Speaking as a former macromolecular crystallographer, I don't think you
should be too surprised. There are two types of crystallographers: those who
use crystallography as a tool to study molecules they are interested in, and
those who use any available molecule, hopefully of some interest to
somebody, to develop crystallographic techniques. Sounds like your
acquaintance is one of the former, and Qinghong Zeng is one of the latter.
Zeng might be from China where there could very well be a shortage of
suitable proteins. It actually seems to me to be a very good way to scare
up an interesting problem.

I imagine Zeng would answer yes.
