Comparative analysis of the active sites and targeting signal of plant catalases.

	Total	Containing catalase active sites		Containing oxidase active sites		Containing peroxisomal targeting signal (PTM)
		Number	Proportion (%)	Number	Proportion (%)	Number	Proportion
From betalain-forming plants	10	10	100	10	100	9	90
Other plants	60	59	98.3	60	100	10	16.7

The AcCATPO sequence obtained was used as a query selecting results with total score >800 (E = 0, except partial sequences).
