  Characterisation of stress protein LysU. Enzymic synthesis of diadenosine 5′,5‴-P¹,P⁴-tetraphosphate (Ap₄A) analogues by LysU

  摘要：

  The stress protein LysU (lysyl tRNA synthetase) has been purified from a recombinant strain of Escherichia coli expressing the plasmid pXLys5, and kinetically characterised. Preparative syntheses of analogues of the biologically important molecule diadenosine 5',5'''-P-1,P-4-tetraphosphate (Ap(4)A) are then achieved in good yield by enzyme catalysis, using purified LysU.

  Recombinant Escherichia coli lysyl-tRNA synthase (LysU) has been previously utilised in the production of stabile, synthetic diadenosine polyphosphate (ApnA) analogues. Here we report on the extended use of a new recombinant histidine residue-tagged LysU as a tool for highly controlled phosphateAphosphate bond formation between nucleotides, avoiding the need for complex protecting group chemistries. Resulting high yielding tandem LysU-based biosynthetic-synthetic/synthetic-biosynthetic strategies emerge for the preparation of varieties of ApnA analogues directly from inexpensive natural nucleotides and nucleosides. Analogues so formed make a useful small library with which to probe ApnA activities in vitro and in vivo leading to the discovery of new, potentially potent biopharmaceuticals active against chronic pain and other chronic, high-burden disease states.
