Physico-chemical properties of identified proteome The hydrophobic nature of the identified proteins was calculated using the GRAVY (grand average hydropathy) tool and the score obtained ranges between − 1.6 and 1 (Additional file 2: Figure S1a). Nearly 88% of the proteins were hydrophilic (< 0) and the rest were hydrophobic or membranous (> 0) in nature. The compute pI/MW tool revealed that the extracted proteins were within the pI range of 3.5–11.5 and molecular weight of 4–186 kDa (Additional file 3: Figure S1b). 90% of the proteins were within the range of 80 kDa.
