Small-molecule biosensors can be used to detect selective biocatalysis. (a) E. coli expressing the AcuR biosensor was incubated in the absence or presence of acrylate esters or acrylate for 3 h and then analyzed for luminescence. (b) E. coli expressing the estradiol biosensor was incubated in the absence or presence of methylated estradiol or estradiol for 3 h and then analyzed for luminescence. (c) E. coli expressing the IPTG biosensor was incubated in the absence or presence of IPTG esters or IPTG for 3 h and then analyzed for luminescence. (d) E. coli expressing the ABA biosensor was incubated in the absence or presence of ABA esters or ABA for 3 h and then analyzed for luminescence. Error bars are the standard deviation for n = 4 replicates.
