Yields, molecular masses (SDS-PAGE) and the kinetic classification of purified cgAUS samples. 6 kg frozen petal material was used as starting material

Sample	Amount (mg)	M (kDa) (reducing SDS-PAGE)	M (kDa) (non-reducing SDS-PAGE)	Latent/active
1	2.45	37; 38	36; 37; 38	Active
2	0.56	37; 38	36; 37; 38	Active
3	0.37	37; 38	36; 37; 38	Active
4	1.25	37; 38	36; 37; 38	Active
5	0.87	59	65, 61, 54	Latent
6	0.25	38; 19	65, 54	Latent
7	0.12	37; 19	65, 54	Latent

Molecular masses were determined by reducing and non-reducing SDS-PAGE. Satellite bands exhibiting a shift to lower masses are found due to incomplete denaturation and/or incomplete reduction of the applied samples
