  title={Carbonic Anhydrase IV from Human Lung},
  author={Xin Liang Zhu and William S. Slyf and Edward A. Doisy},
We have purified carbonic anhydrase (CA) IV from human lung membranes to apparent homogeneity in a form which is catalytically active and stable to storage. It has an apparent molecular mass of 35 kDa, is insensitive to endoglycosidases, and seems to contain no Nlinked or O-linked oligosaccharide chains. Reduction of disulfide linkages led to altered migration on sodium dodecyl sulfate-polyacrylamide gel electrophoresis and loss of catalytic activity. CA IV resembles CA II in being a “high… CONTINUE READING
