Thank you for this novel study! The evolution of such proteins (now found in antarctica environmentys and clathrates) raises fascinating question about the evolution of this capability. From the tree you showed are there hypotheses about how deeply branching this capability might be; when and in what environments it might have evolved? Thank you – question posed by Barbara Sherwood Lollar (barbara.sherwoodlollar@utoronto.ca)

What are the principle kinds of microbes that posess clathrate-binding proteins? Are these bacteria consuming or producing the clathrate hydrocarbons?

Do you know how the CPBs actually help the bacteria survive/thrive in the clathrates? For example, do the bacteria feed on methane and the CPBs help in making the methane more accessible?

Dear Abigail, what a clear and interesting presentation! I was wondering, which microorganisms do you typically find in these clathrades? Do they utilize the gas inside, and to which taxa do these microorganisms belong?
