The picture shows the research submersible Alvin one year after the first exploration voyage to a hydrothermal spring (photo NOAA , 1978). The Alvin also hid the Archaeon M. jannaschi from the chimney base of a "white smoker " on the sea floor ( East Pacific Ridge , 20 ° 50'N, 109 ° 06'W, 2600 meters depth).

Methanocaldococcus jannaschii (formerly Methanococcus jannaschii ) is taxonomically a type of prokaryotic microorganism . As a methane generator, M. jannaschii belongsto the domain of the living beings Archaea .

M. jannaschii was isolated from a hydrothermal spring with a submarine from the Woods Hole Oceanographic Institution , is thermophilic and forms methane . It was the first archaeon to have its entire genome sequenced . According to Craig Venter , who led this sequencing project, the unique features of the genome provided strong evidence that there are three domains of living things.

Properties and metabolism

Methanocaldococcus jannaschii is a thermophilic, methanogenic organism, which means that methanogenesis produces methane as a by-product of metabolism. The archaeon can only grow with carbon dioxide and hydrogen as primary energy sources; this is in contrast to many other "methanococci" (such as Methanococcus maripalidus ), which can also use formate as the primary energy source. The genome includes many hydrogenases , such as a 5,10-methenyltetrahydromethanopterin hydrogenase, a ferredoxin hydrogenase (eha) and a coenzyme F420 hydrogenase.

M. jannaschii has a large number of inteins ; 19 intenins were discovered in a proteomics study.

Many novel metabolic pathways were developed in M. jannaschii , including the synthetic pathways for methanogenic cofactors, riboflavin, and polyamines (e.g.). In addition, an archaea-specific DNA polymerase family was investigated. Information on single-pass transmembrane proteins from M. jannaschii has been compiled in the Membranome database (e.g.).

Systematics

In 2002 a publication was published in which the domain Archaea is treated (book volume). Among other things, the Phylum Euryarchaeota (book chapter) and the new class Methanococci anchored in it (book section) are described there. The section on the new methanococci class with the new taxa and regroupings it contains, including the new species name Methanocaldococcus jannaschii, has been confirmed by the International Association of Microbiological Societies ( IUMS ).
