... GPI-anchorless soluble version of the mutant protein. The K cat ⁄ K m value of the mutant TNSALP was less than one-tenth of the K cat ⁄ K m value of the soluble form of the wild-type enzyme, indicating ... defective mineralization of hard tis- sues. A replacement of valine with alanine at position 406, located in the crown domain of TNSALP, was reported in a perinatal fo...
