Functional annotation of proteins helps greatly to strengthen our perception of life at the molecular level, which has tremendous pharmaceutical and biomedical significance. All the 44 EHPs were undertaken for domain analysis to predict possible functions using a variety of in silico tools (Supplementary file 1). However, successful annotation was confirmed for 24 EHPs with confidence by comparing results of the various tools used. The annotated proteins involved in diverse biological processes were classified into five categories, such as, enzymes, binding proteins, accessory proteins, cell division proteins, and transporters (Table , 5 and Fig. ).
