| Description | Plant seed storage proteins, whose principal function appears to be the major nitrogen source for the developing plant, can be classified, on the basis oftheir structure, into different families. 11-S are non-glycosylated proteins which form hexameric structures [, ]. Each of the subunits in the hexamer isitself composed of an acidic and a basic chain derived from a single precursor and linked by a disulphide bond. This structure is shown in the followingrepresentation. +-------------------------+ | |xxxxxxxxxxxCxxxxxxxxxxxxxxxxxxxxxxNGxCxxxxxxxxxxxxxxxxxxxxxxx |------Acidic-subunit-------------||-----Basic-subunit------||-----------------About-480-to-500-residues-----------------| 'C': conserved cysteine involved in a disulphide bond.Members of the 11-S family include pea and broad bean legumins, oil seed rapecruciferin, rice glutelins, cotton beta-globulins, soybean glycinins, pumpkin 11-S globulin, oat globulin, sunflower helianthinin G3, etc.This family represents the precursor protein which is cleaved into the two chains. These proteins contain two β-barrel domains.This family is a member of the 'cupin' superfamily on the basis of their conserved barrel domain ('cupa' is the Latin termfor a small barrel). The signature pattern for this family includes the conserved cleavage site between the acidic and basic subunits (Asn-Gly) and a proximal cysteine residue which is involved in the inter-chain disulphide bond. |
