My final Structure of Christmas may look like an unremarkable enzyme, but it heralded the arrival of a game-changing method in structural biology.
My penultimate structure of Christmas is actually two molecular partners, which work together to make muscle move.
Once a parasite makes it past our outer defences, it encounters some seriously sophisticated weaponry. One of these is the ever-shifting antibody, my 7th structure of Christmas.
My 6th structure of Christmas is out to kill human gut cells, with help from a human protein. But has it simply shown up (drunk) at the wrong party?
Viruses live in a twilight zone, somewhere between life and its ingredients. My fifth structure of Christmas emerges from that zone to wreak havoc on cattle: the foot-and-mouth-disease virus.
The second structure of Christmas is the membrane protein opsin, which allows us to perceive light.
If there is one protein we can say we know inside and out, it is the humble lysozyme, which we carry in our tears. This is my first Structure of Christmas for 2016.
