Proteases catalyze the hydrolysis of peptide bonds in proteins. They are widely distributed in nature, nearly in all plants, animals and microorganisms. Plant latex is a rich source of proteases. Latex production is unique property of Euphorbian plant, which could be a potential source of proteolytic enzymes. The highest proteolytic activity was observed in the latex of Pedilanthus tithymaloides Linn., which is followed by lattices of Euphorbia tirucalli Linn., Euphorbia nivulia Buch.-Ham., and Euphorbia nerifolia Linn. Therefore, P. tithymaloides, E. tirucalli, E. nivulia, and E. nerifolia lattices were selected as potential sources of proteases. These proteases were effectively used to remove hair from goat skin indicating its potential in leather processing industry. These proteolytic enzymes showed potential environmental waste management applications such as degradation of chicken feather waste. Additionally, the crude enzymes of the selected plants exhibited potent gelatinolytic activity almost correlated to release of silver from waste X–ray film. They also showed remarkable destaining property, indicating their importance in detergent industry. These enzymes have remarkable silk degumming property demonstrating their use in textile industries.
