Biological Activity

Description

Aminopeptidase A, modulated by calcium, regulates central hypertension by preferentially cleaving N-terminal acidic residues from peptides, including angiotensin II. Aminopeptidase A Protein, Rat (sf9, His) is the recombinant rat-derived Aminopeptidase A protein, expressed by Sf9 insect cells , with N-His labeled tag.

Background

Aminopeptidase A, a key regulatory enzyme, exerts control over central hypertension by exhibiting a calcium-modulated specificity for cleaving N-terminal acidic residues from peptides, with notable significance in processing angiotensin II. Through this catalytic activity, Aminopeptidase A contributes to the intricate modulation of physiological processes related to blood pressure regulation, underscoring its pivotal role in central hypertension pathways.

Verified Bioactivity

Measured by its ability to cleave 200 μM substrate Glu-7-amido-4-methylcoumarin that incubate at 37 ℃ in kinetic mode for 5 minutes. The specific activity is 25877.184 pmol/min/µg.
