Kinetic evaluation of glucose 1-phosphate analogues with a thymidylyltransferase using a continuous coupled enzyme assay.

چکیده
Cps2L, a thymidylytransferase, is the first enzyme in Streptococcus pneumoniae L-rhamnose biosynthesis and an antibacterial target. We herein report the evaluation of six sugar phosphate analogues selected to further probe Cps2L substrate tolerance. A modified continuous spectrophotometric assay was employed for facile detection of pyrophosphate (PPi) released from nucleotidylyltransfase-catalysed condensation of sugar 1-phosphates and nucleoside triphosphates to produce sugar nucleotides. Additionally, experiments using waterLOGSY NMR spectroscopy were investigated as a complimentary method to evaluate binding affinity to Cps2L.

Polyphosphate-containing bisubstrate analogues as inhibitors of a bacterial cell wall thymidylyltransferase.
A series of polyphosphate containing sugar nucleotide analogues were synthesized and evaluated as bisubstrate inhibitors of α-D-glucose 1-phosphate thymidylyltransferase Cps2L, the first enzyme in Streptococcus pneumoniael-rhamnose biosynthesis, and a novel antibacterial target. WaterLOGSY NMR spectroscopy demonstrated binding of bisubstrate analogues to Cps2L and a spectrophotometric coupled a...
متن کاملThe complex of Sphingomonas elodea ATCC 31461 glucose-1-phosphate uridylyltransferase with glucose-1-phosphate reveals a novel quaternary structure, unique among nucleoside diphosphate-sugar pyrophosphorylase members.
Gellan gum is a widely used commercial material, available in many different forms. Its economic importance has led to studies into the biosynthesis of exopolysaccharide gellan gum, which is industrially prepared in high yields using Sphingomonas elodea ATCC 31461. Glucose-1-phosphate uridylyltransferase mediates the reversible conversion of glucose-1-phosphate and UTP into UDP-glucose and pyro...
متن کاملThe molecular architecture of glucose-1-phosphate uridylyltransferase.
Glucose-1-phosphate uridylyltransferase, also referred to as UDP-glucose pyrophosphorylase or UGPase, catalyzes the formation of UDP-glucose from glucose-1-phosphate and UTP. Not surprisingly, given the central role of UDP-glucose in glycogen synthesis and in the production of glycolipids, glycoproteins, and proteoglycans, the enzyme is ubiquitous in nature. Interestingly, however, the prokaryo...
متن کاملMolecular Structure of -D-Glucose-1-phosphate Cytidylyltransferase from Salmonella typhi*
Dideoxysugars, which display biological activities ranging from mediating cell-cell interactions to serving as components in some antibiotics, are synthesized in various organisms via complex biochemical pathways that begin with the attachment of -D-glucose 1-phosphate to either CTP or dTTP. Here we describe the three-dimensional structure of the -D-glucose-1-phosphate cytidylyltransferase from...

A new, robust one-pot four-enzyme synthetic method was developed for thymidinediphosphate-l-rhamnose starting from d-glucose-1-phosphate. The enzymes, Glc-1-P thymidylyltransferase, dTDP-Glc-4,6-dehydratase, dTDP-4-keto-6-deoxy-Glc-3,5-epimerase and dTDP-4-keto-Rha reductase were derived from Streptococcus pneumonia serotype 23F, expressed in Escherichia coli, and studied in detail to provide t...
