Metallothioneins: Protein structure prediction and sequence analyses in Cajanus cajan

Protein structure prediction and sequence analyses in Cajanus cajan

Abstract

Metallothioneins are a special group of small proteins capable of detoxifying non-essential metal ions present in excess within a plant cell. Metallothioneins are cysteine-rich diverse classes of heavy metal binding protein molecules which are essential for plant growth. These proteins are present in all taxa, except eubacteria. In this study, from available genomic resources metallothionein of pigeonpea was identified, structure of metallothionein was predicted and validated. We have presented a step-wise methodology to model a given protein and later on to validate the produced structures based on Ramchandran plot analysis.
