Abstract
With oligonucleotides modelled after conserved regions within the protein-serine/threonine phosphatases (PPs) of the PP1/2A/2B superfamily, the gene for the archaeal protein phosphatase PP1-arch2 was identified, cloned, and sequenced from the methanogenic archaeon Methanosarcina thermophila TM-1. The DNA-derived amino acid sequence of PP1-arch2 exhibited a high degree of sequence identity, 27 to 31%, with members of the PP1/2A/2B superfamily such as PP1-arch1 from Sulfolobus solfataricus, PP1alpha from rats, PP2A from Saccharomyces cerevisiae, and PP2B from humans. The activity of the recombinant PP1-arch2 was sensitive to several naturally occurring microbial toxins known to potently inhibit eucaryal PP1 and PP2A, including microcystin-LR, okadaic acid, tautomycin, and calyculin A.Entities:
