Aldolase and phosphoglycerate kinase activity were markedly reduced in muscle from two mouse mutants, 129 J-dy and A2G-adr, with abnormal muscle development. The pentose-phosphate shunt enzymes, glucose-6-phosphate dehydrogenase and 6-phosphogluconate dehydrogenase, were both greatly increased in the gastrocnemius of 129 J-dy mice, but only the former was(More)
1. The molecular weight of arginine kinase from lobster muscle has been determined by three procedures: ultracentrifuge analysis, gel filtration and density-gradient centrifugation. 2. The three methods give similar results and the best estimate of the molecular weight is 37000. 3. The enzyme does not readily show association-dissociation phenomena. 4. The(More)
This paper compares the results of a survey of plasma creatine kinase (CK) activity measured in fetuses at-risk for Duchenne muscular dystrophy (DMD) with a reliable control series. Only pure fetal blood samples obtained by fetoscopy at between 17-24 weeks gestational age were used. Of the at-risk group 19 male pregnancies, mostly at low risk for DMD,(More)
