Biochem Prep 6:769.incubation at ambient temperature, the enzymes were removed by passing the reaction mixture through an Amicon spin column (10-kDa molecular weight cutoff; MWCO). The conversion of the reaction (60 ) was calculated by integrating the signals of starting material and product by 31P-NMR spectroscopy. To this solution, L-Leu-L-Ala(P) was added such that the final ratio of monomethylated/unmethylated dipeptide was 1:1.2. After lyophilization, the material was dissolved in 0.5 mL of a solution containing 6 mM -KG, 3 mM L-ascorbic acid, 0.2 mM (NH4)2Fe(SO4)2, and 40 M MBP-DhpJ reconstituted on ice in an anaerobic chamber with 1.ISRIB 2 equivalent of Fe(II). The reaction mixture was incubated for 5 h at room temperature. Then, approximately 100 L of Chelex 100 resin was added to the reaction tube to remove iron ions, and the solution was passed through an Amicon spin column (30 kDa MWCO). Before NMR analysis, 150 L of D2O was added into the sample. Based on integration of the signals of Fig. 4C, about 21 was side-product, about 37 L-Leu-Ala(POMe), about 37 L-Leu-Ala(P), and about 5 belonged to MAP. ACKNOWLEDGMENTS. We thank Susan A.
