    摘要: The invention provides modified nucleotide or nucleoside molecule comprising a purine or pyrimidine base and a ribose or deoxyribose sugar moiety having a removable 3′-OH blocking group covalently attached thereto, such that the 3′ carbon atom has attached a group of the structure —O-Z wherein Z is any of —C(R′)2-O—R″, —C(R′)2-N(R″)2, —C(R′)2-N(H)R″, —C(R′)2-S—R″ and —C(R′)2-F, wherein each R″ is or is part of a removable protecting group; each R′ is independently a hydrogen atom, an alkyl, substituted alkyl, arylalkyl, alkenyl, alkynyl, aryl, heteroaryl, heterocyclic, acyl, cyano, alkoxy, aryloxy, heteroaryloxy or amido group, or a detectable label attached through a linking group; or (R′)2 represents an alkylidene group of formula ═C(R′″)2 wherein each R′″ may be the same or different and is selected from the group comprising hydrogen and halogen atoms and alkyl groups; and wherein said molecule may be reacted to yield an intermediate in which each R″ is exchanged for H or, where Z is —C(R′)2-F, the F is exchanged for OH, SH or NH2, preferably OH, which intermediate dissociates under aqueous conditions to afford a molecule with a free 3′OH; with the proviso that where Z is —C(R′)2-S—R″, both R′ groups are not H.

    摘要: The invention relates to constructs comprising a nucleic acid binding protein and a surface. At least one native accessible cysteine residue is removed from the binding protein. The binding protein is attached to the surface via one or more accessible cysteine residues. The removal of other accessible cysteine residues from the protein allows control attachment to the surface. The constructs can be used to generate transmembrane pores having a nucleic acid binding protein attached thereto. Such pores are particularly useful for sequencing nucleic acids. The enzyme handles the nucleic acid in such a way that the pore can detect each of its component nucleotides by stochastic sensing.
