Fig. 6From: The complete genome sequence of the methanogenic archaeon ISO4-H5 provides insights into the methylotrophic lifestyle of a ruminal representative of the Methanomassiliicoccales Analysis of pyrrolysine biosynthesis gene cluster in Methanomassiliicoccales. Gene organization of the pyrrolysine gene clusters for the six Methanomassiliicoccales genomes are displayed. The operon includes a pyrrolysine corresponding tRNA(CUA), pylT; pyrrolysine-tRNA ligase, pylS; methylornithine synthase, pylB; (2R,3R)-3-methylornithyl-N 6-lysine synthase, pylC; and pyrrolysine synthase, pylD. The strain names are given on the left-hand side of each scheme. Strain B10 has two clusters, (1) and (2), as indicated next to the strain nameBack to article page
