    摘要： Nucleoside-5′-triphosphates and phosphoramidites which carry a residue absorbing in the long wavelength region, preferably a carbocyanine group of the general formula (I), on the base portion or on the phosphorus atom in which R1 and R2 each denote hydrogen or together form a phenyl residue; R3 denotes hydrogen if linkage with the nucleotide is via the R4 position or it denotes a —NHCS— group if linkage with the nucleotide is via the R3 position; both R4 and R5, or R5, alone denote an alkylsulfonyl group with n being a number from 3 to 5 or R4 represents a —NHCS— group with n being a number from 3 to 8, as well as the use of the compounds to label, detect and sequence nucleic acids.

    摘要： Process for the production of oligonucleotides of formula II, in which the exocyclic amino groups of the bases adenine, guanine, cytosine, 7-deazaadenine and 7-deazaguanine carry N-phenylacetyl groups, are used for oligonucleotide synthesis, wherein in a first step a starting nucleotide is bound to a solid carrier, subsequently the desired oligonucleotide is synthesized by stepwise coupling with appropriately activated further monomeric nucleotide building blocks of the general formula I with the above-mentioned meanings, if desired, trivalent phosphorus is oxidized to pentavalent phosphorus during and after the synthesis, the oligonucleotide is cleaved from the carrier and the 5' protecting groups are cleaved off. The phenylacetyl functional groups that protect exocyclic NH.sub.2 groups of the bases can be cleaved off in a mild way with penicillin amidohydrolase (EC 3.5.1.11).

    摘要： A mutant of PQQ-dependent soluble glucose dehydrogenase (s-GDH; EC 1.1.5.2) is provided with improved specificity for glucose as compared to maltose, having a substitution of threonine at position 348 by either glycine, alamine or serine, wherein said mutant additionally comprises, at least one mutation for improving the stability of the mutant and one or more mutation(s) for improving the affinity of the mutant to glucose, and/or one or more mutation(s) for further improving the specificity of the mutant for glucose as compared to maltose, and wherein position 348 correspond to the amino acid positions known from the A. calcoaceticus s-GDH wild-type sequence. Also disclosed are genes encoding such mutant s-GDH, and different applications of these s-GDH mutants, particularly for determining the concentration of glucose in a sample.
