title: Identification and characterization of inorganic pyrophosphatase and PAP phosphatase from Thermococcus onnurineus NA1.
abstract: Two hypothetical genes were functionally verified to be a pyrophosphatase and a PAP phosphatase in Thermococcus onnurineus NA1. This is the first report of the pyrophosphatases and the PAP phosphatases being organized in the gene clusters of the sulfate activation system only in T. onnurineus NA1 and "Pyrococcus abyssi."
