Treatment with acid or alkaline solutions causes spectral changes which may be due to dissociation of the enzyme into subunits and removal of the heme group from the protein. The fractions of the protein structure present as \u03b1 helix, \u03b2 pleated sheet, and unordered structure have been estimated from the CD spectrum in the far-ultraviolet region. The CD spectra also indicate that the protein conformation does not change appreciably after cyanide binding. The epr spectroscopy of the native enzyme and its cyanide complex are reported. The spectral results are compared with catalase obtained from other mammalian and bacterial sources. <\/jats:p>","DOI":"10.1139\/o79-041","type":"journal-article","created":{"date-parts":[[2009,12,21]],"date-time":"2009-12-21T14:54:28Z","timestamp":1261407268000},"page":"321-329","source":"Crossref","is-referenced-by-count":12,"title":["Spectral studies of human erythrocyte catalase"],"prefix":"10.1139","volume":"57","author":[{"given":"Monica","family":"Palcic","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"H.
