Hi Mark

We've updated this already-approved paper (see details) below which is now ready for submission (more than 2 years later, as we have been busy doing other things!). As mentioned in the ROI678. there is a structure already from a methanogen. It would be good to publish this for recognition for both the PGGRC and us...The differences between this one and the previous are a bit more discussion, and the intro has been changed to reflect new terminology that is being used for this complex set of pathways. Happy to chat about it or send more details.  Best wishes.

Ron
