comment Is there any evolutionary advantage of selection of L-amino acid over D-amino acid?
@ChrisStronks And the mirror structure result would almost certainly be the same for any protein. A protein is the same as any other molecule in that if you flip all of the chiral centers you end up with its mirror image.

comment Is there any evolutionary advantage of selection of L-amino acid over D-amino acid?
@ChrisStronks At least for enzyme activity, I think that the invariance of L- and D- follows from the fact that electromagnetic interactions don't change for a parity transformation (reflection is a type of parity transformation). So it would probably be the same for any enzyme.

comment Mass spectrometry versus western blotting for validation
Ohhh, reviewers and their blots. I think that I have heard similar stories several dozen times now. Have you done replicates of the blots?

comment Mass spectrometry versus western blotting for validation
Trying to answer any question other than "is this protein actually present in my sample" with a Western seems like a fool's errand. I think that it's completely reasonable to expect a large variability between your two methods.

comment Hot water and bacteria
@DavidRicherby I changed the wording a little to reflect your comments, but I am curious about what you said. Do you have a reference?

comment What is the biggest facultative anaerobic metazoan known to science?
The answer to your question is going to be some plant or fungus. You might want to stick the word "metazoan" somewhere in your question.
