The activity of enterochelin esterase results in the hydrolysis of enterobactin into the linear trimer, dimer and monomer of 2,3 dihydroxybenzoyl serine. An E.coli entS mutant is unable to secrete enterobactin efficiently but does have elevated levels of enterobactin breakdown products in the culture medium. Dihydroxybenzoyl serine is able to stimulate the growth of E.coli under iron limiting conditions by acting as a siderophore [Furrer02].
