OK. Looks quite interesting. It could help also in the problem of the
origin of life, although here it is the RNA which would need to be
“Turing complete” (in that loose sense of belonging to a possible
universal machinery).
In the origin of life it must be the system, including some aspects of
the environment that constitute Turing complete or near Turing complete
machinery. Nick Lane is an advocate of metabolism first has written a
nice popular book on the origin of life "The Vital Question" in which
the ATP cycle precedes RNA.

In principle, one protein + one DNA strands (that the protein should
be able to elongated if needed) can be a genuine Turing universal
machine. They always need some elongate-able tape...
