## Abstract Oneβdimensional and twoβdimensional SDSβPAGE and Hydrophobic Cluster Analysis (HCA) were used for investigating the course of limited tryptic hydrolysis of faba bean legumin. SDSβPAGE revealed the formation of an βunequalβ subunit pattern, characterized by 30 and 50 kDa subunits, which
Legumin, the main storage protein of Viria faba seeds. consists of the two different subunit types A and B. Each subunit is composed of two polypeptide chains, one acidic (2) and one basic (p) linked by disulphide bridges. In each subunit type specific a-P-pairs occur. in type A 3-as well as 8-poly
Changes of the surfxe tension at a planar interface and of the emulsifying properties of tryptically digested legumin from faba beans (enzyme/substrate ratio = 1/40) were studied in terms of time of hydrolysis (0-48 h). Simultaneously, molecular changes of legumin were studied by determination of li
