Abstract:
A phylogenetic analysis was carried out of a total of 58 P-type ATPases encoded within the genomes of 20 archaea species. Members from six subfamilies were identified including: putative metal-, proton-, calcium-, sodium/potassium-, potassium-, and magnesium/nickel-transporting ATPases. Six novel putative proton-ATPases from archaea species growing under different temperature and pH conditions were shown to have shorter N- and C-termini than those of orthologous yeast or plant proton-ATPases. Moreover recent biochemical data are reviewed that report functional expression of putative archaea metal- or proton-ATPases in bacteria or yeast.

ATP Driven Pumps II: P-type Pumps
A typical P-type pump has three cytosolic domains: nucleotide-binding (N), phosphorylation (P), and activator (A) domains. These domains are connected to the membrane-spanning helices by short amino acid segments. ATP hydrolysis and covalent phosphoenzyme intermediate formation are crucial parts of the catalytic cycle. At the highly...
