Hi Mark

We would like to publish this short manuscript on Mru1413. This enzyme was selected quite a while ago as possibly being involved in the production of the archaeal sugar in the glycan backbone of pseudomurein. It shares about 50% amino acid sequence identity with bacterial and human enzymes. When it was crystallized we found it actually had a well-known bacterial sugar in the active site which looked like it was binding very tightly (we think this must have picked up from E. coli when we expressed it, as this is very unlikely to be an archaeal sugar). The work on this protein began under the PGGRC, but much of the work was done under the Marsden. At the moment we do not know if it is involved, and are unlikely to be able to figure it out, so the paper pretty-much stands as it is.
