Shree T, Khan SA, Saxena S., Subtractive Genomic identification of drug targets in Leishmania Donovani and Infantum, Onl J Bioinform., 14(2):138-145, 2013. Subtractive genomics can identify genes essential to a human parasite not present in a host to identify drug targets against Leishmania spp. Three potential proteins in Leishmania Donovani and Infantum are described which did not share sequence homology to human proteins when compared against genes present in the Database of Essential Genes. Glyoxylase II and 2-Hydroxymethyl-5-(7-methylamino-imidazol[4,5-b]pyridin-3-yl)-tetrahydro-furan-3-ol(HEMBL405920) were identified as targets in Leishmania infantum which bind to non-conserved residues in the human enzyme.
