The structure of MP-4 from Mucuna pruriens at 2.22 Å resolution.

The structure of the MP-4 protein was previously determined at a resolution of 2.8 Å. Owing to the unavailability of gene-sequence information at the time, the side-chain assignment was carried out on the basis of a partial sequence available through Edman degradation, sequence homology to orthologs and electron density.

Comparative study of 7S globulin from Corylus avellana and Solanum lycopersicum revealed importance of salicylic acid and Cu-binding loop in modulating their function.

The plant seed proteins referred to as vicilins belong to a structurally common superfamily. While some of them are reported to exhibit superoxide dismutase activity, vicilins from other sources do not possess this activity. Vicilin from Corylus avellana (HZ.

Structure-guided identification of function: role of vicilin during oxidative stress.

Proteins belonging to cupin superfamily are known to have critical and diverse physiological functions. However, 7S globulins family, which is also a part of cupin superfamily, were undermined as only seed storage proteins. Structure determination of native protein - Vic_CAPAN from was carried out, and its physiological functions were explored after purifying the protein by ammonium sulfate precipitation followed by size exclusion chromatography.
