We report here a new phosphoglycerate kinase variant discovered in a boy with severe hemolytic anemia but no evidence of neuromuscular disease or developmental delay. The biochemical properties of the variant enzyme (greatly increased k<jats:sub>m<\/jats:sub>ATP and k<jats:sub>m<\/jats:sub>3\u2010phosphoglycerate; normal pH optimum, electrophoretic mobility, and substrate specificity; resistance to heat inactivation) establish its uniqueness. Separation of light and dense red cells by centrifugation showed no greater loss of phosphoglycerate kinase activity in dense (\u201cold\u201d) variant cells than in normal cells. We postulate that the striking stability of the variant enzyme allows cells capable of protein synthesis to accumulate sufficient enzyme to limit neuromuscular sequelae.<\/jats:p>","DOI":"10.1002\/ajh.2830250207","type":"journal-article","created":{"date-parts":[[2007,2,21]],"date-time":"2007-02-21T11:09:32Z","timestamp":1172056172000},"page":"175-182","source":"Crossref","is-referenced-by-count":8,"title":["Phosphoglycerate kinase San Francisco: A new variant associated with hemolytic anemia but not with neuromuscular manifestations"],"prefix":"10.1002","volume":"25","author":[{"given":"M.
