Abstract
Seed storage proteins not just provide essential nutritional ingredients for growth of seedlings but also have their potential role in defense mechanisms of plants. Napin is a seed storage protein and belongs to 2S albumin family. Napin and napin-like protein have many biological defensive activities including antifungal, antimicrobial, trypsin inhibitor, and also act as antagonist of calmodulin. Napin protein possesses various isoforms with different biological activities. In this study, the protein sequence of napin from Momordica charantia was retrieved from GenPept database for characterization. A complete annotation of napin including its physicochemical properties was done. Three dimensional (3D) modeling and interactions of napin-like protein with other proteins were also predicted using various bioinformatics tools. A phylogram of napin-like protein from M. charantia with its homologs was also reconstructed to reveal its evolutionary relationships with napins and other 2S albumin proteins from various plants. The study has revealed the structural characterization, biological interactions, and evolutionary background which will play crucial role in exploring the medicinal and biological potentials of napin-like protein from M. charantia as well as worth of napin and napin-like protein has been disclosed.
