| Outline of Final Research Achievements |
Mycoplasma is one of the simplest bacteria having no rigid cell walls and lipopolysaccharides (LPS). Instead, they utilize either alpha- or beta-glycolipids in cytoplasmic membrane. Also in our preceding studies, we have reported alpha-glycolipid antigens (GGPLs) in M. fermentans as well as beta-linked ones (GGLs)in M. pneumoniae. In the present study, we applied our glycosylation methods for the library assembly of GGLs homologues carrying variable acyl chains and examined their chemical behaviors. The chemical library involved a deuterium labeled GGL homologue for simultaneous MS detection of natural GGLs. It involved also an acetyl (C2) homologue for the study on molecular dynamics (MD). The assembled chemical library enabled us to elucidate the best GGLs homologue (GGLS C18) for the ELISA diagnosis of Mycoplasma pneumoniae infection and their possibility to make a crown ether-like ionophore around the non-reducing terminal end in their dynamic three dimensional (3D) structures.
