- Woodson J, Reynolds A, Escalante Semerena J. ABC transporter for corrinoids in Halobacterium sp. strain NRC-1. J Bacteriol. 2005;187:5901-9 pubmed..Halobacterium synthesized cobalamin in a chemically defined medium lacking corrinoid precursors. To the best of our knowledge, this is the first genetic analysis of an archaeal corrinoid transport system...
- Zayas C, Woodson J, Escalante Semerena J. The cobZ gene of Methanosarcina mazei Go1 encodes the nonorthologous replacement of the alpha-ribazole-5'-phosphate phosphatase (CobC) enzyme of Salmonella enterica. J Bacteriol. 2006;188:2740-3 pubmed..strain NRC-1. A strain of the latter carrying an in-frame deletion of ORF Vng1577 was not a cobalamin auxotroph, suggesting that either there is redundancy of this function in Halobacterium or the gene was misannotated...
- Kaur A, Pan M, Meislin M, Facciotti M, El Gewely R, Baliga N. A systems view of haloarchaeal strategies to withstand stress from transition metals. Genome Res. 2006;16:841-54 pubmed
- Woodson J, Zayas C, Escalante Semerena J. A new pathway for salvaging the coenzyme B12 precursor cobinamide in archaea requires cobinamide-phosphate synthase (CbiB) enzyme activity. J Bacteriol. 2003;185:7193-201 pubmed..The existence of an adenosylcobinamide amidohydrolase enzyme would explain the lack of an adenosylcobinamide kinase in archaea...
