Genomes: Methanococcus jannaschii and the golden fleece
The total genome sequence of the archaeon Methanococcus jannaschii completes the trilogy of genomes for the three domains of life-Archaea, Bacteria and Eucarya. It will have far-reaching consequences for evolutionary studies and for the way in which experimental biology is performed.
متن کاملHelical tubes of FtsZ from Methanococcus jannaschii.
Bacterial cell division depends on the formation of a cytokinetic ring structure, the Z-ring. The bacterial tubulin homologue FtsZ is required for Z-ring formation. FtsZ assembles into various polymeric forms in vitro, indicating a structural role in the septum of bacteria. We have used recombinant FtsZ1 protein from M. jannaschii to produce helical tubes and sheets with high yield using the GT...
متن کاملProtein-coding gene promoters in Methanocaldococcus (Methanococcus) jannaschii
Although Methanocaldococcus (Methanococcus) jannaschii was the first archaeon to have its genome sequenced, little is known about the promoters of its protein-coding genes. To expand our knowledge, we have experimentally identified 131 promoters for 107 protein-coding genes in this genome by mapping their transcription start sites. Compared to previously identified promoters, more than half of ...
متن کاملJason and the Golden Fleece of Agent-Oriented Programming
This chapter describes Jason, an interpreter written in Java for an extended version of AgentSpeak, a logic-based agent-oriented programming language that is suitable for the implementation of reactive planning systems according to the BDI architecture. We describe both the language and the various features and tools available in the platform.
متن کاملNew class of IMP cyclohydrolases in Methanococcus jannaschii.
The enzyme responsible for observed IMP cyclohydrolase activity in Methanococcus jannaschii was purified and sequenced: its genetic locus was found to correspond to gene MJ0626. The MJ0626 gene was cloned, and its protein product was expressed in Escherichia coli and shown to catalyze the cyclization of 5-formylamidoimidazole-4-carboxamide ribonucleotide to IMP. The enzyme has no sequence simil...
