The Lysozyme from <em>Asterias rubens</em>.

Lysozyme (mucopeptide N-acetylmuramylhydrolase) from Asterias rubens was obtained in a chromatographically and electrophoretically pure state by gel filtration and affinity chromatography. The quantitative amino acid composition, the molecular weight and the N-terminal sequence determined by a sequencer are reported. This new invertebrate enzyme presents important differences when compared to previously studied lysozymes. [ABSTRACT FROM AUTHOR]
