we measured the excretion rates of six urinary enzymes that either originate from the proximal renal tubule , like alanine aminopeptidase ( ec 3.4.11.2 ) , alkaline phosphatase ( ec 3.1.3.1 ) , gamma-glutamyltransferase ( ec 2.3.2.2 ) , and n-acetyl-beta-d-glucosaminidase ( ec 3.2.1.30 ) , or that are typical low-molecular-mass proteins , like lysozyme ( ec 3.2.1.17 ) and pancreatic ribonuclease ( ec 3.1.27.5 ) .
