Need help, with this Bio - chemistry problem. Please, detail explanation...
Figure 2 (a) presents the results of lanmodulin in the absence and presence of the lanthanide ion, using the circular dichroism technique. Explain the conformational changes observed in lanmodulin when it is titrated with the lanthanide ion.
Figure 2 (b) presents titrations that were performed on lanmodulin with different metal ions from the lanthanide family, and also included the Ca2+ ion as part of the study. Explain the difference that was observed when comparing the results obtained with the lanthanides versus the Ca2+ ion.
