Product Information
Name:L-Alanine 4-nitroanilide hydrochloride
Synonyms:
- L-Ala-pNA·HCl
Brand:Biosynth
Description:L-alanine 4-nitroanilide hydrochloride (H-Ala-pNAHCl) functions as a substrate for L-alanine aminopeptidase, an enzyme found in bacterial cell walls that catalyzes the cleavage of L-alanine from peptides. Notably, significant activity of L-alanine aminopeptidase is specific to gram-negative microbes. Thus, the utilization of H-Ala-pNAHCl can provide evidence for distinguishing between gram-positive and gram-negative organisms. When acted upon by L-alanine aminopeptide, it undergoes cleavage into L-alanine and 4-nitroanine, with the latter compound causing bacterial suspensions to exhibit a yellow coloration.
