Hi Mark,

These are just the structure files which must be submitted to the RCSB protein database  before actual publication of the respective manuscripts. The 375 structure from the thermophilic methanogen Methanothermobacter thermautotrophicus is for an epimerase that converts UDP-sugars and is similar to the mru 1413 paper already approved and published. The 528 enzyme is also from the same methanogen and similar to another bacterial UDP-sugar processing enzyme. The epimerases (375) and the Mth528 enzyme are, as it turns out, highly similar to the bacterial and human ones, so not good targets for inhibitors. The Marsden fund supported the structure determinations. If you could approve these then that would be great, thanks (in advance).
