(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2009)Background Cyanobacteria often produce several different oligopeptides, with unknown biological functions, by nonribosomal peptide synthetases (NRPS). Although some cyanobacterial NRPS gene cluster types ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2011)Background Methane oxidizing prokaryotes in marine sediments are believed to function as a methane filter reducing the oceanic contribution to the global methane emission. In the anoxic parts of the sediments, ...

-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2009)Background: Large multigene sequence alignments have over recent years been increasingly employed for phylogenomic reconstruction of the eukaryote tree of life. Such supermatrices of sequence data are preferred over single ...
-
