L-Alanine 4-nitroanilide hydrochloride Size:50 g which subsequently reduce the colorlessH Ala pNAHCl is a substrate for L alanine aminopeptidase, which is an enzyme that is localized in bacterial cell walls responsible for the cleavage of L alanine from various peptides. Significant L alanine aminopeptidase activity is specific to gram negative microbes. Therefore, H Ala pNAHCl can be used in support of evidence that an organism is gram positive or gram negative. It is split by L alanine aminopeptide into L alanine and 4 nitroanine. The
