Developments in scientific research follow improvements in computing—developments in bioinformatics, such as the interrogation of databases, have facilitated research into metabolic pathways.
Bioninformatics is the “Synthesis of molecular biology and computer science that develops databases and computational tools to store, retrieve, and analyze nucleic acid and protein sequence data.” (Pierce, B) and we have encountered it already in 7.3 Translation.
In addition to genes, though, bioinformatics can screen metabolic pathways and protein structures in order to assess potential targets for new drugs. For example, the Malaria Drug Target database allows researchers to search for potential inhibitors and targets in the malarial parasite, based on protein structure and function cross-referenced with genetic sequences. Many of these potential targets are key enzymes within metabolic pathways. Hasan et al. (2015) used a protein database to investigate the possibility of using the enzyme transketolase as a drug target. The enzyme is important in the pentose phosphate pathway, which is part of energy generation and nucleic acid synthesis (Hasan et al.). Analysis using various databases and computer software allowed the researchers to identify the enzyme, determine its structure and compare it to the human version of the enzyme. The result is a promising avenue for testing drugs to control the spread of Plasmodium falciparum, the malaria parasite.
