Finally, the opposing possibility explaining the existence of I. It might be advantageous in hyperthermophiles to maintain multiple copies of chromosomes per cell due to a probable need of a reserve supply of intact chromosome to compensate for the greater chance of DNA double strand breaks at high temperature [ 5152 ]. NiFe hydrogenase and sulfur reductase. Bernander R: Chromosome replication, nucleoid segregation and cell division in archaea. Trends Microbiol 65— For the mesophiles, the acidic peak is much larger than the basic peak, while the reverse is the case for hyperthermophiles. Red, blue and pink colours indicate the transmembrane, outside and inside regions of the protein respectively. Figure 6.

    Future experimental and comparative genomic analyses will be required to determine the evolutionary history and the function of these unrepresented operons and their encoded proteins. Correlation values between the pure and co-cultures calculated independently for each organism, i. Considering each operon as a gene set, we used the GSEA [24] to find operons differentially expressed between the two culturing conditions, I.

The four proteins predicted to form the complex small and large hydrogenase subunits, a 4Fe-4S ferredoxin, and a transmembrane membrane protein are encoded by genes that appear to be part of a single transcriptional unit Iho— ; all constituents were detected though the transmembrane protein was identified at very low levels, probably due the aforementioned tryptic incompatibility.

    The gene is part of an operon that encodes two hypothetical proteins Iho and with no known homologs, which were also expressed at similar levels to UspA.

    The first possibility is that the detected I. In an attempt to distinguish between these alternatives we compared the relative abundance of the detected proteins between the N.

    Another membrane complex that so far has not been associated with any cellular function is the outer membrane pore, assembled by the oligomerization of Iho [20].

    These data perhaps converge to a conclusion that N. Nanoarchaeum cannot synthesize most nucleotides, amino acids, lipids, and cofactors.

    1. Vogor:

      The general protocol for whole-cell shotgun proteomics is known to be superior for soluble proteins relative to membrane proteins, and thus translated into a lower fraction of identified transmembrane proteins as compared to total proteins
