acidic polymer, did not correspond to any of the commercially available hexosamines. The amino sugar was isolated from the hydrolysate of the acidic polymer, purified, and identified as D-quinovosamine (2-amino-2,6- dideoxy-D-glucose) by 500-MHz NMR spectroscopic analysis and polarimetry.
