Comments(2)Acknowledging an earlier observation of orphan SelDDaniel Haft
(04 March 2008) J. Craig Venter Institute Just after publication of our manuscript, we came across the following reference: Zhang Y, Romero H, Salinas G, Gladyshev VN., Dynamic evolution of selenocysteine utilization in bacteria: a balance between selenoprotein loss and evolution of selenocysteine from redox active cysteine residues. Genome Biol. 2006;7(10):R94. Epub 2006 Oct 20. We launched our study from the observation that SelD proteins explained by neither selenocysteine nor selenouridine pathways might imply a third SelD-dependent trait. The orphan status of SelD in Enterococcus faecalis and Haloarcula marismortui and possibility of SelD-dependence for selenium-dependent molybdenum hydroxylases were raised previously by Zhang, et al., and should have been cited as background to this paper. We regret having been unaware of this earlier observation.
