EryK coding sequence

Erythromycin C-12 hydroxylase coding sequence from Saccharopolyspora erythraea. The enzyme is responsible for the stereospecific hydroxylation of the macrolactone ring present in erythromycin D and erythromycin B.

Biology and Usage

In the last few years, much attention has been drawn to emerging contaminants due to their severe effects on human health and the lack of information about them. Among them, erythromycin has risen as a potential threat in developing antimicrobial resistance, and being capable of detecting it in water bodies can lead to the generation of measurements capable of degrading it.

In our project, erythromycin C-12 hydroxylase is used as a detector for the presence of erythromycin by catalyzing the oxidation of two stereoisomers of erythromycin, erythromycin B and D, to erythromycin C, requiring NADPH as a reagent and, therefore, obtaining NADP+ as a reaction product. Consequently, it is possible to evaluate the presence of erythromycin through a coupled reaction employing a NADP+/NADPH colorimetric assay.
