A phosphoserine-containing peptide was identified from tryptic digests from Sulfolobus solfataricus P1 by liquid chromatography-tandem mass spectrometry. Its amino acid sequence closely matched that bracketing Ser-309 in the predicted protein product of open reading frame sso0207, a putative phosphohexomutase, in the genome of S. solfataricus P2. Open reading frame sso0207 was cloned, and its protein product expressed in Escherichia coli. The recombinant protein proved capable of… CONTINUE READING
