Streptococcus pneumoniae is a multidrug-resistant pathogen that is a target of considerable interest for antibacterial drug development. One strategy for drug discovery is to inhibit an essential metabolic enzyme. The seventh step of the de novo purine-biosynthesis pathway converts carboxyaminoimidazoleribonucleotide (CAIR) and L-aspartic acid (Asp) to 4-(N-succino)-5-aminoimidazole-4-carboxamide ribonucleotide (SAICAR) in the presence of adenosine 5'-triphosphate (ATP) using the enzyme PurC ...
