Members of the H+, Na+-translocating Pyrophosphatase (M+-PPase) Family (TC# 3.A.10) are found in the vacuolar (tonoplast) membranes of higher plants, algae, and protozoa, and in both bacteria and archaea. (wikipedia.org)
Full-length members of the H+-PPase family have been sequenced from numerous bacteria, archaea and eukaryotes. (wikipedia.org)
Those from respiratory and photosynthetic bacteria as well as archaea are less dependent upon K+. (wikipedia.org)
NADH-dependent reduced ferredoxin:NADP oxidoreductase (NfnAB) is found in the cytoplasm of various anaerobic bacteria and archaea. (nih.gov)
Moreover, subsequent work by Woese indicated that the archaea domain had an ancestor in common with eukaryotes which was not shared by bacteria. (nih.gov)
Consequently, as each new hyperthermophilic species was isolated, virtually all were found to be members of the archaea. (nih.gov)
The ecology and taxonomy of the hyperthermophilic archaea are discussed in the first chapter by John Baross and James Holden. (nih.gov)
The fact that most hyperthermophilic organisms are archaea rather than bacteria raises several interesting questions regarding the nature of their biochemical pathways and the enzymes and proteins involved. (nih.gov)
The subsequent two chapters by Robert Maier and by Arnulf Kletzin and me discuss these issues with reference to the respiratory chains of sulfur-respiring organisms and to the fermentative pathways of the hyperthermophilic archaea, respectively. (nih.gov)
The ability to metabolize complex carbohydrates and proteinaceous materials is virtually a characteristic of the hyperthermophiles, including the majority of the archaea and T. maritima. (nih.gov)
Fermentative1
All H+-PPases require Mg2+, and those from plant vacuoles, acidocalcisomes of protozoa and fermentative bacteria require mM K+. (wikipedia.org)
Enzyme1
We also discuss the first struc- tural information to be obtained on both a hyperthermophilic protein (rubredoxin) and a hyperthermophilic enzyme (aldehyde ferredoxin oxidoreductase). (nih.gov)
Archaeoglobus2
In this study, a hyperthermophilic HAD-like phosphatase from Archaeoglobus fulgidus (AfPase) was cloned, expressed, and characterized. (springeropen.com)
A hyperthermophilic HAD-like phosphatase from Archaeoglobus fulgidus was characterized carefully, and the success of an in vitro synthetic enzymatic biosystem containing this phosphatase provided a promising approach for DHA production from maltodextrin. (springeropen.com)
Metabolism1
Hence, the main purpose of this review is to shed light on how bacteria fuels microalgal metabolism or vice versa during mutualistic interactions, building upon the phycosphere which is a hotspot for chemical exchange. (bvsalud.org)
Hydrogen1
Hyperthermophilic heat loving bacteria (Thermotogales) They produce hydrogen by fermenting sugars. (topsan.org)
