If I had been more atop things, I would have written this just under a week ago, on the nineteenth anniversary of my starting to write in this space.  That's a milestone, and actually writing something is the way to try to push back towards some regular frequency in posting here.  But the real reason for the title is something I've mused on a small bit for many of those years: can we shave one amino acid out of the proteome?
