Phosphorylation of chromosomal high mobility group (HMG) protein 14 by casein kinase II has been characterized. Two mol of 32P are incorporated per mol of bovine HMG 14. Kinetic analysis provided evidence for two distinct sites with apparent Km values of 14.5 and 134 microM and respective Vmax values of 0.17 and 0.68 mumol/min/mg casein kinase II. Tryptic peptide mapping identified two phosphorylated products, each with phosphoserine. Amino acid composition and sequence analysis demonstrate that the major high affinity phosphorylation site for casein kinase II is serine 89. This sequence located at the carboxyl-terminal of HMG 14 contains the primary sequence determinants for casein kinase II. On the basis of reverse-phase high performance liquid chromatography and amino acid analysis, HMG 14, serine 99 represents the low affinity phosphorylation site.
