Figure 4. Tolerance of P4H activity to salts.

Figure 4

P4H activity is shown in the absence and presence of increasing concentrations of sodium chloride (NaCl), sodium bromide (NaBr), sodium iodide (NaI), potassium fluoride (KF), potassium chloride (KCl), potassium bromide (KBr), and potassium iodide (KI). Reaction mixtures are described in the Materials and Methods section.
