RT Journal Article SR Electronic T1 Myoglobin in Primary Muscular Disease: I. Duchenne Muscular Dystrophy: and: II. Muscular Dystrophy of Distal Type JF Journal of Medical Genetics JO J Med Genet FD BMJ Publishing Group Ltd SP 309 OP 322 DO 10.1136/jmg.10.4.309 VO 10 IS 4 A1 Romero-Herrera, A. E. A1 Lehmann, H.

YR 1973 UL http://jmg.bmj.com/content/10/4/309.abstract AB Skeletal myoglobin from two cases of muscular dystrophy, one of Duchenne muscular dystrophy, and one of muscular dystrophy of distal type, have been examined and no differences from normal human myoglobin were found. The opportunity has been taken to discuss the nature of minor fractions of myoglobin-like material which are found when human skeletal myoglobin is isolated. Those which have been observed in the present study have been artefacts and it was possible to demonstrate that they were due to deamidation of certain glutamine and asparagine residues.
