Endohexosaminidase M: exploring and exploiting enzyme substrate specificity.
Oxazoline saccharides have been synthesised and tested as glycosyl donors for endohexosaminidase M (Endo M)-catalysed glycosylation of a GlcNAcAsn glycosyl amino acid. Endo M-catalysed glycosylation is not limited to donors containing the Manβ(1-4)GlcNAc linkage, and replacement of the core mannose...

| Summary: | Oxazoline saccharides have been synthesised and tested as glycosyl donors for endohexosaminidase M (Endo M)-catalysed glycosylation of a GlcNAcAsn glycosyl amino acid. Endo M-catalysed glycosylation is not limited to donors containing the Manβ(1-4)GlcNAc linkage, and replacement of the core mannose unit by glucose promotes irreversible glycosylation. In this case, use of a modified oxazoline donor as a transition-state mimic allows enzyme-catalysed synthesis, but precludes product hydrolysis. © 2006 Wiley-VCH Verlag GmbH and Co. KGaA. |
