Summary of the mass spectrometry data. The numbering is based on the location of the amino acid in wild-type K-bZIP; the N-terminal methionine of K-bZIP was removed when the His tag was added. The regions of HIS-K-bZIP that were identified by the MALDI-TOF analysis are shown in bold; the leucine zipper, basic region, and HIS tag are underlined; the CDK recognition site is overlined; and the phosphorylated amino acids within K-bZIP are indicated by an asterisk.
