High impact information on Pyrodictiaceae

  • Pyrodictium brockii is a hyperthermophilic archaebacterium with an optimal growth temperature of 105 degrees C. P. brockii is also a chemolithotroph, requiring H2 and CO2 for growth [1].
  • ATP synthesis at 100 degrees C by an ATPase purified from the hyperthermophilic archaeon Pyrodictium abyssi [2].
  • Molecular cloning and functional expression of a protein-serine/threonine phosphatase from the hyperthermophilic archaeon Pyrodictium abyssi TAG11 [3].
  • The hyperthermophilic archaebacterium Pyrodictium brockii grows optimally at 105 degrees C by a form of metabolism known as hydrogen-sulfur autotrophy, which is characterized by the oxidation of H2 by S0 to produce ATP and H2S [4].
  • Pyrodictium abyssi and Pyrodictium occultum ( Pyrodictiaceae) contained ribulose 1,5-bisphosphate carboxylase, which was active in boiling water [5].
 

Biological context of Pyrodictiaceae

  • An open reading frame coding for a putative protein-serine/threonine phosphatase was identified in the hyperthermophilic archaeon Pyrodictium abyssi TAG11 and named Py-PP1 [3].
  • The Pyrodictium initiator tRNA sequence predicted from the gene sequence contained all of the nucleotide residues A1, A37, U54, A57, U60, and U72, in addition to three G-C base pairs in the anticodon stem region, which are characteristic of archaeal initiator tRNAs [6].
