Characterization of the galU Gene of Streptococcus pneumoniae Encoding a Uridine Diphosphoglucose Pyrophosphorylase: A Gene Essential for Capsular Polysaccharide Biosynthesis

Abstract excerpt

The galU gene of Streptococcus pneumoniae has been cloned and sequenced. Escherichia coli cells harboring the recombinant plasmid pMMG2 (galU) overproduced a protein that has been shown to correspond to a uridine 5'-triphosphate:glucose-1-phosphate uridylyltransferase (uridine diphosphoglucose [UDP-Glc] pyrophosphorylase) responsible for the synthesis of UDP-Glc, a key compound in the biosynthesis of...
