Abstract
Serum and urinary muramidase assays are of greatest value in diagnosing myelomonocytic and chronic myelocytic leukemia and in evaluating renal tubular damage. Like all known enzymes, muramidase is a protein. The assay of this enzyme is based on its ability to hydrolyze the cell wall of Micrococcus lysodeikticus, the substrate in most turbidimetric assay methods and in the agar-plate method of Osserman.
