Abstract: Structural and functional bioinformatics help us to design and formulate prognostic computational models and frameworks that exploit our growing knowledge of biological macromolecules in terms of their structural orga- nization and functional capabilities. Integration of structural and functional biochemistry of macromolecules with informatics empowers significant progress in understanding the fundamentals of biology. Keywords: Cath; Scop; Haddock; Prosite; Vanted; Brenda Introduction Structural and functional bioinformatics aimed to unravel biological problems by analyzing sequences of biological mol- ecules such as DNA and protein using computational algorithms, informatics tools and software’s to assess molecular data[1]. Some of the applications of this novel field are given below: Prediction of protein structure: Understanding the correlation between amino acid sequence and the three dimensional structure of protein, it can be helpful for determining protein structure from its amino acid sequence[2]. Numerous bioinformatics tools could be utilized for protein structure and function prediction including secondary structure prediction[3], homology model- ing[4], protein threading[5], ab initio methods[6], prediction of motif[7], domain[8], transmembrane helix[9], signal peptide[10] etc. Some of these tools and databases used are summarized below in Table 1. Table 1: Protein structure/function prediction software’s and databases. S.no Tools and Databases Purpose 1 PDB (Protein Data Bank) Universal storage of 3D structure data of macromolecules.
