LAP (Leucine Aminopeptidase) Test
Leucine aminopeptidase (LAP) is an enzyme that is employed in a test for the presumptive identification of Streptococci. LAP is a peptidase that hydrolyzes peptide bonds near free amino groups. LAP is known as leucine aminopeptidase because it responds most efficiently with leucine. Leucine- β-naphthylamide is hydrolyzed to yield β-naphthylamine. …
