My pleasure. Btw, my previous literature search wasn't quite that exhaustive. I searched some more and found papers from 2010 and 2013 where scientists have finally worked out how the NylA and NylC enzymes evolved. By standard gene duplication and divergence, from chromosomally encoded bacterial proteins of two different types. I'll make a post on it later.
