Abstrakt: Phosphopantetheinyl transferases activate carrier proteins through attachment of a coenzyme A derived phosphopantetheinyl linker. This study describes a method to monitor this process through a modified HSCoA with an alkyne group, allowing for the Cu-catalysed alkyne-azide cycloaddition of a fluorescent tag. Application of the method in an enzyme screening resulted in the identification of new promiscuous PPTases.
