Abstract
The present investigation was undertaken to clarify the effect of mucin, mucopolysaccharide and sugar components in mucin on the activity of amino acid activating enzyme, which was measured in the system containing tris buffer, MgCl2, ATP, P32-pyrophosphate, NaF and amino acids. The activity of amino acid activating enzyme was considerably increased by mucin, mucopolysaccharide and hexosamine, but not by hexose and hexuronic acid.
