The invention discloses aminopeptidase and a coding gene thereof, the aminopeptidase is an aminopeptidase sequence derived from Bacillus licheniformis YN, and the aminopeptidase belongs to the field of food enzyme engineering. The method comprises the following steps: purifying bacillus licheniformis YN fermentation liquor to obtain electrophoretic pure aminopeptidase, and determining that the aminopeptidase has a good effect on substrates such as leucine-p-nitroaniline, methionine-4-nitroaniline, L-proline-4-nitroaniline, L-lysine-4-nitroaniline, L-arginine-4-nitroaniline, L-valine-4-nitroaniline, L-amidine-4-nitroaniline, L-amidine-4-nitroaniline, L-amidine-4-nitroaniline, L-amidine-4-nitroaniline, L-amidine-4-nitroaniline, L-amidine-4-nitroaniline, L-amidine-4-nitroaniline, L-amidine-4-nitroaniline, L-amidine-4-nitroaniline, L-amidine-4-nitroaniline, l-phenylalanine-4-nitroaniline has catalytic activity, the substrates with the highest catalytic activity are proline, leucine and lysine ...
