Phosphoglycolate phosphatase in human erythrocytes.
Human erythrocytes were found to contain an enzyme capable of dephosphorylating phosphoglycolate. The rates of hydrolysis of 14 other metabolites by the enzyme preparation were less than 6% of the rate with phosphoglycolate. The pH optimum is in the range of 6 to 7 and the Km for phosphoglycolate is 0.76 mM. The molecular weight appears to be about 79,000. Such an activity has previously been reported only for plant cells.
