Application

Orotic acid (OA) is an intermediate in de novo pyrimidine biosynthesis that may be used to study the specificity and kinetics of orotate phosphoribosyltransferase (OPRT) which catalyzes the reversible phosphoribosyl transfer from 5′-phospho-α-d-ribose 1′-diphosphate (PRPP) to orotic acid (OA), forming pyrophosphate and orotidine 5′-monophosphate (OMP). Orotic acid is used as a starting material for the potential commercial bioproduction of uridine 5′-monophosphate (UMP) by microbes such as Corynebacterium ammoniagenes (ATCC 6872) or Saccharomyces cerevisiae. OA may be used to study the AMPK/SREBP-1 dependent cell signaling pathway and transcription regulation mechanisms that induce hepatic lipogenesis.

The enzyme dihydroorotate dehydrogenase (DHODH) has been suggested as a promising target for the design of trypanocidal agents. We report here the discovery of novel inhibitors of Trypanosoma cruzi DHODH identified by a combination of virtual screening and ITC methods.

Nucleoside triphosphates (NTPs) are important synthetic targets with diverse applications in therapeutics and diagnostics. Enzymatic routes to NTPs from simple building blocks are attractive, however the cost and complexity of assembling the requisite mixtures of multiple enzymes hinders application. Here

Coordinated replication of eukaryotic genomes is intrinsically asymmetric, with continuous leading strand synthesis preceding discontinuous lagging strand synthesis. Here we provide two types of evidence indicating that, in fission yeast, these two biosynthetic tasks are performed by two different replicases.
