P-2 279-282 replication protein Escherichia coli 31-34 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].
