We provide metagenomic insights into an iron mat at the L\u014d\u00b4ihi Seamount, Hawai\u00b4l, revealing novel genomic information of locally dominant <em>Zetaproteobacteria<\/em> lineages. These lineages were previously estimated to account for ~13% of all local <em>Zetaproteobacteria<\/em> based on 16S clone library data. Biogeochemically relevant genes include nitrite reductases, which were previously not identified in <em>Zetaproteobacteria<\/em>, sulfide:quinone oxidases, and ribulose-1,5-bisphosphate carboxylase (RuBisCo). Genes assumed to be involved in Fe(II) oxidation correlate in synteny and share 87% amino acid similarity with those previously identified in the related <em>Zetaproteobacterium<\/em> <em>Mariprofundus ferrooxydans<\/em> PV-1. Overall, <em>Zetaproteobacteria<\/em> genes appear to originate primarily from within the <em>Proteobacteria<\/em> and the Fe(II)-oxidizing <em>Leptospirillum<\/em> spp. and are predicted to facilitate adaptation to a deep-sea hydrothermal vent environment in addition to microaerophilic Fe(II) and H<sub>2<\/sub>S oxidation. This dataset represents the first metagenomic study of FeOB from an iron oxide mat at a deep-sea hydrothermal habitat.<\/p>\n","protected":false},"template":"","tags":[],"publication_type":[19],"_links":{"self":[{"href":"https:\/\/www.darkenergybiosphere.org\/wp-json\/wp\/v2\/publication\/7637"}],"collection":[{"href":"https:\/\/www.darkenergybiosphere.org\/wp-json\/wp\/v2\/publication"}],"about":[{"href":"https:\/\/www.darkenergybiosphere.org\/wp-json\/wp\/v2\/types\/publication"}],"wp:attachment":[{"href":"https:\/\/www.darkenergybiosphere.org\/wp-json\/wp\/v2\/media?parent=7637"}],"wp:term":[{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.darkenergybiosphere.org\/wp-json\/wp\/v2\/tags?post=7637"},{"taxonomy":"publication_type","embeddable":true,"href":"https:\/\/www.darkenergybiosphere.org\/wp-json\/wp\/v2\/publication_type?post=7637"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
