Prediction of functions for two LEA proteins from mung bean.
LEA (late embryogenesis abundant) proteins are associated with tolerance to water stress resulting from desiccation and cold shock. Although various functions have been proposed to LEA proteins, their precise role is not fully defined. In silico analysis of the amino acid sequence of two LEA proteins (early methionine-labeled Vigna, EMV) from the tropical legume crop, Vigna radiata identified a 20 residues motif 'GGQTRKQQLGSEGYHEMGRK' characteristic to group 1 LEA proteins. Structural analyses hypothesize these proteins to function like DNA/RNA binding proteins in protecting macromolecules/ membrane stabilization at the time of dehydration process.
