In Plant Bioinformatics we cover 33 plant-specific online tools from genome browsers to transcriptomic data mining to promoter/network analyses and others. Both of these tools were used in a study to find out the 2D and 3D structure of the HCV-1a NS4A protein from Pakistan patients. Figure 2. Such an analysis can help understand the biology of a set of protein coding sequences by identifying residues that might be important for biological function (those residues under negative selection) or those that might be involved in response to external influences, such as drugs, pathogens or other factors (residues under positive selection). Different types of tools and databases commonly used by researchers were reviewed to get an overall picture of bioinformatics techniques, computational biology tools and databases used in Hepatitis C Virus research. Moreover, the strength of the similarities (relationships) is varied, for-instance, in the case of the seven proteins, the similarities between NS5a and NS1 is stronger than with NS4a, while that of NS4a is stronger than with E1, while that of E1 is stronger than with E2, while that of E2 is stronger than with NS4b and NS3. The latest bioinformatics tools help scientists gain insights from a growing body of complex data. The database has around 44000 HCV (hepatitis C virus), 11000 HBV (hepatitis B virus) and 1600 HEV (Hepatitis E virus) sequences when it was made available to scientific community.
