Fig. 4From: A new family of uncultivated bacteria involved in methanogenesis from the ubiquitous osmolyte glycine betaine in coastal saltmarsh sedimentsPhylogenetic analysis of the functional gene marker glycine betaine (GBT) reductase (GrdH) of Canditatus ‘Betaina sedimentti’, compared to glycine reductase (GrdB) and sarcosine reductase (GrdF). Boostrap values greater than 50% are shown. The scale bar represents substitutions per amino acid. grdHI encodes for the selenoprotein betaine reductase; trxB and trxA encode for thioredoxin reductase and thioredoxin, respectively; opuD encodes for a BCCT-type GBT transporter; selA encodes for selenocysteine synthase; tetR, lysR and gntR encode for transcriptional regulatorsBack to article page
