Members of the arthropod-specific ecdysteroid kinase-like (EcKL) gene family are hypothesised to encode detoxicative kinases responsible for detoxification-by-phosphorylation. They are predicted to conjugate phosphate to secondary alcohols, using ATP as a phosphodonor. However, so far only one EcKL enzyme (ecdysteroid 22-kinase from Bombyx mori) has been characterised, phosphorylating ecdysteroids (insect growth and moulting hormones) at C-22, to form physiologically inactive ecdysteroid 22-phosphates.
