Characterization of Activity of a Potential Food-Grade Leucine Aminopeptidase from Kiwifruit

Table 1

Aminopeptidase activity in different parts of kiwifruit^a.

Type of tissue	Total activity (units/g fresh weight)	Specific activity (units/mg soluble protein)
Outer pericarp	0.38±0.15	0.37±0.10
Inner pericarp	0.64±0.19	0.52±0.07
Core	2.91±0.68	3.68±0.96
Seed	60.15±7.99	5.78±0.48

^aAminopeptidase (AP) activity was determined in extracts of each tissue from three different fruits of A. deliciosa. Mean values ± standard errors are presented.
