Abstract
Extracts containing UDP glucose dehydrogenase (EC 1.1.1.22) activity were prepared from rheumatoid and from normal human synovial cell lines using previously standardized techniques. Although no significant differences in the enzyme from the 2 sources were detected with respect to activity, substrate affinities, or responses to temperature and pH, these determinations demonstrated that the enzyme is very sensitive to alterations in these parameters. The ultimate activity of the enzyme in vivo will be dependent upon the extent of the increased temperature, acidity and altered glucose metabolism in the rheumatoid joint.
