The Escherichia coli enterobactin biosynthetic protein EntB is a bifunctional enzyme that catalyzes hydrolysis of isochorismate via its N-terminal isochorismatase (IC) domain, and then transfers phosphopantetheinylated 2,3-DHB to EntF via the EntB C-terminal aryl carrier protein (ArCP) domain. Here we used a fluorescence anisotropy binding assay to invest ...

Enterobactin is a high-affinity iron chelator produced and secreted by Escherichia coli and Salmonella typhimurium to scavenge scarce extracellular Fe3+ as a micronutrient. EntC and EntB are the first two enzymes in the enterobactin biosynthetic pathway. Isochorismate, produced by EntC, is a substrate for EntB isochorismatase. By using a competing isochor ...
