Oligodeoxyribonucleotides 83-104 replication protein Escherichia coli 13-16 9454579-3 1998 Using fluorescence resonance energy transfer and stopped-flow techniques, we have examined the mechanism of ss-oligodeoxynucleotide binding to preformed Rep dimers in which one binding site is occupied by a single-stranded oligodeoxynucleotide, while the other site is free (P2S dimer). Oligodeoxyribonucleotides 111-131 replication protein Escherichia coli 153-156 8918597-4 1996 Stopped-flow experiments show that the dissociation rate of a fluorescent ss oligodeoxynucleotide bound to one subunit of the dimeric Rep helicase is stimulated by ssDNA binding to the other subunit, and that the rate of this ssDNA exchange reaction is further stimulated approximately 60-fold upon ATP hydrolysis. Oligodeoxyribonucleotides 77-97 replication protein Escherichia coli 134-137 8816749-1 1996 To examine the coupling of ATP hydrolysis to helicase translocation along DNA, we have purified and characterized complexes of the Escherichia coli Rep protein, a dimeric DNA helicase, covalently crosslinked to a single-stranded hexadecameric oligodeoxynucleotide (S). Oligodeoxyribonucleotides 243-263 replication protein Escherichia coli 148-151 8652567-2 1996 Using stopped-flow fluorescence, we have determined a minimal kinetic mechanism for this reaction in which Rep monomer (P) binds to ss oligodeoxynucleotides (dN(pN)15) (S) by a two-step mechanism to form PS*, which can then dimerize with P to form P2S as indicated: [reaction in text]. Oligodeoxyribonucleotides 135-156 replication protein Escherichia coli 107-110 1658335-3 1991 Complexes of Rep protein were formed with short single-stranded and duplex hairpin oligodeoxynucleotides with lengths such that only a single Rep monomer could bind per oligodeoxynucleotide (i.e. 2 Rep monomers could not bind contiguously on the oligodeoxynucleotides). Oligodeoxyribonucleotides 83-103 replication protein Escherichia coli 13-16 1658335-3 1991 Complexes of Rep protein were formed with short single-stranded and duplex hairpin oligodeoxynucleotides with lengths such that only a single Rep monomer could bind per oligodeoxynucleotide (i.e. 2 Rep monomers could not bind contiguously on the oligodeoxynucleotides). Oligodeoxyribonucleotides 246-267 replication protein Escherichia coli 13-16 1658335-5 1991 However, the binding of Rep monomers to single-stranded (ss) oligodeoxynucleotides, d(pN)n (12 less than or equal to n less than or equal to 20), induces the Rep monomers to oligomerize. Oligodeoxyribonucleotides 61-82 replication protein Escherichia coli 24-27 1658335-5 1991 However, the binding of Rep monomers to single-stranded (ss) oligodeoxynucleotides, d(pN)n (12 less than or equal to n less than or equal to 20), induces the Rep monomers to oligomerize. Oligodeoxyribonucleotides 61-82 replication protein Escherichia coli 158-161 1658335-6 1991 Upon treatment of the Rep-ss oligodeoxynucleotide complexes with the protein crosslinking reagent dimethyl-suberimidate (DMS) and subsequent removal of the DNA, crosslinked Rep dimers are observed, independent of oligodeoxynucleotide length (n less than or equal to 20). Oligodeoxyribonucleotides 29-49 replication protein Escherichia coli 22-25 1658335-6 1991 Upon treatment of the Rep-ss oligodeoxynucleotide complexes with the protein crosslinking reagent dimethyl-suberimidate (DMS) and subsequent removal of the DNA, crosslinked Rep dimers are observed, independent of oligodeoxynucleotide length (n less than or equal to 20). Oligodeoxyribonucleotides 29-49 replication protein Escherichia coli 173-176 1658335-7 1991 Furthermore, short duplex oligodeoxynucleotides also induce the Rep monomers to dimerize.
