A Study of the Pyrimidine Biosynthesis Pathway and its Regulation in Two Distinct Organisms: Methanococcus jannaschii and Pseudomonas aeruginosa
Methanococcus jannaschii is a thermophilic methane producing archaebacterium. In this organism genes encoding the aspartate transcarbamoylase (ATCase) catalytic (PyrB) and regulatory (PyrI) polypeptides were found. Unlike Escherichia coli where the above genes are expressed from a biscistronic …

Direct Analysis of Intact Proteins From Microorganisms Using Top Down Mass Spectrometry
… down proteomics platform to study proteins from Methanococcus jannaschii and Saccharomyces cerevisiae. From the whole cell lysate of yeast, ∼120 ion species were successfully identified with 100% sequence coverage, and we also detected several post-translational modifications, including …

Exploration of Microbial Genomic Sequences via Comparative Analysis
… than GenMark. (2) The complete genome of Methanococcus jannaschii, combined with sequence data from its mesophilic relatives, is an excellent resource for the study of thermostability. 115 complete and partial protein sequences from the mesophilic relatives were aligned to M. jannaschii …

Investigation of regulatory and functional diversity in an enzyme superfamily
… synthase (IPMS) enzymes were analyzed. IPMS from Methanococcus jannaschii (MjIPMS) was investigated, and compared with the well characterized IPMS from Mycobacterium tuberculosis (MtIPMS). Isotope effects revealed the conservation of the mechanism of regulation in these different versions of IPMS …

Gene Expression in Archaea: Studies of Transcriptional Promoters, Messenger RNA Processing, and Five Prime Untranslated Regions in Methanocaldococcus Jannashchii
… 5'-untranslated regions in Methanocaldococcus (Methanococcus) jannaschii. The promoters in M. jannaschii are similar to eukaryotic RNA polymerase II promoters, with a TATA box and a transcription factor B recognition element being the core promoter elements. Protein-coding gene promoters bind …

Biochemical characterization of a novel iron-sulfur flavoprotein from Methanosarcina thermophila strain TM-1
… homologues from the CO2 reducing methanoarchaea Methanococcus jannaschii and Methanobacterium thermoautotrophicum. Extracts of H2-CO2-grown M. thermoautotrophicum cells were able to reduce Isf from M. thermophila using either H2 or CO as the reductant. Addition of ferredoxin A to the reaction …

Structural Characterisation of the Mammalian SRP Receptor
… structure of the homologous translocon from Methanococcus jannaschii suggests that SRβΔTM-apo/GDP blocks the translocation pore. Based on the molecular structure of the SRXHis:βΔTM-GTP SRX belongs to the SNARE-like superfamily with the common fold of the longin domains (LDs). The common …
