B. Pfanzagl et al., N-ACETYLPUTRESCINE AS A CHARACTERISTIC CONSTITUENT OF CYANELLE PEPTIDOGLYCAN IN GLAUCOCYSTOPHYTE ALGAE, Journal of bacteriology, 178(23), 1996, pp. 6994-6997
Cyanelle peptidoglycan from the glaucocystophyte algae Glaucocystis no
stochinearum and Cyanoptyche gloeocystis was investigated by high-perf
ormance liquid chromatography of muropeptides, supported by matrix-ass
isted laser desorption-ionization mass spectrometry. The peptidoglycan
s of both species are modified with N-acetylputrescine, as has been de
monstrated for cyanelle peptidoglycan of Cyanophora paradoxa.
