Abstract: | Derivatives of N-acyl-D-mannosamine differing in the N-acyl-side chain can be metabolically converted into neuraminic acids with corresponding N-acyl side chains. In the present study we show the in vivo modulation of sialic acids in membrane-bound dipeptidyl peptidase IV (CD 26) from rat liver after administration of N-propanoyl-D-mannosamine. Treatment of rats with this unphysiological precursor resulted in an incorporation of N-propanoylneuraminic acid into N-linked glycans of dipeptidyl peptidase IV. |
