Aminopeptidase A Protein, Human (sf9, His)

Aminopeptidase A protein has calcium-regulating activity and plays a key role in central hypertension by preferentially cleaving N-terminal acidic residues, including angiotensin II. The specificity of this enzyme highlights its involvement in the regulation of blood pressure-related peptides, suggesting potential implications for the physiological mechanisms of hypertension. Aminopeptidase A Protein, Human (sf9, His) is the recombinant human-derived Aminopeptidase A protein, expressed by Sf9 insect cells , with N-His labeled tag. The total length of Aminopeptidase A Protein, Human (sf9, His) is 917 a.a., with molecular weight of ~115.5 kDa.

The Aminopeptidase A protein serves a pivotal role in the regulation of central hypertension, demonstrating a calcium-modulated preference for cleaving N-terminal acidic residues from peptides, including angiotensin II. This enzymatic activity highlights its involvement in the modulation of peptides associated with blood pressure regulation, suggesting a potential impact on the physiological mechanisms underlying hypertension. The calcium-dependent specificity of Aminopeptidase A underscores its intricate regulatory role in the processing of bioactive peptides, emphasizing its significance in cardiovascular function and potential relevance in the context of hypertensive conditions.

Measured by its ability to cleave the fluorogenic peptide substrate, Glu-7-amido-4-methyl coumarin (Glu-AMC) and the specific activity is >2000 pmol/min/μg.
