We have characterized the Ca2+ binding properties of protein disulfide isomerase (PDI). It binds 19 mol Ca2+/mol protein with low affinity, which is reduced by increasing the ionic strength. Ca2+ induced conformational changes detected by UV difference spectroscopy. These Ca2+ binding properties resemble those of a sea urchin egg 58 kDa protein.© 1994 Academic Press, Inc.
