Highly divergent genes for methanopterin-linked C1 transfer reactions in Lake Washington, assessed via metagenomic analysis and mRNA detection.

ABSTRACT: The origins and the evolutionary history of tetrahydromethanopterin-linked C1 transfer reactions that are part of two environmentally important biotransformations, methylotrophy and methanogenesis, are still not well understood. In previous studies, we have expanded the known phylogenetic diversity of these reactions by identifying genes highly diverging from the ones associated with cultivated Proteobacteria, Planctomycetes, or Archaea (M. G. Kalyuzhnaya, M. E. Lidstrom, and L. Chistoserdova, Microb. Ecol. 48:463-472, 2004; M. G. Kalyuzhnaya, O. Nercessian, M. E. Lidstrom, and L. Chistoserdova, Environ. Microbiol. 7:1269-1274, 2005). Here we used a metagenomic approach to demonstrate that these divergent genes are present with high abundance in the microbial community inhabiting Lake Wash
