Has the effect of Ca2+ on demethylation been tested? If not, do you intend to test this?
No, we have not directly assayed the effect of calcium on demethylation (i.e we have not varied calcium concentrations and then measured effect). We could certainly do that. Interestingly, to the best of my knowledge, no one has examined what the effect of varying calcium concentrations might be on methanotrophic activity/gene expression. Something to consider...thanks! What we are doing at the moment to perhaps address this issue is purify the two forms of methanol dehydrogenase, and then with varying amounts of methanobactin, determine rates and extent of methylmercury degradation.

Hi Jeremy, very interesting work. I wondered if you have any plans to do any Cu isotope analyses along these lines? If not, but you might be interested, please do get in touch offline. All the best, Susan Little
Hi Susan, Thanks for the positive comments. In short, no, we've not done any copper isotope analyses. But it's an interesting thought. I will ping you off-line.
