Abstract

The in-depth structural characterization of the phospho-isoforms obtained from a construct designed on the basis of sequence homology to the already characterized Insulin Receptor kinase domain (KD) was discussed. Incubation of the construct with ATP yielded a mixture of forms having a phosphorylation level ranging from one to three phosphate moieties per molecule. Six individual forms could be isolated through high-resolution anion-exchange chromatography. Each form was submitted to separate digestion with two enzymes having complementary specificity, namely, trypsin and AspN.
