A process for the production of a glycoconjugate by N-glycosylation of a protein or peptide comprising the sequence D/E-X-N-X-S/T, wherein each X is the same or different and is any natural amino acid other than proline, wherein the process comprises reacting the protein or peptide with a polyisoprenyl pyrophosphate of formula (I), or a salt thereof, in the presence of PglB: (I) to produce the glycoconjugate comprising the protein or peptide having a saccharide [SI] linked to the asparagine in the sequence D/E-X-N-X-S/T. Polyisoprenylpyrophosphates used as substrates in the biocatalytic process are also provided, as well as certain glycoconjugates.

The novel C dialdehyde compound which can be efficiently utilized in the synthesis of carotenoid compounds based on the sulfone chemistry, the preparation method of the same, and the expeditious and practical synthetic processes for lycopene and β-carotene by the use of the above novel compound are disclosed. The syntheses of lycopene and β-carotene are characterized by the processes of the coupling reaction between two equivalents of geranyl sulfone or cyclic geranyl sulfone and the above C dialdehyde, the functional group transformation reactions of the diol in the resulting C 40 coupling products to X's (either halogens or ethers), and the double elimination reactions of the functional groups of the benzenesulfonyl and X to produce the fully conjugated polyene chain of the carotenoids.
